     Re:  Registration Statement on Form S-8

Ladies and Gentlemen:

     I am a member of the bars of the States of New York and
California.  I am also Corporate Vice President, Secretary and
Associate General Counsel of Northrop Grumman Corporation, a
Delaware corporation (the "Company").  I am familiar with the
Registration Statement on Form S-8 (the "Registration Statement")
being filed by the Company with the Securities and Exchange
Commission under the Securities Act of 1933, as amended, in
connection with the Company's registration of 8,000,000 shares of
common stock, par value $1.00 per share (the "Common Stock"),
issuable under the Northrop Grumman Corporation 2001 Long-Term
Incentive Stock Plan (the "Plan").

     At your request, I have examined the Company's certificate
of incorporation and bylaws and originals or copies certified or
otherwise identified to my satisfaction of such other documents,
corporate records, certificates of public officials and other
instruments as I have deemed necessary or advisable for the
purpose of rendering this opinion.

     Based on the foregoing and upon such matters of fact and law
as I have deemed relevant, I am of the opinion that the Common
Stock has been duly authorized by all necessary corporate action
on the part of the Company and, when issued in accordance with
such authorization, the provisions of the Plan and relevant
agreements duly authorized by and in accordance with the terms of
the Plan, will be validly issued, fully paid and non-assessable.

     I hereby consent to the inclusion of this opinion as an
Exhibit to the Registration Statement.

                                   Very truly yours,

                                   /S/ JOHN H. MULLAN
                                  ---------------------

                                   Corporate Vice President,
                                   Secretary and
                                   Associate General Counsel
