ST. LOUIS, MO. - DECEMBER 14, 2004 - ENGINEERED SUPPORT SYSTEMS, INC.
(Nasdaq: EASI) reported record net earnings from continuing operations of
$21.3 million, or $.76 per diluted share, for the quarter ended October 31,
2004 compared to $13.9 million, or $.52 per diluted share, for the same
period last year. Net revenues also set an all-time quarterly record at
$256.4 million, up 51% over the $170.3 million for the fourth quarter of
last year. Fourth quarter net revenues were also substantially above the
Company's forecasted levels for the period as work on certain contracts was
accelerated to meet customer requirements. Solid revenue growth was
experienced in both the Support Systems and Support Services business
segments with overall organic revenue growth for the quarter of 49%,
according to GERALD A. POTTHOFF, VICE CHAIRMAN, CEO AND PRESIDENT.

Fourth quarter operating income from continuing operations of a record $33.7
million was 44% above the $23.4 million reported for the same quarter in the
prior year. As a percentage of net revenues, operating income from
continuing operations was 13.1% for the current quarter as compared to 13.7%
for the fourth quarter of fiscal 2003. However, it should be noted that the
current quarter includes a pre-tax charge of $5.0 million ($4.2 million of
which was non-cash), related to the departure of its previous CEO in August
of this year. Earnings before interest, income taxes, depreciation and
amortization (EBITDA) from continuing operations for the current quarter
climbed 46% to a record $37.1 million, or 14.5% of net revenues.

Net income from continuing operations for the fourth quarter advanced 53% to
a record $21.3 million (8.3% of net revenues) compared to $13.9 million
(8.2% of net revenues) last year. Excluding the after-tax severance costs
noted above, net income from continuing operations totaled $24.4 million
(9.5% of net revenues) in the current quarter. Contributions from increased
net revenues in 2004 drove earnings higher during the period as compared to
the prior year.



                                     2

Potthoff commented, "The fourth quarter's results capped a truly exceptional
year in 2004. Our financial performance was outstanding with quarterly
revenues topping the $250 million mark for the first time in our history
with strong profit margins posted across the board. This combined to drive
quarterly earnings to record levels once again. We expect to continue this
momentum forward into 2005 particularly with the inclusion of our recently
announced acquisition of satellite communications network provider Spacelink
International, which we will discuss in more detail during our conference
call later this morning."

     o   FISCAL 2004 REVENUES UP 54% TO $883.6 MILLION

     o   NET EARNINGS FROM CONTINUING OPERATIONS GREW 75% TO $75.9 MILLION
         FOR YEAR

     o   FISCAL 2004 EPS FROM CONTINUING OPERATIONS UP 62% TO $2.72

For the year ended October 31, 2004, net revenues grew by 54% to a record
$883.6 million compared to $572.7 million last year. Fiscal 2004 operating
income from continuing operations of $123.3 million and EBITDA from
continuing operations of $137.6 million progressed by 70% and 69%,
respectively, over fiscal 2003 levels. Net income from continuing operations
for the year totaled a record $75.9 million, or $2.72 per diluted share,
compared to $43.3 million, or $1.68 per diluted share, for fiscal 2003.

Reflecting its strong earnings performance, the Company generated record
free cash flow (cash flow from operations less capital expenditures) of
$57.4 million during fiscal 2004 with a substantial portion of that
occurring in the fourth quarter as anticipated. The Company expects that its
cash flow metrics will improve still further in fiscal 2005 as existing
working capital levels related to contracts currently in process are
reduced. The Company employed its cash flow to repay over $70 million in
bank debt during the year and had some $33 million of cash on the balance
sheet as of October 31, 2004. Engineered Support will utilize cash on hand
plus borrowings under its existing line of credit to fund its recently
announced acquisition of Spacelink International LLC.

Potthoff commented, "Through the focused efforts of our eleven operating
subsidiaries in serving the demanding needs of our military, intelligence
and industrial customers, we posted yet another record year for revenues,
operating profit and net earnings - marking a dozen years in a row of
year-over-year growth. Net revenues approached the $900 million level in
2004 while earnings and margins continued their impressive track record and
cash flow generation remained robust.

Certainly, selected acquisitions have greatly expanded our existing
manufacturing and service capabilities over the years, but, more critically,
our ability to then leverage our collective business development and
organizational resources has been a huge part of our enduring success as a
company. The overriding commitment of our management and employees to
function as a cohesive team is what allows our entrepreneurial business
model to flourish. Growing our business is indeed important, but effectively
managing that growth is what will allow Engineered Support Systems to
achieve our goals as an organization. As we continue on our strategic path
to provide superior sustainment solutions to those who serve in the changing
world that we are faced with today, the need for teamwork has never been
greater."

BUSINESS SEGMENT RESULTS

For the fourth quarter, the Support Systems segment reported net revenues of
$138.0 million compared to $99.4 million (prior to the elimination of
inter-segment revenues in each period) for the same quarter in the prior
year, a 39% increase. Organic revenue growth for the segment totaled an
impressive 36% with additional work on several Support Systems programs
during the quarter, while the inclusion of two smaller acquisitions,
Engineered Environments and Pivotal Power, contributed as well. Programs
with the largest revenue gains during the quarter primarily included the
Manportable Surveillance and Target Acquisition Radar (MSTAR) being used for
a variety of perimeter security applications, M1000 Heavy Equipment
Transporters which are being refurbished after their recent battlefield
deployment in Iraq, and inter-segment production work on vehicle uparmor
kits being performed for the Support Services segment. Segment revenue
growth was partially offset by reduced work on the 60-K Tunner Aircraft
Cargo Loader contract as production work on that contract winds down in
mid-2005.

Quarterly operating income for the Support Systems segment climbed to $21.3
million (15.5% of segment revenues) compared to $18.1 million last year.
This included the allocation of $3.1 million of the one-time severance costs
noted above. Incremental revenues and related gross profit contributions
plus cost savings realized under the Company's facility rationalization
initiatives led to the overall improved results for the Support Systems
segment.

Net revenues of the Support Services segment climbed to $138.7 million
compared to $72.5 million (prior to the elimination of inter-segment
revenues in each period) for the fourth quarter of 2003, due to significant
internal growth in several business areas. This marks the first period in
which quarterly revenues for the Services segment outpaced those of the
Company's manufacturing-based segment and signifies the rapid organic growth
potential in the Services area. Sizeable year-over-year revenue increases
were noted on several existing programs, including the DPGDS power
generation system and satellite telecommunications support, while newer
programs such as vehicle uparmor kits at Radian, ESSIbuy's U.S. Army depot
support efforts and work under TAMSCO's Rapid Response (R2) contract
contributed significantly during the period as well.

Quarterly operating income for the Support Services segment rose to $12.3
million (8.9% of segment revenues) compared to $5.2 million last year.
Services segment profit margins increased as a result of contributions from
the increase in revenues noted above. This included the allocation of $1.9
million of the one-time severance costs noted above.

Potthoff stated, "The synergy among our assembled business units as well as
between our Systems and Services segments really gained momentum during
2004. This spirit of collaboration and teamwork has been displayed by our
people in many ways - from the successful launch of our vehicle uparmor
program by Radian and SEI; to the use of the R2 contract as a vehicle for
new logistics support work for ESSIbuy or for incremental Systems production
orders; to the array of internal resources brought to bear to recently win a
key development contract, AMMPS, for next generation power systems. The list
goes on and on. As we move forward, we will continue to leverage the
collective capabilities of the Engineered Support family for the benefit of
our customers, employees and shareholders in delivering responsive,
innovative solutions to the marketplace."



                                     4

ENTERED ORDERS AND BACKLOG

On the strength of $190 million in bookings during the fourth quarter,
entered orders for 2004 totaled a record $938 million, or 43% above the
level of the prior year, yielding a book-to-bill ratio of 1.06 to 1. These
orders resulted in a year-end funded contract backlog of a record $588
million and a total backlog including primarily unfunded options on
long-term production contracts of $1.4 billion. It should be noted that
unfunded backlog excludes any potential business under many of the Company's
multi-year services contracts, including its $2.9 billion ceiling Rapid
Response contract with the U.S. Army.

ACQUISITION OF SPACELINK INTERNATIONAL

On December 9, 2004, the Company announced that it had entered into a
definitive agreement to purchase Spacelink International, LLC (Spacelink)
for total initial consideration of $150.5 million in cash and common stock.
Spacelink, based in Dulles, Virginia, is involved in the design,
integration, operation and maintenance of deployed satellite and wireless
networks for the U.S. Department of Defense (DoD), the U.S intelligence
community and other forward deployed federal agencies and multinational
organizations worldwide. Spacelink has grown rapidly in recent years,
expecting to post revenues for calendar year 2004 of approximately $95
million, with profit margins in the mid-teens. The acquisition of Spacelink
will be immediately accretive to earnings once the transaction closes within
the next sixty days pending customary closing conditions and regulatory
approval. Engineered Support will utilize cash on hand as well as
availability under its existing $200 million revolving credit facility to
fund the $138.5 million cash portion of the purchase price and will issue
approximately 228,000 unregistered shares of common stock worth
approximately $12 million (as determined based upon average closing share
prices for the last thirty trading days prior to the date of the agreement).

Commenting on the pending acquisition, Potthoff stated, "Spacelink is an
excellent complement to our military telecommunications support business at
TAMSCO, and it will solidify ESSI's position as a major player in this
increasingly vital area of global U.S. military operations. Any time our
forces deploy, they must provide for literally every facet of their basic
infrastructure, including food, water, fuel, power, air conditioning,
heating, transport, security as well as satellite telecommunications
capabilities, in order to sustain themselves - to sustain the fight so to
speak. As a leader in the military sustainment arena, Engineered Support
increasingly provides products, services and support that fulfill our
forces' many needs in these essential areas. Spacelink's close customer
relationships, variety of contract vehicles and demonstrated track record
over the past ten years in delivering turn-key satellite network solutions
represent a formidable addition to the ESSI family."

OUTLOOK FOR 2005

Potthoff concluded, "Including the post-acquisition financial results of
Spacelink, expected to close early in the second quarter, we are forecasting
revenues at this point of $975 million to $985 million for fiscal 2005,
excluding any additional potential acquisitions. From this solid revenue
base, we expect to derive fiscal 2005 earnings of $3.10 to $3.15 per share -
roughly an increase of 15% over last year.



                                     5

Obviously, the heightened state of U.S. military involvement around the
globe, particularly in Southwest Asia, remains a key catalyst for our
Company. The likelihood of supplemental appropriations by Congress to
support ongoing operations as well as funding for the recapitalization of
military equipment readiness levels provide fertile new business initiatives
for ESSI. As a flexible, capability-based defense contractor, Engineered
Support Systems is indeed well positioned to quickly respond to our
customers' needs on a variety of fronts and stands ready to respond. We are
prepared to update our financial forecast in the coming months should any of
a number of emerging business development opportunities transpire."
