DELIVERY OF THIS INSTRUMENT TO AN ADDRESS OTHER THAN AS SET FORTH ABOVE, OR TRANSMISSION OF THIS LETTER OF TRANSMITTAL VIA FACSIMILE OTHER THAN AS SET FORTH ABOVE, WILL NOT CONSTITUTE A VALID DELIVERY OF THIS LETTER OF TRANSMITTAL.

The undersigned acknowledges that he or she has received and reviewed the prospectus, dated , 2005 (the "Prospectus"), of DRS Technologies, Inc., a Delaware corporation ("DRS"), and this Letter of Transmittal (the "Letter"), which together constitute DRS's offer (the "Exchange Offer"), to exchange an aggregate principal amount of up to $200.00 million of its 6-⁷/8% Senior Subordinated Notes due 2013 and the related Subsidiary Guarantees which have been registered under the Securities Act of 1933, as amended, (individually a "Note" and collectively, the "Notes"), for a like principal amount at maturity of DRS's issued and outstanding 6-⁷/8% Senior Subordinated Notes due 2013 and the related Subsidiary Guarantees (individually an "Old Note" and collectively, the "Old Notes") from the registered holders thereof. Capitalized terms not defined herein shall have the respective meanings ascribed to them in the Prospectus.

For each Old Note accepted for exchange, the holder of such Old Note will receive a New Note having a principal amount equal to the principal amount at maturity of the surrendered Old Note. The New Notes will bear interest from the most recent date to which interest has been paid on the Old Notes, or if no interest has

been paid, from November 1, 2004. Accordingly, registered holders of New Notes on the relevant record date for the first interest payment date following the consummation of the Exchange Offer will receive interest accruing from the most recent date to which interest has been paid on the Old Notes. The Old Notes accepted for exchange will cease to accrue interest from and after the date of consummation of the Exchange Offer. Holders of Old Notes whose Old Notes are accepted for exchange will not receive any payment in respect of accrued interest on such Old Notes otherwise payable on any interest payment date the record date for which occurs on or after the consummation of the Exchange Offer.

This Letter is to be completed by a holder of Old Notes either if certificates for such Old Notes are to be forwarded herewith or if a tender is to be made by book-entry transfer to the account maintained by the Exchange Agent at The Depository Trust Company ("DTC") pursuant to the procedures set forth in "The Exchange Offer-Book-Entry Transfers" section of the Prospectus and an Agent's Message is not delivered. HOLDERS OF OLD NOTES WHO HAVE PREVIOUSLY VALIDLY DELIVERED A LETTER OF TRANSMITTAL IN CONJUNCTION WITH A VALID TENDER OF OLD NOTES FOR EXCHANGE PURSUANT TO THE PROCEDURES DESCRIBED IN THE PROSPECTUS UNDER THE HEADING "THE EXCHANGE OFFER" ARE NOT REQUIRED TO TAKE ANY FURTHER ACTION TO RECEIVE NEW NOTES. HOLDERS OF OLD NOTES WHO HAVE PREVIOUSLY VALIDLY TENDERED OLD NOTES FOR EXCHANGE OR WHO VALIDLY TENDER OLD NOTES FOR EXCHANGE IN ACCORDANCE WITH THIS LETTER MAY WITHDRAW ANY OLD NOTES SO TENDERED AT ANY TIME PRIOR TO THE EXPIRATION DATE. SEE THE PROSPECTUS UNDER THE HEADING "THE EXCHANGE OFFER" FOR A MORE COMPLETE DESCRIPTION OF THE TENDER AND WITHDRAWAL PROVISIONS. Tenders by book-entry transfer also may be made by delivering an Agent's Message in lieu of this Letter. The term "Agent's Message" means a message, transmitted by DTC to and received by the Exchange Agent and forming a part of a Book-Entry Confirmation (as defined below), which states that DTC has received an express acknowledgment from the tendering participant, which acknowledgment states that such participant has received and agrees to be bound by this Letter and that DRS may enforce this Letter against such participant. Holders of Old Notes whose certificates are not immediately available, or who are unable to deliver their certificates or confirmation of the book-entry tender of their Old Notes into the Exchange Agent's account at DTC (a "Book-Entry Confirmation") and all other documents required by this Letter to the Exchange Agent on or prior to the Expiration Date, must tender their Old Notes according to the guaranteed delivery procedures set forth in "The Exchange Offer-Guaranteed delivery procedures" section of the Prospectus. See Instruction 1.

Delivery of documents to DTC does not constitute delivery to the Exchange Agent.

The method of delivery of Old Notes, Letters of Transmittal and all other required documents are at the election and risk of the holders. If such delivery is by mail it is recommended that registered mail properly insured, with return receipt requested, be used. In all cases, sufficient time should be allowed to assure timely delivery. No letters of transmittal or Old Notes should be sent to DRS.

The undersigned has completed the appropriate boxes below and signed this Letter to indicate the action the undersigned desires to take with respect to the Exchange Offer.

If the undersigned is not a broker-dealer, the undersigned represents that it is not engaged in, and does not intend to engage in, a distribution of New Notes. If the undersigned is a broker-dealer that will receive New Notes for its own account in exchange for Old Notes that were acquired as a result of market-making activities or other trading activities, it acknowledges that it will deliver a prospectus in connection with any resale of such New Notes; however, by so acknowledging and by delivering such a prospectus, the undersigned will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

Upon the terms and subject to the conditions of the Exchange Offer, the undersigned hereby tenders to DRS the aggregate principal amount at maturity of Old Notes indicated above. Subject to, and effective upon, the acceptance for exchange of the Old Notes tendered hereby, the undersigned hereby sells, assigns and transfers to, or upon the order of, DRS all right, title and interest in and to such Old Notes as are being tendered hereby.

The undersigned hereby irrevocably constitutes and appoints the Exchange Agent as the undersigned's true and lawful agent and attorney-in-fact with respect to such tendered Old Notes, with full power of substitution, among other things, to cause the Old Notes to be assigned, transferred and exchanged. The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the Old Notes, and to acquire New Notes issuable upon the exchange of such tendered Old Notes, and that, when the same are accepted for exchange, DRS will acquire good and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim when the same are accepted by DRS. The undersigned hereby further represents that any New Notes acquired in exchange for Old Notes tendered hereby will have been acquired in the ordinary course of business of the person receiving such New Notes, whether or not such person is the undersigned, that neither the Holder of such Old Notes nor any such other person is participating in, intends to participate in or has an arrangement or understanding with any person to participate in the distribution of such New Notes and that neither the Holder of such Old Notes nor any such other person is an "affiliate," as defined in Rule 405 under the Securities Act, of DRS.

The undersigned acknowledges that this Exchange Offer is being made in reliance on interpretations by the staff of the Securities and Exchange Commission (the "SEC"), as set forth in no-action letters issued to third parties, that the New Notes issued pursuant to the Exchange Offer in exchange for the Old Notes may be offered for resale, resold and otherwise transferred by Holders thereof (other than any such Holder that is an "affiliate" of DRS within the meaning of Rule 405 under the Securities Act), without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such New Notes are acquired in the ordinary course of such Holders' business, such Holders are not holding any Old Notes that have the status of, or are reasonably likely to have the status of, an unsold allotment in the initial offering, and such Holders have no arrangement with any person to participate in the distribution of such New Notes. However, the SEC has not considered the Exchange Offer in the context of a no-action letter, and there can be no assurance that the staff of the SEC would make a similar determination with respect to the Exchange Offer as in other circumstances. If the undersigned is not a broker-dealer, the undersigned represents that it is not engaged in and does not intend to engage in, a distribution of New Notes and has no arrangement or understanding to participate in a distribution of New Notes. If any Holder is an affiliate of DRS, is engaged in or intends to engage in or has any arrangement or understanding with respect to the distribution of the New Notes to be acquired pursuant to the Exchange Offer, such Holder (i) could not rely on the applicable interpretations of the staff of the SEC and (ii) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction. If the undersigned is a broker-dealer that will receive New Notes for its own account in exchange for Old Notes, it represents that the Old Notes to be exchanged for the New Notes were acquired by it as a result of market-making activities or other trading activities and acknowledges that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Notes; however, by so acknowledging and by delivering a prospectus meeting the requirements of the Securities Act, the undersigned will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

The undersigned will, upon request, execute and deliver any additional documents deemed by DRS to be necessary or desirable to complete the sale, assignment and transfer of the Old Notes tendered hereby. All authority conferred or agreed to be conferred in this Letter and every obligation of the undersigned hereunder shall be binding upon the successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of the undersigned and shall not be affected by, and shall survive, the death or incapacity of the undersigned. This tender may be withdrawn only in accordance with the procedures set forth in "The Exchange Offer-Withdrawal Rights" section of the Prospectus.

Unless otherwise indicated herein in the box entitled "Special Issuance Instructions" below, please deliver the New Notes (and, if applicable, substitute certificates representing Old Notes for any Old Notes not exchanged) in the name of the undersigned or, in the case of a book-entry delivery of Old Notes, please credit the account indicated above maintained at DTC. Similarly, unless otherwise indicated under the box entitled "Special Delivery Instructions" below, please send the New Notes (and, if applicable, substitute certificates representing Old Notes for any Old Notes not exchanged) to the undersigned at the address shown above in the box entitled "Description of Old Notes."

1. DELIVERY OF THIS LETTER AND NOTES; GUARANTEED DELIVERY PROCEDURES.

This Letter is to be completed by holders of Old Notes either if certificates are to be forwarded herewith or if tenders are to be made pursuant to the procedures for delivery by book-entry transfer set forth in "The Exchange Offer-Book-Entry Transfers" section of the Prospectus and an Agent's Message is not delivered. Tenders by book-entry transfer also may be made by delivering an Agent's Message in lieu of this Letter. The term "Agent's Message" means a message, transmitted by DTC to and received by the Exchange Agent and forming a part of a Book-Entry Confirmation, which states that DTC has received an express acknowledgment from the tendering participant, which acknowledgment states that such participant has received and agrees to be bound by, and makes the representations and warranties contained in, the Letter and that DRS may enforce the Letter against such participant. Certificates for all physically tendered Old Notes, or Book-Entry Confirmation, as the case may be, as well as a properly completed and duly executed Letter (or manually signed facsimile hereof or Agent's Message in lieu thereof) and any other documents required by this Letter, must be received by the Exchange Agent at the address set forth herein prior to the Expiration Date, or the tendering holder must comply with the guaranteed delivery procedures set forth below. Old Notes tendered hereby must be in denominations of principal amount at maturity of $1,000 and any integral multiple thereof.

Holders whose certificates for Old Notes are not immediately available or who cannot deliver their certificates and all other required documents to the Exchange Agent before the Expiration Date, or who cannot complete the procedure for book-entry transfer on a timely basis, may tender their Old Notes pursuant to the guaranteed delivery procedures set forth in "The Exchange Offer Guaranteed Delivery Procedures" section of the Prospectus. Pursuant to such procedures, (i) such tender must be made through an Eligible Institution, (ii) prior to 5:00 p.m., New York City time, on the Expiration Date, the Exchange Agent must receive from such Eligible Institution a properly completed and duly executed Letter (or a facsimile thereof) and Notice of Guaranteed Delivery, substantially in the form provided by DRS (by facsimile transmission, mail or hand delivery), setting forth the name and address of the holder of Old Notes and the amount of Old Notes tendered, stating that the tender is being made thereby and guaranteeing that within three New York Stock Exchange ("NYSE") trading days after the date of execution of the Notice of Guaranteed Delivery, the certificates for all physically tendered Old Notes, in proper form for transfer, or a Book-Entry Confirmation, as the case may be, together with a properly completed and duly executed Letter (or facsimile thereof or Agent's Message in lieu thereof) with any required signature guarantees and any other documents required by this Letter will be deposited by the Eligible Institution with the Exchange Agent, and (iii) the certificates for all physically tendered Old Notes, in proper form for transfer, or a Book-Entry Confirmation, as the case may be, together with a properly completed and duly executed Letter (or facsimile thereof or Agent's Message in lieu thereof) with any required signature guarantees and all other documents required by this Letter, are received by the Exchange Agent within three NYSE trading days after the Expiration Date.

The method of delivery of this Letter, the Old Notes and all other required documents is at the election and risk of the tendering holders, but the delivery will be deemed made only when actually received or confirmed by the Exchange Agent. If Old Notes are sent by mall, it is suggested that the mailing be registered mail, properly insured, with return receipt requested, made sufficiently in advance of the Expiration Date to permit delivery to the Exchange Agent prior to 5:00 p.m, New York City time, on the Expiration Date.

See "The Exchange Offer" section of the Prospectus.

2. PARTIAL TENDERS (NOT APPLICABLE TO NOTE HOLDERS WHO TENDER BY BOOK-ENTRY TRANSFER).

If less than all of the Old Notes evidenced by a submitted certificate are to be tendered, the tendering holder(s) should fill in the aggregate principal amount at maturity of Old Notes to be tendered in the box above entitled "Description of Old Notes-Principal Amount at Maturity Tendered." A reissued certificate representing the balance of non tendered Old Notes will be sent to such tendering holder, unless otherwise provided in the appropriate box on this Letter, promptly after the Expiration Date. All of the Old Notes delivered to the Exchange Agent will be deemed to have been tendered unless otherwise indicated.

3. SIGNATURES ON THIS LETTER; BOND POWERS AND ENDORSEMENTS; GUARANTEE OF SIGNATURES.

If this Letter is signed by the Holder of the Old Notes tendered hereby, the signature must correspond exactly with the name as written on the face of the certificates or on DTC's security position listing as the holder of such Old Notes without any change whatsoever.

If any tendered Old Notes are owned of record by two or more joint owners, all of such owners must sign this Letter.

If any tendered Old Notes are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate copies of this Letter as there are different registrations of certificates.

When this Letter is signed by the registered holder or holders of the Old Notes specified herein and tendered hereby, no endorsements of certificates or separate bond powers are required. If, however, the New Notes are to be issued, or any untendered Old Notes are to be reissued, to a person other than the registered holder, then endorsements of any certificates transmitted hereby or separate bond powers are required. Signatures on such certificate(s) must be guaranteed by a participant in a securities transfer association recognized signature program.

If this Letter is signed by a person other than the registered holder or holders of any certificates) specified herein, such certificate(s) must be endorsed or accompanied by appropriate bond powers, in either case signed exactly as the name or names of the registered holder or holders appear(s) on the certificate(s) and signatures on such certificate(s) must be guaranteed by an Eligible Institution.

If this Letter or any certificates or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and, unless waived by DRS, proper evidence satisfactory to DRS of their authority to so act must be submitted.

Endorsements on certificates for old notes or signatures on bond powers required by this Instruction 3 must be guaranteed by a firm which is a financial institution (including most banks, savings and loan associations and brokerage houses) that is a participant in the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Program or the Stock Exchanges Medallion Program (each an "Eligible Institution").

Signatures on this letter need not be guaranteed by an Eligible Institution, provided the Old Notes are tendered: (i) by a registered holder of Old Notes (which term, for purposes of the exchange offer, includes any participant in DTC's system whose name appears on a security position listing as the holder of such Old Notes) who has not completed the box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on this letter, or (ii) for the account of an Eligible Institution.

4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.

Tendering holders of Old Notes should indicate in the applicable box the name and address to which New Notes issued pursuant to the Exchange Offer and/or substitute certificates evidencing Old Notes not exchanged are to be issued or sent, if different from the name or address of the person signing this Letter. In the case of issuance in a different name, the employer identification or social security number of the person named also must be indicated. Note holders tendering Old Notes by book-entry transfer may request that Old Notes not exchanged be credited to such account maintained at DTC as such note holder may designate hereon. If no such instructions are given, such Old Notes not exchanged will be returned to the name and address of the person signing this Letter.

5. TAXPAYER IDENTIFICATION NUMBER AND BACKUP WITHHOLDING.

Under Federal income tax law, any tendering holder must provide the Exchange Agent (as payor) with such holder's correct Taxpayer Identification Number (a "TIN") on "Substitute Form W-9" set forth herein, which, in the case of a holder who is an individual, is generally such holder's social security number. To prevent backup withholding, each tendering holder must provide such holder's correct TIN by completing the Substitute Form W-9 set forth herein, certifying under penalties of perjury that the TIN provided is correct (or that such holder is awaiting a TIN) and that (i) the holder is exempt from backup withholding, (ii) the holder has not been notified by the Internal Revenue Service that such holder is subject to backup withholding as a result of a failure to report all interest or dividends or (iii) the Internal Revenue Service has notified the holder that such holder is no longer subject to backup withholding. If the holder submitting this Letter of Transmittal is subject to backup withholding, the holder must cross out item (2) of Part III of the Substitute Form W-9. If such information is not provided on Substitute Form W-9, a penalty may be imposed by the Internal Revenue Service and payments may be subject to backup withholding (currently 28%), but such withholding will be refunded if the holder provides a correct TIN within 60 days.

If the holder does not have a TIN, such holder should consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 (the "W-9 Guidelines") for instructions on applying for a TIN, write "Applied For" in the space for the TIN in Part 1 of the Substitute Form W-9, and sign and date the Substitute Form W-9 and the Certificate of Awaiting Taxpayer Identification Number set forth herein. If the holder does not provide such holder's TIN to the Exchange Agent within 60 days, backup withholding will begin to apply and continue until such holder furnishes such holder's TIN to the Exchange Agent. Note: Writing "Applied For" on the form means that the holder has already applied for a TIN or that such holder intends to apply for one in the near future.

If the Old Notes are held in more than one name or are not in the name of the actual owner, consult the W-9 Guidelines for information on which TIN to report.

Certain holders (including, among others, all corporations and certain foreign individuals and entities) who are not subject to backup withholding should write "Exempt" in Part 2 of Substitute Form W-9, enter their correct TIN and sign and date the Substitute Form W-9 in the space provided. See the W-9 Guidelines for additional instructions. In order for a foreign person to qualify as exempt, such person must submit a completed Form W-8BEN, "Certificate of Foreign Status of Beneficial

Owner for United States Tax Withholding," signed under penalties of perjury attesting to such person's foreign status. Such form may be obtained from the Exchange Agent.

6. TRANSFER TAXES.

DRS will pay all transfer taxes, if any, applicable to the transfer of Old Notes to it or its order pursuant to the Exchange Offer. If, however, New Notes and/or substitute Old Notes not exchanged are to be delivered to, or are to be registered or issued in the name of, any person other than the registered holder of the Old Notes tendered hereby, or if tendered Old Notes are registered in the name of any person other than the person signing this Letter, or if a transfer tax is imposed for any reason other than the transfer of Old Notes to DRS or its order pursuant to the Exchange Offer, the amount of any such transfer taxes (whether imposed on the registered holder or any other persons) will be payable by the tendering holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted herewith, the amount of such transfer taxes will be billed directly to such tendering holder. Except as provided in this Instruction 6, it will not be necessary for transfer tax stamps to be affixed to the Old Notes specified in this Letter.

7. WAIVER OF CONDITIONS.

DRS reserves the right (in its reasonable discretion) to waive satisfaction of any or all conditions enumerated in the Prospectus.

8. NO CONDITIONAL TENDERS; DEFECTS.

No alternative, conditional, irregular or contingent tenders will be accepted. All tendering holders of Old Notes, by execution of this Letter or an Agent's Message in lieu thereof, shall waive any right to receive notice of the acceptance of their Old Notes for exchange.

Neither DRS, the Subsidiary Guarantors, the Exchange Agent nor any other person is obligated to give notice of any defect or irregularity with respect to any tender of Old Notes nor shall any of them incur any liability for failure to give any such notice.

9. MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES.

Any holder whose Old Notes have been mutilated, lost, stolen or destroyed should contact the Exchange Agent at the address indicated above for further instructions.

10. WITHDRAWAL RIGHTS.

Tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration Date.

For a withdrawal of a tender of Old Notes to be effective, a written notice of withdrawal must be received by the Exchange Agent at the address set forth above prior to 5:00 p.m., New York City time, on the Expiration Date. Any such notice of withdrawal must (i) specify the name of the person having tendered the Old Notes to be withdrawn (the "Depositor"), (ii) identify the Old Notes to be withdrawn (including certificate number or numbers and the principal amount at maturity of such Old Notes), (iii) contain a statement that such holder is withdrawing such holder's election to have such Old Notes exchanged, (iv) be signed by the holder in the same manner as the original signature on the Letter by which such Old Notes were tendered (including any required signature guarantees) or be accompanied by documents of transfer to have the Trustee with respect to the Old Notes register the transfer of such Old Notes in the name of the person withdrawing the tender and (v) specify the name in which such Old Notes are registered, if different from that of the Depositor. If Old Notes have been tendered pursuant to the procedure for book-entry transfer set forth in "The Exchange Offer-Book-Entry

Transfers" section of the Prospectus, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Old Notes and otherwise comply with the procedures of such facility. All questions as to the validity, form and eligibility (including time of receipt) of such notices will be determined by DRS (which power may be delegated to the Exchange Agent), whose determination shall be final and binding on all parties. Any Old Notes so withdrawn will be deemed not to have been validly tendered for exchange for purposes of the Exchange Offer and no New Notes will be issued with respect thereto unless the Old Notes so withdrawn are validly retendered. Any Old Notes that have been tendered for exchange but which are not exchanged for any reason will be returned to the holder thereof without cost to such holder (or, in the case of Old Notes tendered by book-entry transfer into the Exchange Agent's account at DTC pursuant to the book-entry transfer procedures set forth in "The Exchange Offer-Book-Entry Transfers" section of the Prospectus, such Old Notes will be credited to an account maintained with DTC for the Old Notes) as soon as practicable after withdrawal, rejection of tender or termination of the Exchange Offer. Properly withdrawn Old Notes may be retendered by following the procedures described above at any time prior to 5:00 p.m., New York City time, on the Expiration Date.

11. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.

Questions relating to the procedure for tendering, as well as requests for additional copies of the Prospectus and this Letter, and requests for Notices of Guaranteed Delivery and other related documents may be directed to the Exchange Agent at the address and telephone number indicated above.
