     This Amendment No. 24 (this "Amendment No. 24") amends and supplements the
Tender Offer Statement on Schedule TO as initially filed and dated May 23, 2001
(as previously amended and amended hereby, the "Schedule TO") filed by NORTHROP
GRUMMAN CORPORATION, a Delaware corporation ("Northrop Grumman") relating to the
offer (the "Offer") by Northrop Grumman to issue, upon the terms and subject to
the conditions set forth herein and in the related letter of election and
transmittal, shares of common stock, par value $1.00 per share (the "Northrop
Grumman Shares") designed to have a value of $67.50 per share or pay $67.50 per
share in cash (subject to the election and proration procedures and limitations
in the Prospectus (defined below) and related letter of election and
transmittal) for each outstanding share of common stock, par value $0.01 per
share (the "Common Stock") of NEWPORT NEWS SHIPBUILDING INC., a Delaware
corporation (the "Company") including the associated Series A participating
cumulative preferred stock purchase rights issued pursuant to the Company
stockholder protection rights agreement (the "Rights" and together with the
Common Stock, the "Newport News Shares").

     Northrop Grumman has filed a registration statement with the Securities and
Exchange Commission on Form S-4, relating to the Northrop Grumman Shares to be
issued to stockholders of Newport News in connection with the tender offer, as
set forth in the prospectus which is a part of the registration statement (the
"Prospectus"), and the related letter of election and transmittal, which were
annexed to the Schedule TO as Exhibits (a)(4) and (a)(1)(A) thereto.

     All of the information in the Prospectus and the related letter of election
and transmittal, and any prospectus supplement or other supplement thereto
related to the offer hereafter filed with the Securities and Exchange Commission
by Northrop Grumman, is hereby incorporated by reference in answer to items 2
through 11 of the Schedule TO.


Items 1, 4, 5, 6 and 11.

     Items 1, 4, 5, 6 and 11 are hereby amended and supplemented as follows:

     On November 8, 2001, Northrop Grumman and the Company announced that they
had signed a definitive merger agreement providing for the acquisition of
Newport News by Northrop Grumman. A copy of the merger agreement and the press
release announcing the merger agreement are being filed as exhibits to this
Schedule TO and are incorporated herein by reference.

     Pursuant to an Agreement and Plan of Merger dated as of November 7, 2001
(the "Northrop Grumman Merger Agreement"), among Northrop Grumman, Purchaser
Corp. I, a wholly owned subsidiary of Northrop Grumman (the "Purchaser"), and
the Company, a copy of which is filed herewith as Exhibit (a)(5)(CC), Northrop
Grumman will amend the Northrop Grumman Offer: (a) to change the offer price to
a price designed to provide a value of $67.50 per share in cash and/or Northrop
Grumman common stock, as described below under "--The Northrop Grumman Offer
Consideration"; (b) to designate the Purchaser as the bidder under the Northrop
Grumman Offer; and (c) set November 29, 2001 as the initial expiration date for
the Northrop Grumman Offer. After the Purchaser has consummated the Northrop
Grumman Offer, the Company will be merged with and into Purchaser (the "Northrop
Grumman Merger") and Purchaser will continue as the surviving corporation and as
a wholly owned subsidiary of Northrop Grumman. In the Northrop Grumman Merger,
stockholders of the Company will receive cash and/or Northrop Grumman common
stock, as applicable, designed to provide a value of $67.50 in exchange for each
Company Share, as described below under "-- The Northrop Grumman Merger
Consideration".

     The parties intend to consummate the Northrop Grumman Offer and the
Northrop Grumman Merger as soon as practicable following the satisfaction or
waiver of the conditions to closing set forth in the Northrop Grumman Merger
Agreement. The Northrop Grumman Offer is conditioned upon, among other things,
(i) acceptance of the Northrop Grumman Offer by holders of a majority of the
Company Shares (on a fully diluted basis), (ii) the registration statement on
Form S-4 filed by Northrop Grumman in connection with the Northrop Grumman Offer
having been declared effective by the Securities and Exchange Commission and not
subject to any stop order and (iii) other customary closing conditions.

The Northrop Grumman Offer Consideration

     Offer Consideration to Be Paid. On the terms and subject to the conditions
of the Northrop Grumman Offer, Northrop Grumman will exchange a combination of
cash and newly issued Northrop Grumman common stock for Company Shares validly
tendered in the Northrop Grumman Offer.

     Election Right. Each Company stockholder will have the right to
elect to receive, for those Company Shares he or she validly tenders in the
Northrop Grumman Offer, either

     .  $67.50 in cash, without interest, per Company Share; or

     .  a number of shares of Northrop Grumman common stock (the
        "exchange ratio") designed to provide a value of $67.50 per
        Company Share,

subject, in each case, to the election and proration procedures and limitations
described below.

     Northrop Grumman will determine the exact exchange ratio by dividing
$67.50 by the average of the closing sale prices for a share of Northrop Grumman
common stock on the New York Stock Exchange as reported in The Wall Street
Journal over the 5-day trading period ending on the trading day immediately
preceding the second full trading day before the expiration of the Northrop
Grumman Offer (the "Northrop Grumman Stock Value"). However, in no event will
the exchange ratio be more than .84375 ($67.50/$80.00) or less than .675
($67.50/$100.00). Northrop Grumman will issue a press release before 9:00 A.M.,
New York City time, on the second full trading day before the expiration of the
Northrop Grumman Offer, announcing the exchange ratio and the Northrop Grumman
Stock Value.

     Northrop Grumman will issue 16,636,885 shares of its common stock (the
"Northrop Grumman Available Shares") in the Northrop Grumman Offer and the
Northrop Grumman Merger. The portion of these shares available in the Northrop
Grumman Offer (the "Offer Shares") will equal the number of Northrop Grumman
Available Shares times the percentage of outstanding Company Shares tendered in
the Northrop Grumman Offer.  All Northrop Grumman Available Shares not exchanged
in the Northrop Grumman Offer will be issued in the Northrop Grumman Merger (the
"Remaining Northrop Grumman Available Shares").

     Northrop Grumman will pay $892,026,990 in cash for the Company Shares in
the Northrop Grumman Offer and the Northrop Grumman Merger (the "Base Cash
Amount"), subject to (i) increase for fractional shares, (ii) the adjustments as
provided below plus (iii) the number of outstanding Company Shares increases due
to option exercises minus (iv) certain indebtedness repaid to the Company with
Company Shares, as contemplated in the Northrop Grumman Merger Agreement (the
"Adjusted Cash Amount").  The adjustments to the Base Cash Amount referred to in
clause (ii) above are as follows:

         .  If the Northrop Grumman Stock Value is less than $90.00 but
         equal to or greater than $80.00, Northrop Grumman will increase
         the aggregate amount of cash available for the Northrop Grumman
         Offer and the Northrop Grumman Merger by the product of (a) the
         excess of $90.00 over the Northrop Grumman Stock Value and (b)
         the number of Northrop Grumman Available Shares.

         .  If the Northrop Grumman Stock Value is less than $80.00,
         Northrop Grumman will increase the aggregate of amount of cash
         available for the Northrop Grumman Offer and the Northrop Grumman
         Merger by $166,368,850.

         .  If the Northrop Grumman Stock Value is greater than
         $90.00 but less than or equal to $100.00, Northrop Grumman will
         reduce the aggregate amount of cash available for the Northrop
         Grumman Offer and the Northrop Grumman Merger by the product of
         (a) the excess of the Northrop Grumman Stock Value over $90.00
         and (b) the number of Northrop Grumman Available Shares.

         .  If the Northrop Grumman Stock Value is greater than
         $100.00, Northrop Grumman will reduce the aggregate of amount of
         cash available for the Northrop Grumman Offer and the Northrop
         Grumman Merger by $166,368,850.

The amount of cash available in the Northrop Grumman Offer (the "Offer Cash
Amount") will equal the Adjusted Cash Amount multiplied by the percentage of
outstanding Company Shares tendered in the Northrop Grumman Offer.

     Because of the manner in which the exchange ratio is calculated,
holders of Company shares who receive solely Northrop Grumman common stock or a
combination of Northrop Grumman common stock and cash in the Northrop Grumman
Offer or the Northrop Grumman Merger will receive $67.50 per Company Share of
value (based on the Northrop Grumman Stock Value) if the Northrop Grumman Stock
Value is between $80.00 and $100.00, will receive less than $67.50 per Company
Share of value if the Northrop Grumman Stock Value is less than $80.00 and will
receive more than $67.50 per Company Share of value if the Northrop Grumman
Stock Value is more than $100.00.

     Consequences of Over- and Under-Election. If Company stockholders
elect to receive pursuant to the Northrop Grumman Offer cash in excess of the
Offer Cash Amount, the amount of cash that Company stockholders will receive for
each Company Share for which they made a cash election will be reduced pro rata
so the total amount of cash that Northrop Grumman will pay to all Company
stockholders in the Northrop Grumman Offer will equal the Offer Cash Amount. If
this reduction occurs, in addition to the reduced amount of cash, Northrop
Grumman will issue, in respect of each Company Share for which a cash election
was made, shares of Northrop Grumman common stock in lieu of the cash the
Company stockholder would have otherwise received. The number of shares of
Northrop Grumman common stock to be issued for each Company Share subject to a
cash reduction in this situation will be calculated by multiplying the exchange
ratio by the percentage reduction in the cash consideration paid to Company
stockholders making cash elections.

     If Company stockholders elect to receive pursuant to the Northrop
Grumman Offer shares of Northrop Grumman common stock in excess of the Offer
Shares, the number of shares of Northrop Grumman common stock Company
stockholders will receive for each Company Share for which they made that share
election will be reduced pro rata so that the total number of shares that
Northrop Grumman will issue to all Company stockholders in the Northrop Grumman
Offer will equal the Offer Shares. If this reduction occurs, in addition to the
reduced number of Northrop Grumman shares, Northrop Grumman will pay, in respect
of each Company Share for which a share election was made, cash in lieu of the
Northrop Grumman shares that the Company stockholder would have otherwise
received. The amount of cash to be paid for each Company Share subject to a
share election in this situation will be calculated by multiplying $67.50 by the
percentage reduction in Northrop Grumman shares issued to Company stockholders
making share elections.

     In the case of an over-election for either cash or Northrop Grumman
shares, those Company stockholders who fail to make a valid election with
respect to their shares will receive the under-elected form of consideration for
those shares.  If all Company stockholders together make valid cash elections
for less than the Offer Cash Amount and valid share elections for fewer than all
the Offer Shares, all of the remaining cash and Northrop Grumman shares that
will be paid and issued in Northrop Grumman Offer will be allocated pro rata
among non-electing holders of Company Shares.

The Northrop Grumman Merger Consideration

     Merger Consideration to Be Paid. On the terms and subject to the
conditions of the Northrop Grumman Merger Agreement, Northrop Grumman will
exchange a combination of cash and newly issued Northrop Grumman common stock
for all Company Shares outstanding at the time Northrop Grumman completes the
Northrop Grumman Merger.

     Election Right. Each Company stockholder may make for each Company
Share exchanged pursuant to the Northrop Grumman Merger, either an election (i)
for $67.50 in cash or (ii) for shares of Northrop Grumman common stock, subject,
in each case, to the election and proration procedures and limitations described
below.

     Consequences of Over- and Under-Election. Pursuant to the Northrop
Grumman Merger, Northrop Grumman will (a) issue the Remaining Northrop Grumman
Available Shares and (b) distribute cash in an amount equal to (i) the Adjusted
Cash Amount minus (ii) the amount of cash paid in the Northrop Grumman Offer
(the "Remaining Cash Amount"), subject to increase for fractional shares.

     If Company stockholders elect to receive pursuant to the Northrop
Grumman Merger cash in excess of the Remaining Cash Amount, the amount of cash
that Company stockholders will receive for each Company Share for which they
made a cash election will be reduced pro rata so that the total amount of cash
that Northrop Grumman will pay to all Company stockholders pursuant to the
Northrop Grumman Merger will equal the Remaining Cash Amount.  If this reduction
occurs, in addition to the reduced cash, Northrop Grumman will issue, in respect
of each Company Share for which a cash election was made, shares of Northrop
Grumman common stock in lieu of the cash the Company stockholders would have
otherwise received.  The number of shares of Northrop Grumman common stock to be
issued for each Company Share subject to a cash reduction in this situation will
be calculated by multiplying the exchange ratio by the percentage reduction in
the cash consideration paid to Company stockholders making cash elections.

     If Company stockholders elect to receive pursuant to the Northrop
Grumman Merger shares of Northrop Grumman common stock in excess of the number
of Remaining Northrop Grumman Available Shares, the number of shares of Northrop
Grumman common stock that Company stockholders will receive for each Company
Share for which they made a share election will be reduced pro rata so that the
total number of shares that Northrop Grumman will issue to all Company
stockholders pursuant to the Northrop Grumman Merger will equal the number of
Remaining Northrop Grumman Available Shares.  If this reduction occurs, in
addition to the reduced number of Northrop Grumman shares, Northrop Grumman will
pay, in respect of each Company Share for which a share election was made, cash
in lieu of the Northrop Grumman shares that the Company stockholder would have
otherwise received.  The amount of cash to be paid for each Company Share
subject to a share reduction in this situation will be calculated by multiplying
$67.50 by the percentage reduction in Northrop Grumman shares issued to Company
stockholders making share elections.

     In the case of an over-election for either cash or shares of Northrop
Grumman shares, those Company stockholders who fail to make a valid election
with respect to their shares will receive the under-elected form of
consideration for those shares.  If all Company stockholders together make valid
cash elections for less than the Remaining Cash Amount and valid share elections
for fewer than the Remaining Northrop Grumman Available Shares pursuant to the
Northrop Grumman Merger, all of the remaining cash and Northrop Grumman shares
that will be paid and issued pursuant to the Northrop Grumman Merger will be
allocated pro rata among non-electing holders of Company Shares.

     All references to the Northrop Grumman Merger Agreement are qualified
in their entirety by the full text of the Northrop Grumman  Merger Agreement, a
copy of which is attached as Exhibit (a)(5)(CC) hereto and is incorporated by
reference herein.

     Northrop Grumman will promptly amend the Form S-4 and Prospectus to reflect
the terms of the Northrop Grumman Merger Agreement.
