Item 5.           Other Events.

                  On April 16, 2003, Engineered Support Systems, Inc. (the
                  Company) completed the sale of its wholly-owned
                  subsidiary, Engineered Specialty Plastics, Inc. (ESP), to
                  a private equity group for approximately $7.4 million,
                  comprised of cash and a mortgage note payable to the
                  Company, plus certain working capital adjustments and
                  contingent consideration based upon ESP's future revenues.
                  ESP, which comprised all of the Company's Plastic Products

                  disposal of ESP of $4.2 million and does not anticipate a
                  significant change in this estimated loss as a result of
                  the consummation of this transaction.

                         ENGINEERED SUPPORT SYSTEMS
                   COMPLETES DIVESTITURE OF PLASTICS UNIT

         ST. LOUIS, MO, APRIL 21, 2003 - ENGINEERED SUPPORT SYSTEMS, INC.
(Nasdaq: EASI) announced that it has completed the sale of all the
outstanding stock of its Plastic Products business segment to a private
equity group for approximately $7.4 million, plus contingent consideration.
The Company had previously announced its intentions to dispose of this
business unit in May of 2002. Since that time, the Plastics segment had been
treated as a discontinued operation in the Company's financial statements,
according to GERALD E. DANIELS, VICE CHAIRMAN AND CHIEF EXECUTIVE OFFICER.

Terms of the transaction include aggregate consideration of $7.4 million
comprised of cash and a mortgage note payable to the Company, certain
adjustments dependent upon the level of working capital as of the closing
date, plus contingent consideration based upon its future revenues. In
conjunction with the intended disposition of this business, during 2002,
Engineered Support recorded an after-tax provision of approximately $4.2
million related to the write-down of property and equipment to its estimated
net realizable value. The Company does not expect to record any further
significant loss provision in connection with the consummation of this
transaction.

The Company's Plastic Products segment consisted of two wholly-owned
subsidiaries, Engineered Specialty Plastics, Inc., a manufacturer of
injection-molded resin products, and Lifetime Faucets, Inc., a provider of a
propriety line of non-metallic faucets, both primarily for commercial
customers in the south-central U.S. For its most recently completed fiscal
year, the Company's Plastic Products segment reported revenues of $17.6
million.

Daniels commented, "I am pleased to report that the planned disposition of
our non-core, commercial plastics operation has been completed, particularly
at a time of difficult market conditions in the injection-molded plastics
industry. Having endured three plus years of depressed revenues and marginal
financial performance in our commercial Plastics segment, we believe that
our shareholders will be better served by the redeployment of both the
monetary and human capital from this area to our core defense business
units. In the meantime, we thank the management and employees of the
Plastics segment for persevering through the uncertainty of the sale process
and wish the new ownership group well in its future endeavors."

The Company will use the cash portion of the sales proceeds to reduce its
outstanding bank indebtedness.

Engineered Support Systems, Inc. is a diversified supplier of high-tech,
integrated military electronics, support equipment and logistics services
for all branches of America's armed forces and certain foreign militaries.
The Company also serves a variety of commercial customers. For more
