which brokerage houses, other institutions, nominees or fiduciaries
customarily charge to forward the aforementioned material to the

                        RIGHT OF REVOCATION

    Any shareholder executing a proxy for the meeting may revoke the
proxy by written notice of revocation delivered or mailed to, and
received by, the Secretary of the Company at 201 Evans Lane, St.
Louis, Missouri 63121 prior to the time the proxy is voted.

                           VOTING RIGHTS

    The shareholders of record at the close of business on January
16, 2004 are entitled to vote at the 2004 Annual Meeting of the
Shareholders. Proxies properly executed by the Company's
shareholders of record on January 16, 2004 will be voted as
specified on the proxy and will be voted on all business to be voted
upon at the

                                 2





Annual Meeting of the Shareholders and any adjournment thereof.
Generally, each share is entitled to one vote. However, in the
election of directors, cumulative voting applies in which each
shareholder has the right to cast as many votes as equals the number
of shares held by that shareholder multiplied by the number of
directors to be elected. Each shareholder may also cast the whole
number of votes for one nominee or distribute them among some or all
nominees. If authority is withheld to vote for one or more
individual nominees on the proxy, the total cumulative votes will be
allocated equally among the remaining nominees. As of January 16,
2004, there were 25,864,074 shares of common stock outstanding and
entitled to vote.

                           VOTE REQUIRED

    A quorum is required for the transaction of business at the
Annual Meeting. A majority of the issued and outstanding shares
entitled to vote at the Annual Meeting will constitute a quorum.
Shares represented by properly executed proxies, including proxies
which direct that the shares be voted to abstain or withhold a vote
on a matter, will be counted for purposes of determining whether a
quorum exists. Broker non-votes will be counted for purposes of
determining whether a quorum exists only if such shares are voted on
a matter presented at the meeting. A broker non-vote occurs when a
nominee holding shares for a beneficial owner does not vote a
particular proposal because the nominee does not have discretionary
voting power with respect to that item and has not received
instructions from the beneficial owner. Every decision of a majority
of such quorum shall be valid as a corporate act unless a larger
vote is required under the Statutes of Missouri.

    At all elections of directors of the Company, each shareholder
shall have the right to cast as many votes in the aggregate as shall
equal the number of voting shares so held by him or her in the
Company, multiplied by the number of directors to be elected at such
election; and each shareholder may cast the whole number of votes
either in person or by proxy for one nominee or distribute them
among two or more nominees. Approval of the Engineered Support
Systems, Inc. 2004 Stock Option Plan and 2004 Non-Executive Stock
Option Plan each requires a vote of holders of a majority of shares
represented at the Annual Meeting.

                            PROPOSAL ONE
                       ELECTION OF DIRECTORS

    The by-laws of the Company provide for staggered terms for the
Directors. The election of the Directors for staggered terms
maintains management continuity and discourages undesirable mergers,
tender offers, proxy contests and the ill-favored exertion of
control by a large block of common stock.

    The nominees, Gerald E. Daniels, Ronald W. Davis, William H. T.
Bush, S. Lee Kling, General Crosbie E. Saint (U.S. Army, Retired) and
Earl W. Wims, Ph.D., are each proposed to be elected for a three (3)
year term. The shares of common stock represented by properly executed
proxies will be voted in accordance with the

                                 4





instructions contained in the proxy or, if no instructions are given,
for each of the nominees. All nominees have consented to be named and
to serve, if elected. If any nominee is unable to serve (which
management has no reason to expect), the individuals named in the
proxy intend to vote for the balance of those named and for a
substitute nominee, if management recommends a vote for the substitute
nominee.

    THE BOARD RECOMMENDS THE SHAREHOLDERS VOTE "FOR" THE SIX (6)
NOMINEES TO THE BOARD.

    The following table sets forth, for each director and nominee,
his principal occupation, the year in which his current term ends,
the year in which he was first elected as a director and his age.

                REPORT OF THE COMPENSATION COMMITTEE
                     ON EXECUTIVE COMPENSATION

    The following report is provided by the Compensation Committee.
The Committee supervises the Company's Executive Compensation
Program ("Program") and is directly responsible for compensation
actions affecting the Chairman and other executive officers of the
Company and its subsidiaries. The Committee met three (3) times in
fiscal year 2003.

THE EXECUTIVE COMPENSATION PHILOSOPHY

    The Program is designed and managed to link executive
compensation to four basic objectives: Company performance,
shareholder return, individual performance and competitive position.
With respect to competitive position, the Program is designed to pay
competitive compensation so the Company is able to attract and
retain highly qualified executives. In determining competitive
compensation practices, the Committee frequently utilizes
information about other relevant companies' compensation levels, as
well as information from qualified compensation consultants.

    The Program uses overall Company performance in determining
compensation levels and compensation changes. The Committee
considers the Company's overall performance in meeting both
short-term and long-term objectives and considers the Company's
operating achievements in typical performance measures such as
earnings, cash management and contract backlog. The Committee also
considers the Company's progress towards long-term strategic
objectives that cannot be easily quantified.

    The Program also links the interests of the Company's executives
with the interests of its shareholders. This is accomplished by
allocating a portion of executive compensation to performance-based
equity compensation.

THE EXECUTIVE COMPENSATION PROGRAM

    The Program consists of three basic elements: base salary,
incentive bonus compensation and performance-based equity
compensation. Base salaries are reviewed annually. Salary changes
reflect overall Company performance, pay competitiveness and
individual performance.

    A substantial portion of each executive's annual cash
compensation is tied to the Company's performance through incentive
bonus compensation. The goals of this element of compensation are to
focus the attention of executives on profits, continued growth,
increased efficiency and teamwork, as well as to improve the
Company's ability to attract and retain outstanding executive
talent.

    The Committee determines the annual incentive bonus payment for
each executive at the end of each fiscal year based on the Company's
performance in important areas such as earnings, contract backlog
and cash management. The Committee also considers the executive's
individual contribution to the Company's performance and the
executives contributions to the Company's progress towards long-term
strategic objectives. Certain executives do receive minimum bonus
payments.

    To ensure that management's interests are directly tied to
shareholder return, a substantial portion of an executive's total
compensation is equity compensation. To place emphasis on
shareholder return, the Company, pursuant to shareholder approval,
has adopted various Stock Option Plans ("Option Plans"). As of
October 31, 2003, there were 4,432,498 shares reserved for issuance
upon the exercise of outstanding options or future issuance under
the Option Plans. All options granted to date have been awarded at
an exercise price equal to the fair market value of the stock on the
date of the award. The Option Plans are administered by the
Compensation Committee and option awards are made subjectively based
upon the evaluations of the executive's past and anticipated future
contribution to the Company's performance.

FISCAL YEAR 2003 EXECUTIVE OFFICER COMPENSATION

    In determining the fiscal year 2003 performance compensation
payments for the Chairman and Chief Executive Officer and the other
executive officers, the Committee considered the Company's operating
performance and return to shareholders. Fiscal year 2003 net
revenues from continuing operations, net income from continuing
operations and book value increased 40%, 56% and 46%, respectively,
over fiscal year 2002. Share price increased 125% from $24.44 per
share on December 31, 2002, as adjusted for the three-for-two stock

                                 10





split effected by the Company on October 31, 2003, to $55.06 per
share on December 31, 2003. The Committee also considered each
executive's contribution to the Company's performance.

    Based on the subjective evaluation of the above factors, the
Committee approved the base annual salary of $1,000,000 and an
incentive bonus payment of $1,500,000 for the Company's Chairman.
Based on the subjective evaluation of the above factors, the
Committee also approved the base annual salary of $600,000 and an
incentive bonus payment of $262,500 for the Vice Chairman and Chief
Executive Officer, the base annual salary of $500,000 and an
incentive bonus payment of $375,000 for the President and Chief
Operating Officer; the base annual salary of $400,000 and an
incentive bonus payment of $300,000 for the Vice Chairman and Chief
Financial Officer; and, the base annual salary of $350,000 and an
incentive bonus payment of $262,500 for the President, Business
Development. The Committee also awarded options for 0, 150,000,
15,000, 15,000 and 15,000 shares under the Option Plans to Mr.
Shanahan, Sr., Mr. Daniels, Mr. Potthoff, Mr. Gerhardt and Mr.
Davis, respectively.

    The Company does have employment agreements with its Chairman
and the other executive officers. These employment agreements are
discussed in the next section of this proxy statement.

SUMMARY

    Through the design and management of the Executive Compensation
Program, as described above, the Committee believes total
compensation of the Company's executives is linked directly to
Company performance, individual performance and shareholder return.
The Committee will continue to emphasize performance-based and
stock-based compensation that is consistent with individual
performance and that links management and shareholder interests. The
Committee concludes that the Company's performance and the
competitive market warrant the compensation package approved for Mr.
Shanahan, Sr. and the other executive officers.

reimbursed for expenses associated with performing his duties on
behalf of the Company. The Company has a split dollar life insurance
arrangement with Mr. Davis similar to the agreement with Mr.
Shanahan.

    Pending clarification of certain provisions of the
Sarbanes-Oxley Act of 2002, the Company has suspended payment of
premiums with respect to the split dollar life insurance agreements
for Mr. Shanahan and for those other officers with split dollar life
insurance agreements with the Company. In accordance with the terms
of the insurance policies, the insurance carriers have applied
available cash values in payment of premiums otherwise payable in
2003.

                            PROPOSAL TWO

            APPROVAL OF ENGINEERED SUPPORT SYSTEMS, INC.
      2004 STOCK OPTION PLAN AND RESERVATION OF 350,000 SHARES
                    OF COMMON STOCK TO THE PLAN

    The Company is seeking shareholder approval of the Engineered
Support Systems, Inc. 2004 Stock Option Plan for officers, key
employees and consultants of the Company, and the reservation of
350,000 shares of Engineered Support Systems, Inc. common stock for
future issuances under the plan which, if approved, the Company
proposes to implement after March 2, 2004. The purpose of the plan
is to motivate officers, key employees and consultants by creating
an incentive for them to remain in the employ of the Company and to
work for the achievement of the Company's strategic objectives. To
accomplish this purpose, the Compensation Committee may award
so-called "non-incentive" stock options to purchase the Company's
common stock to eligible officers, key employees and consultants as
earned by their performance.

    The complete text of the plan is attached as Appendix C to this
proxy statement. The following summary of certain provisions of the
plan is qualified by reference to the text of the plan.

    The Compensation Committee shall administer the plan and, in
connection therewith, shall have full power to grant awards,
construe and interpret the plan, establish rules and regulations and
perform all other acts deemed reasonable and proper to administer
the plan, subject to the provisions of the plan.

    The options shall be granted at the fair market value of the
Company's common stock on the date awarded. All shares subject to
options may be awarded to any one individual in any calendar year.
The closing price of the Company's common stock as of January 16,
2004 was $49.79 per share. The options expire five (5) years from
the date of grant, unless terminated sooner due to the termination
of service or death of the optionee. The plan will expire on October
31, 2009 unless extended or sooner terminated by the Company's

2004 NON-EXECUTIVE STOCK OPTION PLAN AND RESERVATION OF 350,000 SHARES
                    OF COMMON STOCK TO THE PLAN

    The Company is seeking shareholder approval of the Engineered
Support Systems, Inc. 2004 Non-Executive Stock Option Plan for key
employees and consultants of the Company, and the allocation of
350,000 shares of Engineered Support Systems, Inc. common stock for
future issuance under the plan which, if approved, the Company
proposes to implement after March 2, 2004. The purpose of the plan
is to motivate key employees and consultants, by creating an
incentive for them to remain in the employ, or consultancy, of the
Company and to work for the achievement of the Company's strategic
objectives. To accomplish this purpose, the Compensation Committee
may award so-called "non-incentive" stock options of the Company's
common stock to eligible key employees and consultants as earned by
their performance.

    The complete text of the plan is attached as Appendix D to this
proxy statement. The following summary of certain provisions of the
plan is qualified by reference to the text of the plan.

    ANY EMPLOYEE OR CONSULTANT OF THE COMPANY SHALL BE ELIGIBLE TO
PARTICIPATE IN THE PLAN, EXCEPT NO "OFFICER" OF THE COMPANY AS THAT
TERM IS DEFINED IN RULE 16a-1 OF THE SECURITIES EXCHANGE ACT OF
1934, AS AMENDED, OR DIRECTOR OF THE COMPANY SHALL BE ELIGIBLE TO
PARTICIPATE IN THE PLAN. The Compensation Committee shall administer
the plan and, in connection therewith, shall have full power to
grant awards, construe and interpret the plan, establish rules and
regulations and perform all other acts deemed reasonable and proper
to administer the plan, subject to the provisions of the plan.

    The options shall be granted at the fair market value of the
Company's common stock on the date awarded. The closing price of the
Company's common stock as of January 16, 2004 was $49.79 per share.
The options expire five (5) years from the date of grant, unless
terminated sooner due to the termination of service or death of the
optionee. The plan will expire on October 31, 2009 unless extended
or sooner terminated by the Company's Board. In case of death, the
beneficiary of the deceased will have the right for six (6) months
after the date of death to exercise the options. The options granted
may not be repriced at any time and are not transferable or
assignable. For federal income tax purposes, no income will be
realized by a participant in the plan upon the grant of an option,
and the Company will not be entitled to a deduction at that time.
Upon the exercise of the option, the excess of the fair market value
of the stock on the date of exercise over the purchase price is
ordinary income to the holder as of the date of exercise. The
Company generally will be entitled to a deduction equal to the
excess amount in the year of exercise.

    THE BOARD RECOMMENDS THE SHAREHOLDERS VOTE "FOR" THE APPROVAL OF
THE ENGINEERED SUPPORT SYSTEMS, INC. 2004 NON-EXECUTIVE STOCK OPTION

   POLICY REGARDING THE APPROVAL OF INDEPENDENT AUDITOR PROVISION
                  OF AUDIT AND NON-AUDIT SERVICES

    Consistent with Securities and Exchange Commission requirements
regarding auditor independence, the Audit Committee has adopted a
policy to pre-approve all audit and permissible non-audit services
provided by the independent auditor. Under the policy, the Committee
must pre-approve services prior to commencement of the specified
service. The requests for pre-approval are submitted to the Audit
Committee by the Vice Chairman and Chief Financial Officer or his
designee with a statement as to whether in their view the request is
consistent with the Securities and Exchange Commission's rules on
auditor independence.

    As is customary, accountants for the current fiscal year will,
upon the recommendation of the Audit Committee, be appointed by the
Board of Directors at their meeting immediately following the Annual
Meeting of the Shareholders.

       management performance and involvement in activities or
       interests that do not create a conflict with a director's
