        This Post-Effective Amendment No. 2 is being filed to de-register 18,146 shares of common stock of Northrop Grumman Space & Mission Systems Corp., formerly TRW Inc. (the "Registrant").

        The shares were among the 80,000 shares registered under a Registration Statement on Form S-8, Registration No. 333-61192 (the "Registration Statement") for the TRW Canada Stock Savings Plan (the "Plan"), originally filed with the Commission on May 18, 2001. On December 11, 2002, pursuant to an agreement of merger, all of the outstanding shares of the Registrant, including those held by the Plan, were acquired by Northrop Grumman Corporation ("Northrop") in exchange for shares of Northrop. As a result, the Registrant is a wholly owned subsidiary of Northrop, and securities of the Registrant are no longer offered to or purchasable by participants in the Plan.
