            $0.20 PER SHARE ACCRETION EXPECTED IN FIRST FULL YEAR
            -----------------------------------------------------

         PARSIPPANY, N.J., SEPTEMBER 22 -- DRS Technologies, Inc. (NYSE:
DRS) and Engineered Support Systems, Inc. (NASDAQ: EASI) jointly announced
today that they have signed a definitive agreement for DRS to acquire all of
the outstanding stock of Engineered Support Systems, Inc. (ESSI) for $43.00
per share through a combination of cash and DRS common stock.

         The acquisition is expected to be accretive for DRS in its first
full fiscal year of operation with DRS ending March 31, 2007, contributing
approximately $0.20 to earnings per share and approximately $1.23 billion to
revenues.

         Upon completion of the acquisition, ESSI will become DRS's third
operating group, focused on support and services.

STRATEGIC HIGHLIGHTS

         In making the announcement, Mark S. Newman, DRS Technologies'
chairman, president and chief executive officer, commented, "The acquisition
of Engineered Support Systems will create a strong, diverse company, adding
a significant business base in technical and logistics support services,
integrated military electronics and support equipment with broad access to a
variety of government funding accounts, including procurement and operations
and maintenance (O&M). Engineered Support Systems is uniquely focused on
sustainment of military forces and respected as a rapid-response solutions
provider. The combination of the two companies will firmly establish DRS
Technologies as a leading provider of defense electronics products and
services with a run rate in excess of $2.5 billion in annual revenues and a
major role in armed forces modernization, personnel mobility and O&M
support. An important milestone in the growth of our company, this
acquisition will strengthen our strategic position and expand our program
participation and platform applications with all of the military services,
while providing new opportunities for growth in intelligence and homeland
security markets."

         Gerald A. Potthoff, vice chairman and chief executive officer of
Engineered Support Systems, added, "This is another exciting chapter for
ESSI, taking our company to the next level and delivering excellent value to
our stockholders. DRS Technologies is a highly-regarded presence in defense
technology, and with ESSI will become a sizable,

                                  - more -



diversified industry competitor, strategically positioned for exciting
growth opportunities. We believe the combination will benefit customers,
business associates, investors and employees. This transaction undoubtedly
will bolster the combined company's ability to accomplish its mission to
support the military's near-term force modernization and emerging
transformation initiatives."

       DRS Technologies said the acquisition offers opportunities to
leverage synergies and to accomplish several objectives. It is expected to:

       o Enhance DRS's market leadership position, adding to its critical
         mass and extensive array of products and significantly expanding
         the company's logistics support and services business;

       o Complement the company's customer base, strengthening positions
         with the U.S. Army, Air Force and Navy, intelligence agencies,
         prime contractors and international military forces;

       o Increase access to government funding budgeted within the procurement
         and O&M accounts;

       o Increase content on military programs, including those related to
         power generation, conversion, distribution and power management;
         electro-optical and infrared (EO/IR) technology; vehicle
         diagnostics and automated test equipment; and radar systems;

       o Enhance technology capabilities in intelligence through satellite
         communications (SATCOM)/wireless services and systems integration;

       o Broaden DRS's homeland security capabilities;

       o Diversify the company's program base so that no single product or
         program accounts for more than 3 percent of annual revenues and the
         ten largest programs account for approximately 20 percent; and

       o Generate earnings accretion and strong free cash flow.

TRANSACTION DETAILS

         Under the terms of the acquisition, each share of ESSI common stock
will be converted into the right to receive a combination of $30.10 in cash
and a portion of a share of DRS common stock valued at $12.90, provided that
the average closing price of DRS's common stock prior to the closing of the
transaction is between $46.80 and $57.20. The exchange ratio will increase
or decrease in proportion to the average closing price of DRS's common
stock. A collar provides that the exchange ratio will not exceed 0.2756 of a
share nor be less than 0.2255 of a share of DRS common stock.

         The cash portion of the acquisition, together with the debt of ESSI
to be refinanced, will aggregate approximately $1.49 billion at closing.
Total consideration for the acquisition, including an estimated $88.3
million of ESSI's debt to be refinanced at closing, is approximately $1.97
billion.

                                  - more -





         DRS expects to finance the cash portion of the acquisition by
utilizing existing excess cash on hand and through a combination of bank
borrowings and the issuance of debt securities.

          "We have constructed an offer that balances prudent financing with
our objective to deliver earnings accretion and top-line growth," said
Richard A. Schneider, DRS Technologies' executive vice president and chief
financial officer. "This approach is consistent with our experience on the
acquisition of Integrated Defense Technologies in 2003, whereby we delivered
on our commitment to deleverage net debt to earnings before income taxes,
depreciation and amortization (EBITDA) from 4.0 to 2.9 in two years and
achieve meaningful earnings accretion and growth."

         The transaction is expected to close before the end of DRS's fiscal
2006 and is subject to customary regulatory approvals and other closing
conditions, including approval by DRS's and ESSI's stockholders at
respective special stockholder meetings.

         Bear, Stearns & Co. Inc. is serving as financial advisor to DRS on
the transaction and has provided committed financing necessary for DRS to
consummate the acquisition and for ongoing working capital needs. Merrill
Lynch & Co., Inc. also is serving as financial advisor to DRS for the
purpose of rendering a fairness opinion. Lehman Brothers Inc. is serving as
financial advisor to ESSI on the transaction.
