NORTHROP GRUMMAN TO ACQUIRE

COMPTEK RESEARCH, INC.



     LOS ANGELES, Calif. -- June 12, 2000 -- Northrop Grumman

Corporation (NYSE: NOC) announced today that it has signed a

definitive agreement to acquire Comptek Research Inc. (AMEX: CTK)

of Buffalo, N.Y., in a stock-for-stock transaction.  The

acquisition of Comptek Research, an electronic warfare (EW) and

information dominance company with fiscal year 2000 revenues of

$145 million, reflects Northrop Grumman's continuing strategic

thrust into electronic battle management, C4I and information

warfare.

     For each share of Comptek common stock, stockholders of

Comptek will receive a fraction of a Northrop Grumman share.  The

amount will be determined by dividing $20.75 by the average

closing price on the New York Stock Exchange for Northrop Grumman

common stock during the 20 trading days ending the business day

prior to the effective date of the registration statement and

proxy statement to Comptek shareholders.  In no event will the

exchange ratio be more than 0.2804:1 or less than 0.2470:1.

Should the average closing price of Northrop Grumman common stock

be less than $74 per share during this 20-day period, Comptek has

the right to terminate the transaction, subject to Northrop

Grumman's discretionary right to adjust the value.

     Northrop Grumman also reported today the sale of its

commercial aerostructures business to The Carlyle Group.  The

company said the acquisition of Comptek Research does not change

its earnings guidance for 2000.

     "This acquisition is an excellent strategic fit and enhances

our leadership position in advanced battle management and EW

systems integration," said Kent Kresa, Northrop Grumman's

chairman, president and chief executive officer.  "Comptek's

expertise in electronic warfare simulation and stimulation,

threat analysis, mission planning and precision targeting will

help create exciting new business opportunities for us."

     Comptek, with approximately 1,200 employees across the U.S.

and Canada, provides military systems and services to meet the

needs of its national and international defense customers.  The

company's core markets include tactical systems, EW

simulation/stimulation, and technical services.

     Following the close of the transaction, Comptek's business

units will be integrated into Northrop Grumman's existing

business operations.

     The transaction is subject to normal government reviews and

the approval of Comptek shareholders and is expected to close

within 60 days.

     Northrop Grumman had an average of 69.9 million shares

outstanding during the first quarter of 2000.  Comptek Research

had approximately 7.5 million equivalent shares outstanding at

the end of its fiscal year on March 31, 2000.

     Salomon Smith Barney is financial advisor to Northrop

Grumman in this transaction.

     Northrop Grumman Corporation, headquartered in Los Angeles,

is a world-class, high technology company providing innovative

solutions in systems integration, defense electronics and

information technology for its U.S. and international military,

government and commercial customers, as a prime contractor,

principal subcontractor, team member or preferred supplier.  The

company had revenues of $9 billion in 1999 and has a workforce of

approximately 45,000 employees.
