RECORD DATE The board of directors has fixed the close of business on March 21, 2003 as the record date for the Annual Meeting (the "Record Date"). Only stockholders of record at the Record Date (the "Stockholders") are entitled to notice of and to vote at the Annual Meeting or at any adjournments thereof, in person or by proxy. At the Record Date, there were 95,451,708 shares of our common stock outstanding. This proxy statement, the accompanying proxy card and our Annual Report to stockholders are intended to be mailed on or about April 1, 2003 to each Stockholder entitled to vote at the Annual Meeting. PROXIES The proxy accompanying this proxy statement is solicited on behalf of our board of directors for use at the Annual Meeting and any adjournments of the Annual Meeting, and the expenses of solicitation of proxies will be borne by us. The solicitation will be made primarily by mail, but our officers and regular employees may also solicit proxies by telephone, telegraph, facsimile, via the Internet or in person. We also have retained Georgeson Shareholder Services to assist in soliciting proxies. Each holder of common stock is entitled to one vote for each share of our common stock held. The holders in person or by proxy of a majority of the common stock entitled to be voted at the Annual Meeting shall constitute a quorum. Each Stockholder may appoint a person (who need not be a shareholder) other than the persons named in the enclosed proxy to represent him or her at the meeting by completing another proper proxy. In either case, such completed proxy should be returned in the enclosed envelope provided for that purpose for delivery before the meeting or should be delivered to our Secretary at 600 Third Avenue, New York, New York 10016, not later than 5 p.m., eastern daylight time, on Monday, April 21, 2003. Any proxy delivered pursuant to this solicitation is revocable at the option of the person(s) executing the proxy upon our receipt, prior to the time the proxy is voted, of a duly executed instrument revoking it, or of a duly executed proxy bearing a later date, or in the case of death or incapacity of the person(s) executing the proxy, of written notice of such death or incapacity, or by such person(s) voting in person at the Annual Meeting. Unless revoked, all proxies representing shares entitled to vote which are delivered pursuant to this solicitation will be voted at the Annual Meeting and, where a choice has been specified on the proxy card, will be voted in accordance with such specification. WHERE A CHOICE HAS NOT BEEN SPECIFIED ON THE PROXY CARD, THE PROXY WILL BE VOTED IN ACCORDANCE WITH THE RECOMMENDATIONS OF YOUR BOARD OF DIRECTORS. Assuming a quorum is present, a majority of the shares of common stock present in person or represented by proxy at the Annual Meeting is required for the election of directors and for approval of all other items submitted to Stockholders for their consideration. Abstentions and instances where brokers are prohibited from exercising discretionary authority for beneficial owners who have not returned a proxy (so-called "broker non-votes") will be counted for purposes of determining a quorum, but will not be counted as either voting for or against any proposal. 1

VOTING BY TELEPHONE OR INTERNET Instead of submitting your vote by mail on the enclosed proxy card, you can vote by telephone or over the Internet. The telephone and Internet voting procedures, which comply with Delaware law, are designed to authenticate Stockholders' identities, to allow Stockholders to vote their shares and to confirm that their instructions have been properly recorded. Voting your proxy by mail, telephone or the Internet will not limit your right to vote at the Annual Meeting if you later decide to attend in person. If your shares are held in the name of a broker, bank or other record holder, you must obtain a proxy from the record holder as to how to vote your shares or obtain a proxy from the record holder to vote at the Annual Meeting. Stockholders with shares registered directly in their name in our stock records maintained by our transfer agent, EquiServe Trust Company, N.A., may vote their shares (1) by making a toll-free telephone call from the U.S. and Canada to EquiServe at 1-877-PRX-VOTE (1-877-779-8683), (2) by submitting their proxy over the Internet at the following address on the World Wide Web: http://www.eproxyvote.com/lll, or (3) by mailing their signed proxy card. Specific instructions to be followed by registered Stockholders are set forth on the enclosed proxy card. Proxies submitted by telephone or over the Internet as described above must be received by 5:00 p.m., eastern daylight time, on April 21, 2003. REVOCATION OF PROXIES SUBMITTED BY TELEPHONE OR INTERNET To revoke a proxy previously submitted by telephone or over the Internet, you may simply vote again at a later date, using the same procedures, in which case your later submitted vote will be recorded and your earlier vote revoked, or by attending the meeting and voting in person.

THE BOARD OF DIRECTORS AND CERTAIN COMMITTEES OF THE BOARD Our board of directors directs the management of our business and affairs, as provided by Delaware law, and conducts its business through meetings of the board of directors and two standing committees: the audit and compensation committees. In addition, from time to time, special committees may be established under the direction of the board of directors when necessary to address specific issues. We have no nominating committee; however, the audit committee has agreed to perform the functions of the nominating committee. Each executive officer serves at the discretion of the board of directors. During the fiscal year ended December 31, 2002, the board of directors held four regularly scheduled meetings and one special meeting. All of our directors attended at least 75% of the combined number of board of directors meetings and committee meetings during the past fiscal year. The audit committee currently consists of Messrs. Corcoran, Shalikashvili (Chairman) and Simon. This committee, which met nine times during 2002, including four meetings by telephone, is responsible generally for recommending to the board of directors the independent accountants to be nominated to audit our financial statements; approving the compensation of the independent accountants; meeting with our independent accountants to review the proposed scope of the annual audit of our financial statements; reviewing the findings of the independent accountants with respect to the annual audit; and reviewing with management and the independent accountants our periodic financial reports prior to our filing them with the SEC and reporting annually to the board of directors with respect thereto. The compensation committee consists of Messrs. Millard (Chairman), Montague and Washkowitz. This committee, which acted by written consent four times during 2002, is responsible for administering our 1997 Stock Option Plan for Key Employees (the "1997 Plan") and our 1999 Long Term Performance Plan (the "1999 Plan") and has limited authority to adopt amendments to those plans. This committee is also responsible for recommending to the board of directors the salaries to be paid to our Chief Executive Officer and the President, and reviewing and approving the Chief Executive Officer's and the President's other annual cash compensation and long-term incentives and the total compensation to be paid to certain of our other executive officers. COMPENSATION OF DIRECTORS The directors who are also our employees or employees of our subsidiaries or affiliates do not receive compensation for their services as directors. The non-affiliated directors receive annual compensation of $30,000 for service on the board of directors, of which $25,000 is paid in cash on a quarterly basis, and $5,000 is paid in shares of our common stock. The chairman of both the audit committee and the compensation committee each receives additional cash annual compensation of $3,500. In addition, non-affiliated directors receive annual stock option grants of shares of our common stock, which vest in three equal annual installments. The non-affiliated directors are entitled to reimbursement for their reasonable out-of-pocket expenses in connection with their travel to and attendance at meetings of the board of directors or committees thereof. In addition, the non-affiliated directors will be compensated $1,250 per meeting attended, including committee meetings, up to a maximum of $2,500 per day. Non-affiliated directors may defer up to 100 percent of the cash portion of their annual cash compensation (including meeting fees) otherwise payable to the director. Subject to certain limitations, a participating director's deferred compensation will be distributed in a lump sum on, or distributed in annual installments commencing on, the 30th day following the date he or she ceases to be a director. Deferral elections are irrevocable during any calendar year and must be made before the beginning of the calendar year in which his/her compensation is earned. Interest is accrued on deferred amounts. Depending on a director's investment election, deferred amounts earn interest at a rate based on the 90-day U.S. Government Treasury Bill or the performance of our common stock. 6

Of the number of shares shown above, (i) the following represent shares that may be acquired upon exercise of employee stock options for the accounts of: Mr. Lanza, 1,661,906 shares; Mr. LaPenta, 1,661,906 shares; Mr. Strianese, 75,000 shares, Mr. Cambria, 89,800 shares and Mr. Schafer, 27,000 shares; and (ii) the following represent shares allocated under our saving plans to the accounts of: Mr. LaPenta, 887 shares; Mr. Strianese, 835 shares; Mr. Cambria, 831 shares; and Mr. Schafer, 800 shares. (2) The number of shares shown includes shares that are individually or jointly owned, as well as shares over which the individual has either sole or shared investment or voting authority. (3) Share ownership does not exceed one percent of the class unless otherwise indicated. Under Rule 13d-3, certain shares may be deemed to be beneficially owned by more than one person (if, for example, persons share the power to vote or the power to dispose of the shares). In addition, shares are deemed to be beneficially owned by a person if the person has the right to acquire the shares (for example, upon exercise of an option) within 60 days of the date as of which the information is provided. In computing the percentage ownership of any person, the amount of shares outstanding is deemed to include the amount of shares beneficially owned by such person (and only such person) by reason of these acquisition rights. As a result, the percentage of outstanding shares of any person as shown in this table does not necessarily reflect the person's actual ownership or voting power with respect to the number of shares of common stock actually outstanding at March 21, 2003. (4) Includes 9,334 shares issuable and exercisable under director stock options within 60 days of March 21, 2003 in the case of Messrs. Corcoran, Montague, and Shalikashvili, 6,334 shares in the case of Mr. Simon and 3,334 shares in the case of Messrs. Millard and Washkowitz. (5) Robert B. Millard and Alan H. Washkowitz, each of whom is a member of our board of directors, are each a Managing Director of Lehman Brothers Inc. and limited partners of Lehman Brothers Capital Partners III, L.P. As limited partners of Lehman Brothers Capital Partners III, L.P., Messrs. Millard and Washkowitz may be deemed to share beneficial ownership of shares of our common stock held by Lehman Brothers Capital Partners III, L.P. Such individuals disclaim any such beneficial ownership and those shares of common stock are not reflected in the numbers shown in this table. (6) Includes 105,278 shares owned by a charitable foundation of which Mr. Millard and his wife are the sole trustees, and as to which Mr. Millard disclaims beneficial ownership. (7) Includes 111,330 shares in trust, for the benefit of Mr. Washkowitz's children, for which Mr. Washkowitz and his wife are co-trustees and as to which Mr. Washkowitz disclaims beneficial ownership.

REPORT OF THE AUDIT COMMITTEE The directors who serve on the audit committee are all "independent" in accordance with the New York Stock Exchange listing standards. We have reviewed and discussed with management the Company's audited financial statements as of and for the year ended December 31, 2002. As part of our governance practices, the Audit Committee periodically reviews its charter and recommends to the board of directors changes to its charter. The board of directors adopted changes to the audit committee charter in March, 2003, in part to comply with the Sarbanes-Oxley Act of 2002. The revised audit committee charter is included in this proxy statement as Exhibit A. We have discussed with the independent auditors, PricewaterhouseCoopers LLP, the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended, by the Auditing Standards Board of the American Institute of Certified Public Accountants. We have received and reviewed the written disclosures and the letter from PricewaterhouseCoopers LLP, required by Independence Standard No. 1, Independence Discussions with Audit Committees, as amended, by the Independence Standards Board, and have discussed with the auditors their independence. Based on the activities referred to above, we recommended to the board of directors that the financial statements referred to above be included in our Annual Report on Form 10-K for the year ended December 31, 2002. Members of the audit committee are Thomas A. Corcoran, John M. Shalikashvili (Chairman) and Arthur L. Simon. INDEPENDENT AUDITOR FEES For services rendered in 2002 by PricewaterhouseCoopers LLP, our independent auditors, we incurred the following fees: o AUDIT FEES (for the audit of the 2002 financial statements and quarterly reviews).................................................. $2,038,300 o FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES ........................................ $0 o ALL OTHER FEES ($1,851,000 for tax services, $1,062,000 for a business process review and $1,414,126 for other audit services, which include acquisition audits, review of SEC registrations, benefit plan audits, other statutory audits and $128,000 applicable to the audit of our 2001 financial statements)............................. $4,327,126 The audit committee has considered and determined that the provision of the services covered under the caption All Other Fees is compatible with maintaining the auditor's independence. COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The compensation committee is responsible for reviewing the design of, and pay levels generated by, our compensation and benefit programs for our executive officers. The committee is also responsible for administering our stock option program. The committee is committed to ensuring an executive compensation program that supports our mission -- to maximize stockholder value. Thus, the executive compensation is structured around the following tenets: o Total compensation programs should strengthen the relationship between pay and performance by emphasizing variable, at-risk compensation that is dependent on our achievements and individual performance goals. o Management should be focused on the long-term interests of stockholders. Thus, a significant portion of the compensation opportunity should be long-term, at-risk pay in the form of stock options. 13

o We must maintain our ability to attract, retain, and encourage the development of qualified, capable executives. Total compensation opportunities will mirror those offered by comparably sized organizations within the aerospace and defense industries -- for those positions where the labor market is not limited to these industries, we will reference broader general industry information for similarly sized organizations. The comparative group used for compensation purposes will generally be broader than the group that comprises the published industry index in the performance graph included in this proxy statement. The compensation committee believes that our competition for executive talent is not limited to the companies included in the published industry index established for comparing stockholder returns. The key elements of our executive compensation program are base salary, annual incentives, and long-term compensation. These key elements are addressed separately below. BASE SALARIES The compensation committee will regularly review the base salary for the Chief Executive Officer and the President. We have established internal relationships of other senior executive positions to those of the Chief Executive Officer and the President, and base salaries for these other positions flow from those relationships. Base salaries will be targeted at the median of market levels with adjustments above or below market to recognize varying levels of responsibility, prior experience, breadth of knowledge, as well as external pay practices. Increases to base salaries will be driven primarily by individual performance. Individual performance will be evaluated based on sustained levels of individual contribution. As reflected in the Summary Compensation Table, Mr. Lanza's base salary was $825,000 in 2002 and $750,000 in 2001 and 2000 as provided for in his employment agreement. In determining future increases to Mr. Lanza's base salary, the compensation committee will consider his individual performance as measured by short-term achievements as well as his contributions to long-term organizational success. The compensation committee will also compare Mr. Lanza's base salary to base salaries of chief executive officers among comparable companies. ANNUAL INCENTIVES The annual incentive plan is structured to provide a variable pay opportunity based on performance. Actual bonuses are based on an assessment of the participant's contributions toward organizational success. Mr. Lanza received a bonus of $850,000 in 2002 and $750,000 in 2001. Mr. LaPenta received a bonus of $750,000 in 2002 and $650,000 in 2001. LONG-TERM INCENTIVES Long-term incentives are provided pursuant to the 1997 Plan and the 1999 Plan. Stock options will be granted at a price not less than the fair market value of our common stock on the date of grant. The ultimate value of an option grant to the recipient depends on the stockholder value created between the date of grant and the date of exercise. Option award size is based primarily on competitive practice but may also be adjusted to reflect factors such as individual and our company's performance. Mr. Lanza and Mr. LaPenta were each granted options to purchase 400,000 shares of our common stock in 2002. POLICY WITH RESPECT TO THE $1 MILLION DEDUCTION LIMIT Section 162(m) of the Internal Revenue Code generally limits the corporate deduction for compensation paid to the named executive officers to $1 million, unless certain requirements are met. 14

The compensation committee will consider the impact of this provision when making compensation decisions. However, the compensation committee will weigh all pertinent factors to determine appropriate plan design and incentive awards. Members of the compensation committee are Robert B. Millard (Chairman), John E. Montague and Alan H. Washkowitz. 15

STOCK PERFORMANCE GRAPH The graph below compares the cumulative total return of our common stock, as adjusted for our 2 for 1 stock split on May 20, 2002, with the cumulative total return of the Standard & Poor's 500 Composite Stock Index, the Standard & Poor's 1500 Aerospace & Defense Index and a peer group index, for the period from May 19, 1998 to December 31, 2002. We are one of the companies included in the Standard & Poor's 1500 Aerospace & Defense Index. The peer group index is composed of Alliant Techsystems Inc., General Dynamics Corporation and Northrop Grumman Corporation. These figures assume that all dividends paid over the performance period were reinvested, and that the starting value of each index and the investment in our common stock was $100 on May 19, 1998. The starting point for the measurement of our common stock cumulative total return was our initial public offering price of $11.00 per share, as adjusted for our stock split. The graph is not, and is not intended to be, indicative of future performance of our common stock. In the future, we will replace our peer group index with the Standard & Poor's 1500 Aerospace & Defense Index because this published industry index comprises a more comprehensive list of companies that operate in the defense industry than the peer group index we have historically presented. In accordance with Item 402 of Regulation S-K, we present for comparison with our total return the returns of both the newly selected index and the peer group index used in our proxy statement of last year.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION During the 2002 fiscal year, Messrs. Robert Millard, John Montague and Alan Washkowitz served as members of the compensation committee of the board of directors. None of these individuals has served us or any of our subsidiaries as an officer or employee. None of our executive officers serves as a member of the board of directors or compensation committee of any entity which has one or more executive officers serving as a member of our board of directors or compensation committee. EMPLOYMENT AGREEMENTS We entered into an employment agreement (the "Employment Agreements") effective on April 30, 1997 with each of Mr. Lanza, our Chairman and Chief Executive Officer, and Mr. LaPenta, our President and Chief Financial Officer. The Employment Agreements provided for an initial term of five years, which would automatically renew for one-year periods thereafter, unless a party thereto gave notice of its intent to terminate at least 90 days prior to the expiration of the term. Mr. Lanza's employment agreement was renewed in April, 2002. Mr. LaPenta's employment agreement expired in April, 2002. Upon a termination without cause or resignation for good reason, we will be obligated, through the end of the term, to (i) continue to pay the base salary and (ii) continue to provide life insurance and medical and hospitalization benefits comparable to those provided to other senior executives; provided, however, that any such coverage shall terminate to the extent that Mr. Lanza is offered or obtains comparable benefits coverage from any other employer. The Employment Agreements provided for confidentiality during employment and at all times thereafter. There was also a noncompetition and non-solicitation covenant which was effective during the employment term and for one year thereafter; provided, however, that if the employment terminated following the expiration of the initial term, the noncompetition covenant would only be effective during the period, if any, that we paid the severance described above. 17

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS STOCKHOLDERS AGREEMENT In connection with our incorporation we, Lehman Brothers Capital Partners III, L.P. and certain of its affiliates, Messrs. Lanza and LaPenta and Lockheed Martin Corporation entered into the Stockholders Agreement, which has terminated except for the terms relating to registration rights. Pursuant to the Stockholders Agreement, at this time Messrs. Lanza and LaPenta and the Lehman Partnership have the right, subject to certain conditions, to require L-3 Communications Holdings to register their shares of our common stock under the Securities Act of 1933. The Lehman Partnership has four demand rights and each of Messrs. Lanza and LaPenta has one demand registration right. Lockheed Martin Corporation sold all of its shares of our common stock in 1999. As of March 21, 2003, the Lehman Partnership owned 2.3% of our common stock. In addition, the Stockholders Agreement also provides Messrs. Lanza and LaPenta and the Lehman Partnership with piggyback registration rights. The Stockholders Agreement provides, among other things, that we will pay expenses incurred in connection with: o up to three demand registrations requested by the Lehman Partnership and the two demand registrations requested by each of Messrs. Lanza and LaPenta; and o any registration in which those parties participate through piggyback registration rights granted under the agreement. SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934 requires our officers and directors, and persons who own more than 10% of a registered class of our equity securities, to file reports of ownership and changes in ownership with the SEC and the NYSE. Officers, directors and greater than 10% shareholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file. All Section 16(a) forms required to be filed were filed on a timely basis, except that Mr. Robert LaPenta failed to file one Form 4 on a timely basis that reported entering into a hedging arrangement termed a "variable prepaid forward agreement." 19
