                   FOURTH QUARTER AND FISCAL 2005 RESULTS


     o   QUARTERLY REVENUES UP 2% TO $262.3 MILLION; EXCEED $1 BILLION FOR
         YEAR

     o   QUARTERLY NET EARNINGS FROM CONTINUING OPERATIONS UP 12% TO $24.0
         MILLION

     o   FOURTH QUARTER EPS FROM CONTINUING OPERATIONS OF $.55 VS. $.51 IN
         2004

         ST. LOUIS, MO. - DECEMBER 13, 2005 - ENGINEERED SUPPORT SYSTEMS,
INC. (Nasdaq: EASI) reported record quarterly net earnings from continuing
operations of $24.0 million, or $.55 per diluted share, for the fourth
quarter ended October 31, 2005, compared to $21.3 million, or $.51 per
diluted share, for the fourth quarter of last year. Net revenues increased
2% to $262.3 million compared to the fourth quarter of last year.

Fourth quarter operating income from continuing operations of $38.1 million
increased 13% above the $33.7 million reported for the fourth quarter of the
prior year. As a percentage of net revenues, operating income from
continuing operations was 14.5% for the most recently completed quarter as
compared to 13.1% for the fourth quarter of 2004. Reported operating results
for the fourth quarter of 2005 included legal, accounting and other costs
totaling $1.7 million, or $.02 per diluted share after-tax, related to the
Company's pending merger with DRS Technologies, Inc. (NYSE: DRS), a global
provider of defense electronics products and systems, which was announced on
September 22, 2005. Pending required shareholder and regulatory approvals,
the merger transaction is expected to be completed during the first calendar
quarter of 2006.

The Company's operating results for the fourth quarter of 2005 were also
negatively impacted by temporary production delays on its Deployable Power
Generation and Distribution System (DPGDS) program. However, the program was
returned to full rate production during the latter half of the most recently
completed quarter as previously reported by the Company. Revenue
contributions from the DPGDS program totaled $12.2 million and $37.9
million, respectively, for the fourth quarters of 2005 and 2004. It should
also be noted that the fourth quarter's results in the prior year included
an after-tax charge of $3.1 million, or $.07 per diluted share, related to
the departure of a former executive in August of 2004.

Quarterly net revenues for the fourth quarter of 2005 also were impacted by
variations at existing business units primarily due to the completion of
certain long-term production programs during the current year. The Company's
most recently acquired subsidiaries, Prospective Computer Analysts (PCA),
Spacelink International, LLC (Spacelink) and Mobilized Systems, Inc. (MSI)
added a combined $29.5 million of incremental revenues during the fourth
quarter of 2005.







                                     2


Net income from continuing operations for the fourth quarter advanced 12% to
$24.0 million (9.1% of net revenues) compared to $21.3 million (8.3% of net
revenues) for the fourth quarter of the prior year. Profit contributions in
the fourth quarter of 2005 from the Company's most recently acquired
businesses combined with the inclusion of the aforementioned one-time
severance costs in the fourth quarter of the prior year were primarily
responsible for the increase in reported earnings for the most recently
completed quarter. In addition, as a result of the Company's ongoing income
tax savings initiatives, its overall effective income tax rate was reduced
to 37.5% for fiscal 2005 during the fourth quarter generating a cumulative
benefit of $0.5 million, or $0.01 per share during the period.

As reported previously, during the second quarter of 2005, the Company
settled its arbitration with the purchasers of its discontinued Plastics
business unit disposed of in April 2003, resulting in the modification of
the terms of the Company's note receivable from the buyers. Due to these
developments, the Company recorded an after-tax, non-cash charge of $1.0
million, or $.02 per diluted share, during the second quarter of 2005 to
establish a valuation allowance for potential uncollectibility of the
restructured note. During the fourth quarter of 2005, the Company was
notified that the buyers of its discontinued Plastics unit were insolvent.
Accordingly, the Company recorded an additional after-tax, non-cash charge
of $1.0 million, or $.02 per diluted share, in the fourth quarter of 2005 to
establish a full valuation allowance for the note. These charges are
reflected within the discontinued operations section of the Company's
statements of income in the financial information accompanying this release.

As a result of the foregoing, net income for the fourth quarter of 2005
totaled $23.0 million compared to $21.3 million for the fourth quarter of
the prior year resulting in diluted earnings per share of $.53 and $.51 for
these respective periods.

O        FISCAL 2005 REVENUES UP 15% TO $1.02 BILLION

O        NET EARNINGS FROM CONTINUING OPERATIONS GREW 15% TO $87.2 MILLION
         FOR YEAR

O        FISCAL 2005 EPS FROM CONTINUING OPERATIONS OF $2.02 VS. $1.82 FOR
         FISCAL 2004

O        CASH FLOW FROM CONTINUING OPERATIONS OF $107.8 MILLION FOR FISCAL 2005

For the year ended October 31, 2005, net revenues grew by 15% to a record
$1.02 billion compared to $883.6 million last year. Fiscal 2005 operating
income from continuing operations of $141.4 million from continuing
operations increased by 15% compared to fiscal 2004. Net income from
continuing operations for 2005 totaled a record $87.2 million, or $2.02 per
diluted share, compared to $75.9 million, or $1.82 per diluted share, for
fiscal 2004.

Revenue contributions from the three business units acquired during 2005
totaled a combined $85.1 million, with organic revenue growth accounting for
$49.7 million of the year-over-year increase.

The Company generated record cash flow from continuing operations of $107.8
million during 2005 compared to operating cash flow of $66.6 million in the
prior year. Higher net earnings and improved working capital management were
responsible for the increase in free cash flow year over year.

BUSINESS SEGMENT RESULTS

For the fourth quarter of 2005, the Support Systems segment reported net
revenues of $121.4 million compared to $138.0 million (prior to the
elimination of inter-segment revenues in each period) for the fourth quarter
of the prior year, a 12% decrease. Overall organic revenues for the segment
declined by 19%, partially offset by the inclusion of PCA and MSI which
contributed net revenues of $9.4 million during the most recently completed
quarter. During the fourth quarter of 2005, the segment experienced
significantly reduced revenues on the Tunner 60-K Aircraft Cargo Loader as
the production phase of that long-term program wound down during the first
half of the year. In addition, the segment had reduced deliveries of MSTAR
perimeter security systems in the most recently completed quarter as a large
base security subcontract with Northrop Grumman was completed during the
latter portion of fiscal 2004. The Systems segment also performed less
intersegment work on the production of vehicle add-on armor kits in 2005
compared to the fourth quarter of 2004. Additional production activity
involving the refurbishment of M1000 Heavy Equipment Transporters and
revenue gains at various other business operations within the segment
partially offset these revenue decreases for the quarter.

Fourth quarter operating income for the Support Systems segment was $20.6
million (17.0% of segment net revenues) compared to $21.3 million (15.5% of
segment net revenues) for the fourth quarter of last year. The decrease in
segment net revenues and the related gross profit contributions led to the
overall lower operating profit for the Support Systems segment. Segment
profit margins in the fourth quarter of the prior year were negatively
impacted by the allocation of $3.1 million in pre-tax severance costs
related to the departure of a former executive in August 2004.

Net revenues of the Support Services segment for the fourth quarter of 2005
increased 3% to $152.8 million compared to $148.8 million (prior to the
elimination of inter-segment revenues in each period) for the fourth quarter
of 2004. This was primarily due to the inclusion of Spacelink in 2005, which
contributed net revenues of $20.2 million for the most recently completed
quarter. The resulting decline in quarter-over-quarter Services segment
revenues at existing business units reflects reduced revenues on the DPGDS
program in 2005 as noted above combined with the fulfillment of orders for
add-on vehicle armor during the most recently completed quarter. This trend
was partially offset by increased revenues for satellite telecommunications
support work and related areas.

Fourth quarter operating income for the Support Services segment was $17.5
million (11.4% of segment net revenues) compared to $12.3 million (8.3% of
segment net revenues) last year. Services segment operating profit levels
for the most recently completed quarter reflect the contribution from
Spacelink as well as overall improved profit margins within the segment.
Segment profit margins in the fourth quarter of the prior year were
negatively impacted by the allocation of $1.9 million in pre-tax severance
costs related to the departure of a former executive in August 2004 as noted
above.

ENTERED ORDERS AND BACKLOG

Bookings during the fourth quarter were $346 million while entered orders
for 2005 totaled a record of nearly $1.1 billion, yielding a book-to-bill
ratio for the year of 1.04 to 1. These orders resulted in a record year-end
funded contract backlog of $690 million and a total backlog including
primarily unfunded options on long-term production contracts of $2.2
billion.
