                               EXPLANATORY NOTE
                  POST-EFFECTIVE AMENDMENT NO. 1 TO FORM S-8

     This post-effective amendment is being filed pursuant to Rule 414 under the
Securities Exchange Act of 1933, as amended (the "Securities Act"), to reflect
the creation by Northrop Grumman Systems Corporation (formerly Northrop Grumman
Corporation), a Delaware corporation ("Systems"), of a new holding company,
Northrop Grumman Corporation (formerly NNG, Inc.) a Delaware corporation ("New
Northrop Grumman"), above Systems.  The creation of New Northrop Grumman was
effected pursuant to an Amended and Restated Agreement and Plan of Merger (the
"Amended Merger Agreement"), dated January 23, 2001, among New Northrop Grumman,
Systems, Litton Industries, Inc., a Delaware corporation ("Litton") and LII
Acquisition Corp., a Delaware corporation and wholly owned subsidiary of New
Northrop Grumman ("LII").

     As contemplated by the Amended Merger Agreement, on April 2, 2001, Systems
completed a corporate reorganization (the "Northrop Reorganization") that was
effected by action of its Board of Directors without a vote of Systems'
stockholders, pursuant to Section 251(g) of the Delaware General Corporation Law
(the "DGCL") and an Agreement and Plan of Merger, dated as of March 20, 2001
(the "Merger Agreement"), between Systems, New Northrop Grumman and NGC
Acquisition Corp., a Delaware corporation and indirect wholly-owned subsidiary
of Systems ("NGC").  In the Northrop Reorganization, NGC was merged with and
into Systems, with Systems as the surviving corporation and a wholly-owned
subsidiary of New Northrop Grumman, the new holding company.  Pursuant to the
requirements of Section 251(g) of the DGCL, at the effective time of that merger
and in connection with the Northrop Reorganization, New Northrop Grumman changed
its name from NNG, Inc. to "Northrop Grumman Corporation," and Systems changed
its name to "Northrop Grumman Systems Corporation."  Upon consummation of the
Northrop Reorganization and in accordance with Section 251(g) of the DGCL, (a)
all of the outstanding shares of capital stock of Systems were automatically
converted into the same number of shares of the same class of capital stock of
New Northrop Grumman, and (b) each certificate representing shares of Northrop
capital stock, without any action on the part of the holder thereof, is now
deemed to represent an equal number of shares of the same class of capital stock
of New Northrop Grumman.

     In accordance with Rule 414 under the Securities Act, New Northrop Grumman,
as the successor issuer to Systems, hereby expressly adopts this registration
statement as its own for all purposes of the Securities Act and the Securities
Exchange Act of 1934, as amended.  The Northrop Grumman Savings and Investment
Plan (the "Plan") to which this registration statement relates shall continue to
be known as the Northrop Grumman Savings and Investment Plan.  The Plan
continues to cover employees of Systems.  However, shares of stock issued in
accordance with the Plan shall be shares of stock of the New Northrop Grumman
rather than shares of stock of Systems.

     The applicable registration fees were paid at the time of the original
filing of this registration statement.
