THE COMPANY
GENERAL
Northrop Grumman Corporation (the "Company" or "Northrop Grumman"), formerly
known as Northrop Corporation, is an advanced technology company that designs,
develops and manufactures military aircraft, missiles and unmanned aeronautical
vehicles, military and commercial aircraft and assemblies and sophisticated
electronic systems. The Company also provides technical and information services
to civilian and governmental customers.
In May 1994, the Company completed the acquisition of Grumman Corporation
("Grumman") and changed its name to "Northrop Grumman Corporation." Grumman
common stock was acquired for an aggregate purchase price of approximately $2.17
billion financed by borrowings against credit facilities provided by a syndicate
of commercial banks. If the Company and Grumman had been combined during 1993,
pro forma sales for that year would have been approximately $8 billion. See
"Recent Developments."
In August 1994, the Company purchased the remaining 51% of the parent
company of Vought Aircraft Company ("Vought") that it did not previously own for
$130 million. Vought, a manufacturer of major subassemblies for both commercial
and military aircraft, had annual sales in 1993 of $972.1 million. See "Recent
Developments."
The combined Company has significant experience in the design and
manufacture of tactical and strategic military aircraft with particular
expertise in both stealth and naval airframe technologies. The Company has
developed leading technologies in the increasingly important area of military
electronic systems, and its experience in the integration of large, complex
systems positions it to be a significant competitor for future aircraft and
electronic systems integration programs. In addition, the Company is one of the
largest manufacturers of commercial aircraft assemblies.
The acquisitions of Grumman and Vought were intended, among other things, to
provide greater stability to revenue and cash flow generation and to allow the
Company to maintain critical skills during the consolidation of the aerospace
industry. The Company's major programs are in transition from the research and
development phase to the production phase, where the Company has historically
realized improved margins.
Northrop Grumman programs include several which are important to current
Department of Defense procurement strategies. Northrop Grumman is the prime
contractor on the B-2 Stealth Bomber, the only bomber program currently in
production; the principal subcontractor on the F/A-18 Hornet Strike fighter, one
of the principal fighter aircraft used by the U.S. Navy as well as numerous
foreign countries; the prime contractor on the E-2C Hawkeye, the U.S. Navy's
principal early warning, command and control aircraft; and the prime contractor
for the JSTARS aircraft radar system, which will be the advanced airborne
surveillance and battle management system for the Air Force and Army. The
Company also participates in the commercial aircraft subassembly market as a
principal subcontractor to The Boeing Company on the 747 jetliner program as
well as providing components for other commercial aircraft.
By the end of 1994 the Company expects to have completed the organization of
its consolidated business activities within five divisions: B-2 Division (B-2),
Commercial Aircraft Division (CAD), Military Aircraft Division (MAD),
Electronics and Systems Integration Division (ESID) and Data Systems and
Services Division (DSSD).
B-2 DIVISION
The B-2 Division will continue to be responsible for the Company's B-2
"Stealth" bomber program. The B-2, for which the Company is the prime
contractor, is the Company's largest program. The B-2 program has provided an
increasing amount of operating margin as the mix of sales continues its shift
from relatively low-margin research and development work to production work. The
B-2 is unique in that it is a
S-2
<PAGE>
strategic, long-range heavy bomber with low observable technology effective at
both high and low altitudes. It is designed to penetrate sophisticated air
defenses while having the range and payload capabilities of a contemporary heavy
bomber. These unique characteristics combined with the fact that it is the only
U.S. bomber program currently in production make the B-2 particularly important
to the U.S. Air Force. The B-2 program currently contemplates 20 operational
aircraft through the purchase of 21 aircraft, of which 3 have been delivered.
Deliveries of the remaining aircraft in final operational form are expected to
be made through 1999. In addition to being responsible for current B-2 program
contracts, the B-2 Division will be responsible for future upgrades to the B-2
aircraft, providing depot support and spares, and weapons systems integration
and augmentation.
COMMERCIAL AIRCRAFT DIVISION
The combined Company's commercial aircraft production activities make it one
of the largest commercial aircraft component manufacturers in the world. The
Commercial Aircraft Division will be responsible for the Company's production of
components for commercial aircraft and certain components for military aircraft.
These components include the fuselage and major portions of the tail section for
the Boeing 747, major subassemblies for the Boeing 757 and 767 as well as the
McDonnell Douglas C-17 military transport, various other components for the
Boeing 757, 767, and 777, and components for other aircraft. This division will
include the manufacturing activities of Vought which was acquired in August,
1994. See "Recent Developments." The Company believes that with the acquisition
of Vought it is well positioned to be a significant competitor for future
commercial aircraft component opportunities.
MILITARY AIRCRAFT DIVISION
The Military Aircraft Division is responsible for pursuing the Company's
military aircraft and missile programs and their derivatives. This Division will
manage the F/A-18 program, the Tri-Service Standoff Attack Missile (TSSAM)
program, and the marketing of upgrade services for older aircraft.
The F/A-18 is the United States Navy's primary strike/attack aircraft
currently in production and is deployed by the Navy from aircraft carriers and
by the Marines from air bases. The Company produces the center and aft fuselage,
twin vertical tails, and all associated subsystems for the F/A-18 as a
subcontractor to McDonnell Douglas. Several foreign governments have purchased
the F/A-18. Advanced versions of the
F/A-18 are now being developed and are expected to be deployed starting in 1998.
The TSSAM is a stealthy subsonic cruise missile that has been designed to
attack high-value land and sea targets using an autonomous guidance system to
deliver either a single conventional warhead or multiple munitions. The Company
has been the prime contractor on this classified program pursuant to a
fixed-price contract since it began in 1986. Although current plans call for
development and production of 4,156 missiles, the program is the only Company
program which was included in an August 1994 Defense Department memorandum
requesting proposals from the armed services for cutting, delaying or replacing
ten programs.
ELECTRONICS AND SYSTEMS INTEGRATION DIVISION
The Electronics and Systems Integration Division will manage the Company's
Joint Surveillance Target Attack Radar System (JSTARS) program, the E-2C Hawkeye
early warning and control aircraft program, the Brilliant Anti-Tank (BAT) weapon
system program, and its electronic countermeasures, sensors, and guidance
systems programs.
Northrop Grumman is the prime contractor for JSTARS. JSTARS is an advanced
airborne radar system currently under development which is designed to provide
real-time detection, location, classification, and tracking of hostile moving
and stationary targets. JSTARS' surveillance capabilities will enable it to be a
critical part of the military's future battlefield management system. Two
aircraft containing prototype systems were deployed and successfully used during
Desert Storm. The Company is nearing completion of the development phase and
production version deliveries are expected to begin in 1996 and to continue
through the end of the decade.
The E-2C Hawkeye is a carrier-based, twin-turboprop powered, all-weather,
airborne early warning and control aircraft that is designed for missions such
as air defense, search-and-rescue, strike control, and air traffic control. The
Company is the prime contractor on this program. Versions of the E-2 have flown
since 1960, and deliveries to the United States Navy and various foreign
customers are expected to continue through 2000.
S-3
<PAGE>
The Company is the prime contractor on the BAT "Brilliant" self-guided
submunition program. The BAT can be carried by a variety of air vehicles. When
deployed, the BAT is designed to autonomously find, attack, and destroy tanks,
armored vehicles and other mobile targets by using acoustic and infrared sensors
working in combination with a high speed onboard computer. Prototype production
began in 1992 as part of the engineering and manufacturing development phase of
the program.
DATA SYSTEMS AND SERVICES DIVISION
The Data Systems and Services Division will be responsible for internal data
processing system activities as well as marketing similar services to external
customers. Included among these services are Space Shuttle technical services,
space station program support services, flight simulator maintenance services
and the development of data processing systems for a wide variety of United
States Government entities and applications.
RECENT DEVELOPMENTS
In May 1994, the Company completed the acquisition of Grumman through the
acquisition of all outstanding Grumman common stock for an aggregate purchase
price of approximately $2.17 billion. The acquisition was financed by borrowings
against the term portion of credit facilities provided by a syndicate of
commercial banks. Grumman's financial data have been consolidated with Northrop
Grumman's effective April 1, 1994.
In August 1994, the Company purchased the remaining 51% of the parent
company of Vought that it did not previously own for $130 million. Vought is a
manufacturer of major subassemblies for both commercial and military aircraft.
Vought's principal programs currently include the manufacture of portions of the
tail section for the Boeing 747, 757 and 767, and the McDonnell Douglas C-17. In
1993, Vought reported annual sales of $972.1 million and net income of
approximately $16.1 million.
In September 1994, the Company announced a plan to reduce its workforce by
9,000 people over the next 15 months as part of an effort to cut costs ahead of
anticipated sales reductions and to streamline and consolidate operations. The
announced plan includes the offer of a voluntary early retirement program to
approximately 5,000 eligible participants in the main Northrop retirement plan
and a one time benefit increase for retirees in that plan. The Company estimated
that assuming a 60% acceptance rate in the voluntary early retirement program
these changes would result in a one-time charge against earnings for the 1994
fiscal fourth quarter of approximately $300 million to reflect the plan's
increased actuarial liability. The exact amount of the charge would not be known
until after a November 15, 1994 acceptance deadline. The Company reported that
costs associated with the early retirement plan and the retiree benefit
adjustment would be met by the excess of assets over plan liabilities in the
Northrop pension plan and would not have a direct cash impact on the Company.
The Company also announced that it is evaluating future facilities
requirements in light of industry downsizing and the consolidation of Grumman
and Vought. At this time, the financial impact, if any, arising from that
evaluation cannot be determined.
The Company has under consideration the possible merger of the Northrop
pension plan and the Grumman pension plan. The Grumman pension plan is currently
underfunded and cash contributions to this plan have been estimated at
approximately $500 million over the next five years. If the Company merges the
two plans it would substantially reduce or eliminate the need for these
contributions as the Grumman pension plan underfunding would be offset by the
surplus in the Northrop pension plan, thus reducing the excess of assets over
projected benefit obligations in the Northrop pension plan. Reduction in excess
assets in the Northrop pension plan will reduce the noncash earnings of the
Company in future periods attributable to pension income.
In September 1994, the Company agreed to settle for $53 million a previously
disclosed lawsuit brought by Data General Corporation against subsidiaries of
Grumman following an appeals court ruling. The difference between the settlement
payment and the amount previously provided for will be among the adjustments to
the preliminary estimates used in allocating the Grumman purchase price.
USE OF PROCEEDS
The net proceeds from the sale of the Offered Debt Securities, estimated to
be , will be used to repay indebtedness under the Company's bank term
credit facility incurred in connection with the Grumman acquisition which
currently bears interest at LIBOR plus .62% per annum and is payable in
quarterly installments, with the last payment due in March 1999.

NOTES TO PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
(UNAUDITED)
(a) Adjustments to record $2 billion in term loans obtained to finance the
acquisition of Grumman, accrued $127 million for the payment of the balance
of Grumman shares still outstanding along with additional acquisition
related costs and to assign the purchase price to assets acquired and
liabilities assumed. The allocation of the purchase price to assets and
liabilities is based on preliminary estimates of their respective fair
values and may subsequently be adjusted.
(b) Adjustment to reflect the Special Purpose Vehicles industry segment as
discontinued operations. Management intends to dispose of the Special
Purpose Vehicles industry segment previously operated by Grumman and
therefore these operations have been excluded from the Statements of
Operations and included in the caption Investment in and advances to
affiliates and sundry assets on the Statement of Financial Position.
(c) Adjustment to reflect change in the method of recognizing revenue on certain
government contracts applied by Grumman to conform with revenue recognition
policy applied by Northrop.
(d) Adjustment to record Grumman retiree benefits liabilities in excess of
market value of assets at March 31, 1994. Management is in the process of
reviewing the Grumman health and welfare benefit plans and based on the

SINKING FUND

Securities.
GLOBAL SECURITIES
The Offered Debt Securities will be issued in the form of one or more
registered Global Securities that will be deposited with, or on behalf of, the
Depositary and registered in the name of the Depositary's nominee. Such Global
Securities will be issued in a denomination or aggregate denominations equal to
the portion of the aggregate principal amount of Offered Debt Securities of the
series to be represented by such Global Security or Securities. Unless and until
it is exchanged in whole for Debt Securities in definitive registered form, a
Global Security may not be transferred except as a whole by the Depositary for
such Global Security to a nominee of such Depositary or by a nominee of such

The Depositary has advised the Company and the Underwriters as follows: the

Banking Law, a "banking organization" within the meaning of the New York Banking
Law, a member of the Federal Reserve System, a "clearing corporation"
S-10
<PAGE>
within the meaning of the New York Uniform Commercial Code, and a "clearing
agency" registered pursuant to the provisions of Section 17A of the Securities
Exchange Act of 1934. The Depositary was created to hold securities of its
participating organizations ("participants") and to facilitate the clearance and
settlement of securities transactions, such as transfers and pledges, among its
participants in such securities through electronic computerized book-entry
changes in accounts of the participants, thereby eliminating the need for
physical movement of securities certificates. Participants include securities
brokers and dealers (including the Underwriters), banks, trust companies,
clearing corporations and certain other organizations, some of whom (and/or
their representative) own the Depositary. Access to the Depositary's book-entry
system is also available to others, such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly. Persons who are not participants may
beneficially own securities held by the Depositary only through participants.
A further description of the Depositary's procedures with respect to the
Global Securities is set forth in the Prospectus under "Description of Debt
Securities -- Global Debt Securities."
