NORTHROP GRUMMAN REPORTS
------------------------
FIRST QUARTER 2002 RESULTS
--------------------------

Sales Up 106 Percent

Segment Operating Margin Increases 81 Percent
Confirms 2002 Guidance of $6.60 - $7.10 EEPS

     LOS ANGELES -- April 17, 2002 -- Northrop Grumman Corporation (NYSE: NOC)
today reported first quarter 2002 net income of $149 million, or $1.27 per
share, compared with net income of $132 million, or $1.81 per share, for the
same period of 2001, adjusted for SFAS No. 142 - Goodwill and Other Intangible
Assets. The comparable per share decline reflects a substantial decrease in
pension income and increases in interest expense and in the number of shares
outstanding. On an economic earnings basis, the company reported increased
earnings of $170 million, or $1.45 per share, compared with $101 million, or
$1.39 per share, for the same period of 2001. First quarter 2002 earnings per
share are based on average diluted shares outstanding of 112.8 million versus
72.8 million for the first quarter of 2001.

     "We are very pleased with our first quarter results which reflect the
contributions of last year's three strategic acquisitions, coupled with strong
organic growth and

earnings," stated Kent Kresa, Northrop Grumman chairman and chief executive
officer. "Northrop Grumman is now the nation's third-largest defense contractor,
with a powerful portfolio of industry-leading businesses and key technologies.
With the strength and diversity of this portfolio, we expect to continue to
benefit from the nation's highest defense budget in recent years. We are
reaffirming our 2002 financial guidance targets and our expectations for
double-digit revenue and economic earnings growth in 2003."

     Kresa added, "We are excited about our proposed acquisition of TRW. Its
space and satellite business perfectly complements our defense capabilities.
Based on our demonstrated ability to successfully integrate acquired companies,
we expect a completed transaction will lead to enhanced value for our
shareholders."

     Dr. Ronald D. Sugar, Northrop Grumman president and chief operating
officer, commented, "Our team has again demonstrated its expertise in seamlessly
integrating new businesses into Northrop Grumman. With our April 1 announcement
of the completion of the integration of Newport News Shipbuilding, all three of
the company's 2001 acquisitions have been successfully completed. With this
behind us, we are in an excellent position to focus our attention on the
integration of TRW later this year, should our offer be successful.

     "We remain focused on execution in all of our businesses. Our first quarter
results reflect strong operating performance from five of our six sectors.
Component Technologies, our smallest sector, continues to be negatively affected
by the downturn in the telecommunications market," Sugar added.

     Effective Jan. 1, 2002, the company adopted the provisions of SFAS No.142
eliminating the amortization of goodwill. As a result, all 2001 and 2002
discussions of operating results exclude goodwill amortization. Further details
are contained in the Additional Financial Information section. The company is
evaluating and analyzing other provisions of SFAS No. 142 and expects to
complete these reviews during 2002.

NORTHROP GRUMMAN REPORTS
------------------------
FIRST QUARTER 2002 RESULTS
--------------------------


     The 2002 first quarter results include the operations of Litton Industries,
Inc. (Litton), acquired in the second quarter of 2001 and Newport News
Shipbuilding, Inc. (Newport News) and the Electronics and Information Systems
Group of Aerojet General (EIS), both acquired in the fourth quarter of 2001.
These acquisitions are important components of the increase in sales, operating
margin and net income for the 2002 first quarter compared with the first quarter
of 2001.

     Sales for the first quarter more than doubled to $4.1 billion from $2.0
billion reported for the first quarter of 2001. Northrop Grumman's operating
margin for the quarter increased 39 percent to $313 million from an adjusted
$225 million in the same period a year ago. The 2002 first quarter operating
margin included $24 million of pension income, significantly lower than the $69
million reported in the first quarter of 2001. The company said that pension
income for 2002 is expected to total $95 million compared with $337 million
reported for 2001.

     Sales at Electronics Systems in the 2002 first quarter increased 76 percent
to $1.2 billion from $701 million for the same period of 2001, including a 16
percent increase in organic sales. Operating margin for the quarter was $99
million compared to 2001 first quarter adjusted operating margin of $53 million.
The sales and margin increases reflect the contributions by Litton's electronics
businesses and EIS.

     Ships, which includes the financial results of the Newport News and Ship
Systems sectors, generated sales of $1.1 billion and operating margin of $79
million for the first quarter of 2002. Although Newport News is now operating as
a separate Northrop Grumman sector, the company has aggregated Newport News and
Ship Systems results for financial reporting purposes.

     Information Technology reported sales of $929 million in the quarter ended
March 31, 2002, an increase of 58 percent over the same period a year ago. The
sales

growth was driven by businesses added in the Litton acquisition. Operating
margin was $50 million in the quarter, up from an adjusted $34 million in the
first quarter of 2001.

     Sales for Integrated Systems increased 10 percent to $807 million for the
2002 first quarter compared with $733 million for the same period a year ago,
reflecting higher B-2 and unmanned vehicle sales. Operating margin for the 2002
first quarter increased 6 percent to $93 million from an adjusted $88 million in
the comparable year ago period.

     Component Technologies reported 2002 first quarter sales of $125 million
and an operating loss of $4 million. Component Technologies' operating margin
continued to be adversely impacted by the downturn in the telecommunications
industry. Looking ahead, the sector remains well positioned to capitalize on a
market turnaround. Component Technologies continues to generate solid
performance in its non-telecommunications business.

     Contract acquisitions increased to $5.8 billion for the first three months
of 2002 from $2.2 billion reported for the same period a year ago. For the first
quarter 2002, the company's Electronics Systems segment reported contract
acquisitions of $1.5 billion reflecting the inclusion of Litton and EIS
businesses and higher F-22 funding in the combat avionics business area. Ships
reported contract acquisitions of $1.8 billion resulting from the funding of
Virginia-class submarines and refueling and overhaul of the carrier USS
Enterprise. Information Technology reported contract acquisitions of $1.1
billion, principally in the government information technology business area.
Integrated Systems reported $1.3 billion in contract acquisitions, reflecting
higher F/A-18E/F and unmanned vehicle systems funding. Component Technologies
reported $129 million in contract acquisitions. The company's business backlog
at March 31, 2002, was $22.4 billion, more than double the $10.3 billion
reported a year earlier.

FIRST QUARTER 2002 RESULTS
--------------------------

     In the first quarter of 2002 the company used cash from operations of $99
million compared with a use of $33 million for the same period last year.

     Northrop Grumman's net debt at March 31, 2002, was $5.4 billion, up from
the $5.0 billion reported at Dec. 31, 2001, reflecting in part cash expenditures
to complete the Newport News acquisition. Interest expense for the first quarter
increased to $109 million from $47 million reported in the 2001 first quarter,
as a result of the company's financing activities related to the acquisitions of
Litton, Newport News and EIS. Debt to total capital was 40 percent at the end of
the first quarter.

     As previously announced, the company has issued an exchange offer to
purchase all of the outstanding stock of TRW.

     There can be no assurance that such a transaction will be completed.
