Experts

The consolidated financial statements of Northrop Grumman Corporation and subsidiaries (the “Company”) as of December 31, 2024 and 2023, and
for each of the three years in the period ended December 31, 2024, incorporated by reference in this Prospectus, and the effectiveness of the Company’s internal control over financial reporting, have been audited by Deloitte &
Touche LLP, an independent registered public accounting firm, as stated in their reports. Such financial statements are incorporated by reference in reliance upon the reports of such firm given their authority as experts in accounting and auditing.

With respect to the unaudited interim financial information for the periods ended March 31, 2025 and 2024, which is incorporated by reference
herein, Deloitte & Touche LLP, an independent registered public accounting firm, has applied limited procedures in accordance with the standards of the Public Company Accounting Oversight Board (United States) for a review of such
information. However, as stated in their report included in the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2025 and incorporated by reference herein, they did not audit
and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied.
Deloitte & Touche LLP is not subject to the liability provisions of Section 11 of the Securities Act for their reports on the unaudited interim financial information because those reports are not “reports” or a
“part” of the Registration Statement prepared or certified by an accountant within the meaning of Sections 7 and 11 of the Securities Act.
