Dear Ms. Cvrkel:

This letter is in reference to your letter dated March 26, 2010 containing comments of the staff of the Division of Corporation Finance on the Form 10-K of Northrop Grumman Corporation (the “Company”) described above.

Pursuant to my telephone call on April 5 with Joe Foti of your office, the Company requires additional time to respond fully to the comments and has therefore requested an extension of time to respond. I am confirming that, in accordance with my discussion with Mr. Foti, the Company anticipates responding to the comments contained in the March 26 letter on or before May 7, 2010.

If you have any questions, please call me at (310) 201-3452.
