(iii) Exchange Offer. Upon the occurrence of an offer made by the Company to exchange (each, an “Exchange Offer”) Initial Notes or Additional Notes, if any, of a series bearing the Restricted Notes Legend for exchange notes which will be registered under the Securities Act and have terms identical in all material respects to such Initial Notes or such Additional Notes, as the case may be (the “Exchange Notes”), including the Exchange Offers contemplated by a Registration Rights Agreement, the Company shall execute a Company Order in accordance with Section 303 of the Original Indenture with respect to each applicable series of Notes, and the Trustee shall authenticate, one or more Global Notes not bearing the Restricted Notes Legend in an aggregate principal amount equal to the principal amount of the beneficial interests in the Global Notes of each applicable series that are Restricted Notes tendered for acceptance in accordance with the applicable Exchange Offer and accepted for exchange in such Exchange Offer. Concurrently with the issuance of such Global Notes, the Security Registrar shall cause the aggregate principal amount of the applicable Restricted Notes to be reduced accordingly, and the Security Registrar shall cause to be delivered to the Persons designated by the Holders of such Restricted Notes so accepted Global Notes not bearing the Restricted Notes Legend in the appropriate principal amount.

(iv) Restricted Notes Legend. Upon the transfer, exchange or replacement of one or more Notes that do not and are not required to bear the Restricted Notes Legend (“Unrestricted Notes”), the Security Registrar shall deliver Unrestricted Notes that do not bear the Restricted Notes Legend. Upon the transfer, exchange or replacement of Restricted Notes of any series, other than in exchange for Exchange Notes pursuant to an Exchange Offer, the Security Registrar shall cause to be delivered only Restricted Notes that bear the Restricted Notes Legend unless the Restricted Notes Legend is no longer required by paragraph (d) above and there is delivered to the Trustee an Opinion of Counsel and an Officers’ Certificate of the Company, each to the effect that neither such legend nor the related restrictions on transfer are required in order to ensure that subsequent transfers of such Notes are effected in compliance with the Securities Act. Upon receipt of such Opinion of Counsel and Officers’ Certificate of the Company, the Trustee shall direct the Security Registrar to exchange the applicable Restricted Notes for Unrestricted Notes of such series with such exchange to occur in accordance with paragraph (v) below (in the case of Global Notes).

(v) Acknowledgement of Transfer Restrictions. By its acceptance of any Note bearing the Restricted Notes Legend, each Holder of such a Note acknowledges receipt of a Restricted Note with the restrictions on transfer of such Note set forth in this Tenth Supplemental Indenture and in the Restricted Notes Legend and agrees that it shall transfer such Note only as provided in this Tenth Supplemental Indenture until such time as the Restricted Notes Legend is no longer required pursuant to paragraph (d) above and

8

such Holder transfers such a Restricted Note to an Unrestricted Note. The Security Registrar shall not register a transfer of any Note unless such transfer complies with the restrictions on transfer of such Note set forth in this Tenth Supplemental Indenture. In connection with any transfer of Notes, each Holder agrees by its acceptance of the Notes to furnish the Trustee, the Security Registrar or the Company such certifications, legal opinions or other information as any of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act until such time as the Restricted Notes Legend is no longer required pursuant to paragraph (d) above and such Holder transfers such a Restricted Note to an Unrestricted Note; provided that the Security Registrar shall not be required to determine (but may rely on a determination made by the Company with respect to) the sufficiency of any such certifications, legal opinions or other information.

The Security Registrar shall retain copies of all letters, notices and other written communications received pursuant to this paragraph (e) in accordance with its customary procedures.

None of the Trustee, the Security Registrar or any agent thereof shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture, this Tenth Supplemental Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Agent Members or beneficial owners of interests in any Global Notes) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, the Indenture or this Tenth Supplemental Indenture, and to examine the same to determine substantial compliance as to form with the express requirements thereof or hereof.

The Company will pay the principal of and premium, if any, and interest on the Notes in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. The Company will make all payments of interest on any Global Note in accordance with the arrangements then existing between the Paying Agent and the applicable Depositary, and all payments of principal of and premium, if any, on any Global Note at the Corporate Trust Office upon surrender of such Note for payment. The Company will make all payments of interest on any definitive Note by mailing a check to the address of each Person entitled thereto, and all payments of principal of and premium, if any, on any definitive Note at the Corporate Trust Office upon surrender of such Note for payment.

If any Additional Interest will be due pursuant to the terms of the Registration Rights Agreement in respect of a series of Notes, prior to the time such Additional Interest is payable, the Company shall deliver an Officers’ Certificate to the Trustee and Paying Agent setting forth the Additional Interest per $1,000 aggregate principal amount of such Notes and the date from which such Additional Interest shall accrue. The Company shall also deliver an Officers’ Certificate to the Trustee and the Paying Agent setting forth the date after which such Additional Interest shall cease accruing. Neither the Trustee nor the Paying Agent shall have any

7.875% Senior Note due 2026

1. Principal and Interest. NORTHROP GRUMMAN CORPORATION, a corporation duly organized and existing under the laws of Delaware (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to [________________]⁵ [CEDE & CO.]⁶, or registered assigns, the principal sum of ________________ Dollars (or such greater or lesser amount as is set forth in Schedule A hereto), on March 1, 2026 (the “Maturity Date”), and to pay interest thereon from September 1, 2021 (the “Original Accrual Date”), or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on March 1 and September 1 in each year (each an “Interest Payment Date”), commencing March 1, 2022, at the rate of 7.875% per annum until the principal hereof is paid or made available for payment. Interest will be computed on the basis of a 360-day year of twelve 30-day months[; provided that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest (“Additional Interest”) shall accrue on this Note if and to the extent provided for in accordance with the terms of the Registration Rights Agreement]⁷. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date and on the Maturity Date will, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities to this Note (the “Predecessor Notes”)) is registered at the close of business on the February 15 or August 15 (whether or not a Business Day) (each, a “Regular Record Date”), as the case may be, next preceding such Interest Payment Date or the Maturity Date, as applicable. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to such Person on such Regular Record Date and may either be paid to the Holder in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee under the Indenture, notice whereof shall be given to Holders of Notes not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest accrued from and including the immediately preceding Interest Payment Date (or from and including the Original Accrual Date, in the case of

the initial Interest Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be. If an Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the payment will be made on the next Business Day as if it were made on the date the payment was due, and no interest will accrue on the amount so payable for the period from and after that Interest Payment Date or the Maturity Date, as the case may be. [All references to any amount of “interest payable” on or with respect to this Note in the Indenture or this Note shall be deemed to include any applicable Additional Interest that may be payable on this Note.]

2. Method of Payment. The Company will pay the principal of and premium, if any, and interest on the Notes in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. [The Company will make all payments of interest on this Global Note in accordance with the arrangements then existing between the Paying Agent and the Depositary, and all payments of principal of and premium, if any, on this Global Note at the Corporate Trust Office upon surrender of this Global Note for payment.]⁸ [The Company will make all payments of interest on this Note by mailing a check to the address of the Person entitled thereto, and all payments of principal of and premium, if any, on this Note at the Corporate Trust Office upon surrender of this Note for payment.]⁹

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof, directly or through an Authenticating Agent, by manual or electronic signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

3. Paying Agent and Security Registrar. The Trustee shall initially act as the Paying Agent and Security Registrar in respect of the Notes and its Corporate Trust Office is designated as a place where the Notes may be presented for payment or for registration of transfer or exchange. The Company may, however, change the Paying Agent or Security Registrar for the Notes without prior notice to any Holders, and the Company or any Subsidiary may act as Paying Agent or Security Registrar for the Notes.

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental Indenture dated as of March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”), and a Tenth Supplemental Indenture dated as of September 2, 2021 (the “Tenth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture, the “Indenture”), by and between the Company and The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered.

This Note is one of the series designated as the “7.875% Senior Notes due 2026” of the Company initially limited in aggregate principal amount to $76,490,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”). Any such Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date and the initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided, however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from the Notes. Additional series of Securities may be issued pursuant to the Indenture.

The Notes are unsecured senior obligations of the Company and rank pari passu with all unsecured and unsubordinated obligations of the Company.

The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all those terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

Capitalized terms used but not defined in this Note have the respective meanings ascribed to them by the Indenture.

5. Optional Redemption. The Notes are not redeemable prior to the Maturity Date of March 1, 2026.

6. Sinking Fund. The Notes are not subject to any sinking fund or analogous provisions.

7. Denominations; Transfer; Exchange. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of this Note, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or exchange, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

8. Persons Deemed Owner. The Holder of this Note may be treated as the owner of this Note for all purposes.

9. Unclaimed Funds. If money for the payment of principal, premium or interest of or on the Notes remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request, subject to any applicable abandoned property laws. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee or any Paying Agent for payment.

10. Defeasance and Discharge. The Notes will be subject to defeasance and discharge as set forth in Section 1302 of the Original Indenture and to covenant defeasance as set forth in Section 1303 of the Original Indenture.

11. Amendment; Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

12. Defaults and Remedies. If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless: the Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes; the Holders of not less than 25% in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity; the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein (including, in case of a redemption, on the Redemption Date).

13. Obligations Absolute. No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

14. No Recourse Against Others. No recourse shall be had for the payment of the principal of, or premium, if any, or interest on this Note, or for any claim based hereon or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

15. Trustee Dealings with the Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

16. Successors and Assigns. All covenants and agreements in the Indenture by the Company shall bind its successors and assigns, whether so expressed or not, except as provided in Section 802 of the Original Indenture.

17. Governing Law. THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

18. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders thereof. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental Indenture dated as of March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”), and a Tenth Supplemental Indenture dated as of September 2, 2021 (the “Tenth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture, the “Indenture”), by and between the Company and The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered.

This Note is one of the series designated as the “7.750% Senior Notes due 2026” of the Company initially limited in aggregate principal amount to $47,828,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”). Any such Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date and the initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided, however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from the Notes. Additional series of Securities may be issued pursuant to the Indenture.

The Notes are unsecured senior obligations of the Company and rank pari passu with all unsecured and unsubordinated obligations of the Company.

The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all those terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

Capitalized terms used but not defined in this Note have the respective meanings ascribed to them by the Indenture.

5. Optional Redemption. The Notes are subject to redemption, as a whole or in part, at any time or from time to time, at the option of the Company, in principal amounts of $1,000 and integral multiples of $1,000 above such amount (provided that the unredeemed portion of any Note redeemed in part may not be less than $2,000), on at least 30 days but not more than 60 days prior notice as provided in the Indenture. The Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate (as defined below), as determined by the Independent Investment Banker (as defined below), plus 10 basis points, and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including, the Redemption Date.

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the Tenth Supplemental Indenture.

“Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes.

“Comparable Treasury Price” means, with respect to any Redemption Date, (A) the arithmetic mean of the Reference Treasury Dealer Quotations received for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such quotation.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company to act as the “Independent Investment Banker.”

“Reference Treasury Dealer” means (A) BofA Securities, Inc., BNP Paribas Securities Corp. and Wells Fargo Securities LLC (or their respective affiliates which are primary U.S. Government securities dealers in the United States (“Primary Treasury Dealers”)), and their respective successors; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the arithmetic mean, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 3:30 p.m. (New York City time) on the third Business Day preceding such Redemption Date.

The Company shall give the Trustee notice of the Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation.

In connection with any redemption of the Notes in part, if the Notes are represented by one or more Global Notes, interests in the Notes will be selected for redemption by the Depositary in accordance with its standard procedures therefor.

6. Sinking Fund. The Notes are not subject to any sinking fund or analogous provisions.

7. Denominations; Transfer; Exchange. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of this Note, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or exchange, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. If the Notes are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Notes during the period beginning at the opening of business 15 days before the day of the mailing of the applicable notice of redemption and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Note so selected for redemption in whole or in part (except the unredeemed portion of any Note being redeemed in part).

8. Persons Deemed Owner. The Holder of this Note may be treated as the owner of this Note for all purposes.

9. Unclaimed Funds. If money for the payment of principal, premium or interest of or on the Notes remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request, subject to any applicable abandoned property laws. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee or any Paying Agent for payment.

10. Defeasance and Discharge. The Notes will be subject to defeasance and discharge as set forth in Section 1302 of the Original Indenture and to covenant defeasance as set forth in Section 1303 of the Original Indenture.

11. Amendment; Waiver.

The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

12. Defaults and Remedies. If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless: the Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes; the Holders of not less than 25% in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity; the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein (including, in case of a redemption, on the Redemption Date).

13. Obligations Absolute. No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

14. No Recourse Against Others. No recourse shall be had for the payment of the principal of, or premium, if any, or interest on this Note, or for any claim based hereon or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

15. Trustee Dealings with the Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

NORTHROP GRUMMAN CORPORATION

7.750% Senior Note due 2029

1. Principal and Interest. NORTHROP GRUMMAN CORPORATION, a corporation duly organized and existing under the laws of Delaware (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to [________________]³² [CEDE & CO.]³³, or registered assigns, the principal sum of ________________ Dollars (or such greater or lesser amount as is set forth in Schedule A hereto), on June 1, 2029 (the “Maturity Date”), and to pay interest thereon from June 1, 2021 (the “Original Accrual Date”), or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on June 1 and December 1 in each year (each an “Interest Payment Date”), commencing December 1, 2021, at the rate of 7.750% per annum until the principal hereof is paid or made available for payment. Interest will be computed on the basis of a 360-day year of twelve 30-day months[; provided that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest (“Additional Interest”) shall accrue on this Note if and to the extent provided for in accordance with the terms of the Registration Rights Agreement]³⁴. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date and on the Maturity Date will, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities to this Note (the “Predecessor Notes”)) is registered at the close of business on the May 15 or November 15 (whether or not a Business Day) (each, a “Regular Record Date”), as the case may be, next preceding such Interest Payment Date or the Maturity Date, as applicable. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to such Person on such Regular Record Date and may either be paid to the Holder in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee under the Indenture, notice whereof shall be given to Holders of Notes not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest accrued from and including the immediately preceding Interest Payment Date (or from and including the Original Accrual Date, in the case of the initial Interest Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be. If an Interest Payment Date or the Maturity Date falls on a

day that is not a Business Day, the payment will be made on the next Business Day as if it were made on the date the payment was due, and no interest will accrue on the amount so payable for the period from and after that Interest Payment Date or the Maturity Date, as the case may be. [All references to any amount of “interest payable” on or with respect to this Note in the Indenture or this Note shall be deemed to include any applicable Additional Interest that may be payable on this Note.]

2. Method of Payment. The Company will pay the principal of and premium, if any, and interest on the Notes in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. [The Company will make all payments of interest on this Global Note in accordance with the arrangements then existing between the Paying Agent and the Depositary, and all payments of principal of and premium, if any, on this Global Note at the Corporate Trust Office upon surrender of this Global Note for payment.]³⁵ [The Company will make all payments of interest on this Note by mailing a check to the address of the Person entitled thereto, and all payments of principal of and premium, if any, on this Note at the Corporate Trust Office upon surrender of this Note for payment.]³⁶

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof, directly or through an Authenticating Agent, by manual or electronic signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

IN WITNESS WHEREOF, the Company has caused this Note to be duly executed.

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental Indenture dated as of March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”), and a Tenth Supplemental Indenture dated as of September 2, 2021 (the “Tenth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture, the “Indenture”), by and between the Company and The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered.

This Note is one of the series designated as the “7.750% Senior Notes due 2029” of the Company initially limited in aggregate principal amount to $79,323,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”). Any such Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date and the initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided, however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from the Notes. Additional series of Securities may be issued pursuant to the Indenture.

The Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate (as defined below), as determined by the Independent Investment Banker (as defined below), plus 25 basis points, and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including, the Redemption Date.

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the Tenth Supplemental Indenture.

NORTHROP GRUMMAN CORPORATION

7.750% Senior Note due 2031

1. Principal and Interest. NORTHROP GRUMMAN CORPORATION, a corporation duly organized and existing under the laws of Delaware (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to [________________]⁴¹ [CEDE & CO.]⁴², or registered assigns, the principal sum of ________________ Dollars (or such greater or lesser amount as is set forth in Schedule A hereto), on February 15, 2031 (the “Maturity Date”), and to pay interest thereon from August 15, 2021 (the “Original Accrual Date”), or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on February 15 and August 15 in each year (each an “Interest Payment Date”), commencing February 15, 2022, at the rate of 7.750% per annum until the principal hereof is paid or made available for payment. Interest will be computed on the basis of a 360-day year of twelve 30-day months[; provided that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest (“Additional Interest”) shall accrue on this Note if and to the extent provided for in accordance with the terms of the Registration Rights Agreement]⁴³. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date and on the Maturity Date will, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities to this Note (the “Predecessor Notes”)) is registered at the close of business on the February 1 or August 1 (whether or not a Business Day) (each, a “Regular Record Date”), as the case may be, next preceding such Interest Payment Date or the Maturity Date, as applicable. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to such Person on such Regular Record Date and may either be paid to the Holder in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee under the Indenture, notice whereof shall be given to Holders of Notes not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest accrued from and including the immediately preceding Interest Payment Date (or from and including the Original Accrual Date, in the case of the initial Interest Payment Date) to but excluding the applicable Interest

Payment Date or the Maturity Date, as the case may be. If an Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the payment will be made on the next Business Day as if it were made on the date the payment was due, and no interest will accrue on the amount so payable for the period from and after that Interest Payment Date or the Maturity Date, as the case may be. [All references to any amount of “interest payable” on or with respect to this Note in the Indenture or this Note shall be deemed to include any applicable Additional Interest that may be payable on this Note.]

2. Method of Payment. The Company will pay the principal of and premium, if any, and interest on the Notes in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. [The Company will make all payments of interest on this Global Note in accordance with the arrangements then existing between the Paying Agent and the Depositary, and all payments of principal of and premium, if any, on this Global Note at the Corporate Trust Office upon surrender of this Global Note for payment.]⁴⁴ [The Company will make all payments of interest on this Note by mailing a check to the address of the Person entitled thereto, and all payments of principal of and premium, if any, on this Note at the Corporate Trust Office upon surrender of this Note for payment.]⁴⁵

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof, directly or through an Authenticating Agent, by manual or electronic signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

IN WITNESS WHEREOF, the Company has caused this Note to be duly executed.

[FORM OF REVERSE SIDE OF 2031 NOTE]

7.750% Senior Note due 2031

3. Paying Agent and Security Registrar. The Trustee shall initially act as the Paying Agent and Security Registrar in respect of the Notes and its Corporate Trust Office is designated as a place where the Notes may be presented for payment or for registration of transfer or exchange. The Company may, however, change the Paying Agent or Security Registrar for the Notes without prior notice to any Holders, and the Company or any Subsidiary may act as Paying Agent or Security Registrar for the Notes.

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental Indenture dated as of March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”), and a Tenth Supplemental Indenture dated as of September 2, 2021 (the “Tenth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture, the “Indenture”), by and between the Company and The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered.

This Note is one of the series designated as the “7.750% Senior Notes due 2031” of the Company initially limited in aggregate principal amount to $166,864,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”). Any such Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date and the initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided, however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from the Notes. Additional series of Securities may be issued pursuant to the Indenture.

The Notes are unsecured senior obligations of the Company and rank pari passu with all unsecured and unsubordinated obligations of the Company.

The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all those terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

Capitalized terms used but not defined in this Note have the respective meanings ascribed to them by the Indenture.

5. Optional Redemption. The Notes are subject to redemption, as a whole or in part, at any time or from time to time, at the option of the Company, in principal amounts of $1,000 and integral multiples of $1,000 above such amount (provided that the unredeemed portion of any Note redeemed in part may not be less than $2,000), on at least 30 days but not more than 60 days prior notice as provided in the Indenture. The Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate (as defined below), as determined by the Independent Investment Banker (as defined below), plus 30 basis points, and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including, the Redemption Date.

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the Tenth Supplemental Indenture.

“Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes.

“Comparable Treasury Price” means, with respect to any Redemption Date, (A) the arithmetic mean of the Reference Treasury Dealer Quotations received for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such quotation.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company to act as the “Independent Investment Banker.”

“Reference Treasury Dealer” means (A) BofA Securities, Inc., BNP Paribas Securities Corp. and Wells Fargo Securities LLC (or their respective affiliates which are primary U.S. Government securities dealers in the United States (“Primary Treasury Dealers”)), and their respective successors; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the arithmetic mean, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 3:30 p.m. (New York City time) on the third Business Day preceding such Redemption Date.

The Company shall give the Trustee notice of the Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation.

In connection with any redemption of the Notes in part, if the Notes are represented by one or more Global Notes, interests in the Notes will be selected for redemption by the Depositary in accordance with its standard procedures therefor.

6. Sinking Fund. The Notes are not subject to any sinking fund or analogous provisions.

7. Denominations; Transfer; Exchange. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of this Note, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or exchange, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. If the Notes are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Notes during the period beginning at the opening of business 15 days before the day of the mailing of the applicable notice of redemption and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Note so selected for redemption in whole or in part (except the unredeemed portion of any Note being redeemed in part).

8. Persons Deemed Owner. The Holder of this Note may be treated as the owner of this Note for all purposes.

9. Unclaimed Funds. If money for the payment of principal, premium or interest of or on the Notes remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request, subject to any applicable abandoned property laws. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee or any Paying Agent for payment.

10. Defeasance and Discharge. The Notes will be subject to defeasance and discharge as set forth in Section 1302 of the Original Indenture and to covenant defeasance as set forth in Section 1303 of the Original Indenture.

11. Amendment; Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

12. Defaults and Remedies. If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless: the Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes; the Holders of not less than 25% in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity; the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein (including, in case of a redemption, on the Redemption Date).

13. Obligations Absolute. No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

14. No Recourse Against Others. No recourse shall be had for the payment of the principal of, or premium, if any, or interest on this Note, or for any claim based hereon or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

15. Trustee Dealings with the Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

16. Successors and Assigns. All covenants and agreements in the Indenture by the Company shall bind its successors and assigns, whether so expressed or not, except as provided in Section 802 of the Original Indenture.

17. Governing Law. THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

NORTHROP GRUMMAN CORPORATION

6.980% Senior Note due 2036

1. Principal and Interest. NORTHROP GRUMMAN CORPORATION, a corporation duly organized and existing under the laws of Delaware (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to [________________]⁵⁰ [CEDE & CO.]⁵¹, or registered assigns, the principal sum of ________________ Dollars (or such greater or lesser amount as is set forth in Schedule A hereto), on March 15, 2036 (the “Maturity Date”), and to pay interest thereon from March 15, 2021 (the “Original Accrual Date”), or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on March 15 and September 15 in each year (each an “Interest Payment Date”), commencing September 15, 2021, at the rate of 6.980% per annum until the principal hereof is paid or made available for payment. Interest will be computed on the basis of a 360-day year of twelve 30-day months[; provided that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest (“Additional Interest”) shall accrue on this Note if and to the extent provided for in accordance with the terms of the Registration Rights Agreement]⁵². The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date and on the Maturity Date will, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities to this Note (the “Predecessor Notes”)) is registered at the close of business on the February 28 or August 31 (whether or not a Business Day) (each, a “Regular Record Date”), as the case may be, next preceding such Interest Payment Date or the Maturity Date, as applicable; provided that the interest payable on September 15, 2021 will be paid to the Persons in whose name this Note is registered at the close of business on September 2, 2021. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to such Person on such Regular Record Date and may either be paid to the Holder in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee under the Indenture, notice whereof shall be given to Holders of Notes not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest accrued from and including the immediately preceding Interest Payment Date (or from and including the Original Accrual Date, in the case of the initial Interest

Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be. If an Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the payment will be made on the next Business Day as if it were made on the date the payment was due, and no interest will accrue on the amount so payable for the period from and after that Interest Payment Date or the Maturity Date, as the case may be. [All references to any amount of “interest payable” on or with respect to this Note in the Indenture or this Note shall be deemed to include any applicable Additional Interest that may be payable on this Note.]

2. Method of Payment. The Company will pay the principal of and premium, if any, and interest on the Notes in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. [The Company will make all payments of interest on this Global Note in accordance with the arrangements then existing between the Paying Agent and the Depositary, and all payments of principal of and premium, if any, on this Global Note at the Corporate Trust Office upon surrender of this Global Note for payment.]⁵³ [The Company will make all payments of interest on this Note by mailing a check to the address of the Person entitled thereto, and all payments of principal of and premium, if any, on this Note at the Corporate Trust Office upon surrender of this Note for payment.]⁵⁴

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof, directly or through an Authenticating Agent, by manual or electronic signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

IN WITNESS WHEREOF, the Company has caused this Note to be duly executed.

[FORM OF REVERSE SIDE OF 2036 NOTE]

6.980% Senior Note due 2036

3. Paying Agent and Security Registrar. The Trustee shall initially act as the Paying Agent and Security Registrar in respect of the Notes and its Corporate Trust Office is designated as a place where the Notes may be presented for payment or for registration of transfer or exchange. The Company may, however, change the Paying Agent or Security Registrar for the Notes without prior notice to any Holders, and the Company or any Subsidiary may act as Paying Agent or Security Registrar for the Notes.

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental Indenture dated as of March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”), and a Tenth Supplemental Indenture dated as of September 2, 2021 (the “Tenth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture, the “Indenture”), by and between the Company and The Bank of New York Mellon, as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered.

This Note is one of the series designated as the “6.980% Senior Notes due 2036” of the Company initially limited in aggregate principal amount to $12,300,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”). Any such Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date and the initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided, however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from the Notes. Additional series of Securities may be issued pursuant to the Indenture.

The Notes are unsecured senior obligations of the Company and rank pari passu with all unsecured and unsubordinated obligations of the Company.

The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all those terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

Capitalized terms used but not defined in this Note have the respective meanings ascribed to them by the Indenture.

5. Optional Redemption. The Notes are subject to redemption, as a whole or in part, at any time or from time to time, at the option of the Company, in principal amounts of $1,000 and integral multiples of $1,000 above such amount (provided that the unredeemed portion of any Note redeemed in part may not be less than $2,000), on at least 30 days but not more than 60 days prior notice as provided in the Indenture. The Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate (as defined below), as determined by the Independent Investment Banker (as defined below), plus 10 basis points, and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including, the Redemption Date.

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the Tenth Supplemental Indenture.

“Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes.

“Comparable Treasury Price” means, with respect to any Redemption Date, (A) the arithmetic mean of the Reference Treasury Dealer Quotations received for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such quotation.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company to act as the “Independent Investment Banker.”

“Reference Treasury Dealer” means (A) BofA Securities, Inc., BNP Paribas Securities Corp. and Wells Fargo Securities LLC (or their respective affiliates which are primary U.S. Government securities dealers in the United States (“Primary Treasury Dealers”)), and their respective successors; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the arithmetic mean, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 3:30 p.m. (New York City time) on the third Business Day preceding such Redemption Date.

The Company shall give the Trustee notice of the Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation.

In connection with any redemption of the Notes in part, if the Notes are represented by one or more Global Notes, interests in the Notes will be selected for redemption by the Depositary in accordance with its standard procedures therefor.

6. Sinking Fund. The Notes are not subject to any sinking fund or analogous provisions.

7. Denominations; Transfer; Exchange. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of this Note, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or exchange, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. If the Notes are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Notes during the period beginning at the opening of business 15 days before the day of the mailing of the applicable notice of redemption and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Note so selected for redemption in whole or in part (except the unredeemed portion of any Note being redeemed in part).

8. Persons Deemed Owner. The Holder of this Note may be treated as the owner of this Note for all purposes.

9. Unclaimed Funds. If money for the payment of principal, premium or interest of or on the Notes remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request, subject to any applicable abandoned property laws. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee or any Paying Agent for payment.

10. Defeasance and Discharge. The Notes will be subject to defeasance and discharge as set forth in Section 1302 of the Original Indenture and to covenant defeasance as set forth in Section 1303 of the Original Indenture.

11. Amendment; Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

12. Defaults and Remedies. If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless: the Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes; the Holders of not less than 25% in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity; the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein (including, in case of a redemption, on the Redemption Date).

13. Obligations Absolute. No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

14. No Recourse Against Others. No recourse shall be had for the payment of the principal of, or premium, if any, or interest on this Note, or for any claim based hereon or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

15. Trustee Dealings with the Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

16. Successors and Assigns. All covenants and agreements in the Indenture by the Company shall bind its successors and assigns, whether so expressed or not, except as provided in Section 802 of the Original Indenture.

17. Governing Law. THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

18. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders thereof. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

The Company will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to:
