Item 1. Security and Issuer.

This statement on Schedule 13D relates to common stock, par value $0.01 per share (“Common Stock”), of Argon ST, Inc. (“Argon”). Argon has its principal offices at 12701 Fair Lakes Circle, Suite 800, Fairfax, Virginia 22033.

Item 2. Identity and Background.

(a)-(c) This statement is being jointly filed by each of the following persons pursuant to Rule 13d-1(k)(1) promulgated by the Securities and Exchange Commission (the “Commission”) pursuant to Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”):

(i) The Boeing Company, a Delaware corporation (“Boeing”), and

(ii) Vortex Merger Sub, Inc. (“Merger Sub”), a Delaware corporation and wholly owned subsidiary of Boeing.

Each of Boeing and Merger Sub are collectively referred to as the “Reporting Persons.” The Reporting Persons have entered into a Joint Filing Agreement, dated the date hereof, a copy of which is filed with this Schedule 13D as Exhibit 99.1 (which is hereby incorporated by reference) pursuant to which the Reporting Persons have agreed to file this statement jointly in accordance with the provisions of Rule 13d-1(k)(1) under the Exchange Act. The Reporting Persons expressly disclaim that they have agreed to act as a group other than as described in this statement.

Pursuant to Rule 13d-4 of the Exchange Act, the Reporting Persons expressly declare that the filing of this statement shall not be construed as an admission that any such person is, for the purposes of Section 13(d) and/or Section 13(g) of the Exchange Act or otherwise, the beneficial owner of any securities covered by this statement held by any other person.

The address of the principal business office of each of the Reporting Persons is 100 North Riverside Plaza, Chicago, Illinois 60606. Boeing is one of the world’s major aerospace firms. Merger Sub is a newly formed Delaware corporation and a wholly owned subsidiary of Boeing that was formed for the purpose of acquiring all of the outstanding shares of Argon. Merger Sub has not conducted, and does not expect to conduct, any business other than in connection with the potential acquisition of all the outstanding shares of Argon and the merger of Merger Sub with and into Argon.

Certain information required by this Item 2(a)-(c) concerning the directors and executive officers of each of the Reporting Persons is set forth on Schedule I annexed hereto, which is incorporated herein by reference.

(d)-(e) Within the past five years, none of the Reporting Persons and, to the knowledge of the Reporting Persons, none of the persons set forth on Schedule I, has been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors) or has been a party to any civil proceeding and as a result thereof was or is subject to any judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to federal or state securities laws or finding any violations with respect to such laws.

(f) Each of the Reporting Persons is organized under the laws of Delaware. Certain information required by this Item 2(f) concerning the directors and executive officers of each of the Reporting Persons is set forth on Schedule I annexed hereto, which is incorporated herein by reference.

Item 3. Source and Amount of Funds or Other Consideration.

On June 30, 2010, Boeing, Merger Sub, and Argon entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which Merger Sub has commenced a tender offer to purchase all of Argon’s outstanding shares of Common Stock (the “Offer”) at a price of $34.50 per share, net to the seller in cash, without interest thereon and subject to any required withholding taxes. Following the Offer, subject to the terms and conditions of the Merger Agreement, Merger Sub will be merged with and into Argon (the “Merger”), with Argon continuing as the surviving corporation and wholly owned by Boeing. In the Merger, each outstanding share of Common Stock will be converted into the right to receive $34.50, net to the seller in cash, without interest thereon and less any applicable withholding taxes.

As an inducement for Boeing and Merger Sub to enter into the Merger Agreement, on June 30, 2010, contemporaneously with the execution of the Merger Agreement, Terry L. Collins, Victor F. Sellier, and Thomas E. Murdock and certain of their affiliates (the “Significant Stockholders”), entered into tender and voting agreements with and in favor of Boeing and Merger Sub (the “Tender Agreements”) as described in Item 4 and Item 5 of this Schedule 13D. Boeing and Merger Sub entered into the Tender Agreements in connection with and as an inducement to the Merger Agreement, but did not make any cash or other payments with respect thereto. An aggregate of 7,584,090 shares of Common Stock are subject to the Tender Agreements. Pursuant to the Tender Agreements, if the Significant Stockholders acquire beneficial or record ownership of any additional shares of Common Stock, such shares will also be subject to the Tender Agreements.

The foregoing discussion does not purport to be complete, and is qualified in its entirety by the terms and conditions of the Merger Agreement and the Tender Agreements, copies of which are filed, respectively, as Exhibits 2.1 and 2.2 to Argon’s Current Report on Form 8-K, dated June 30, 2010, and Exhibits (e)(3) and (e)(4) to Argon’s Schedule 14D-9, dated July 8, 2010, and incorporated by reference into this Schedule 13D.

Item 4. Purpose of the Transaction.

(a)-(b) The Merger Agreement provides for the acquisition by Merger Sub of all of the outstanding shares of Common Stock through a tender offer and subsequent merger of Merger Sub with and into Argon, as a result of which Argon will become a wholly owned subsidiary of Boeing. The information contained in Item 3 is incorporated by reference herein.

Pursuant to the terms of the Tender Agreements, the Significant Stockholders have agreed to appoint Boeing and Merger Sub as proxy for such stockholders with the power to vote all shares covered by the Tender Agreements (the “Shares”) and beneficially owned at the time of the vote, whether at an annual, special, postponed, or adjourned meeting of Argon’s stockholders, or to grant consent or approval in any written consent in lieu of such a meeting: (i) in favor of approval of the Merger, (ii) in favor of any adjournment or postponement recommended by Argon of any stockholder meeting with respect to the Merger or the Merger Agreement, (iii) against any proposal to sell more than 15% of the equity or assets of Argon to anyone other than Boeing or Merger Sub or their affiliates, (iv) against any other merger, consolidation, business combination, reorganization, recapitalization, dissolution, or


CUSIP No.		040149106		Page		5		of		13

liquidation of Argon or its subsidiaries, and (v) against any other proposal or agreement that would (1) reasonably be expected to impede or otherwise interfere with the Merger, (2) result in a breach under the Merger Agreement, (3) result in any of the conditions in Article VII or Exhibit A of the Merger Agreement not being fulfilled or satisfied, or (4) change Argon’s dividend policy or capitalization, including the voting rights of any class of equity.

The purpose of entering into the Tender Agreements is to facilitate the acquisition of Common Stock in the Offer and, if necessary, the adoption of the Merger Agreement by the Argon stockholders. The Significant Stockholders’ obligations under the Tender Agreements will terminate upon the earliest to occur of: (i) the purchase of all of the Shares pursuant to the Offer in accordance with Section 3.01 of such Tender Agreement, (ii) the effective time of the Merger, (iii) the date the Merger Agreement is terminated in accordance with its terms, and (iv) the mutual consent of the Significant Stockholder and Boeing.

(d) Under the Merger Agreement, after Merger Sub accepts for payment Shares validly tendered in the Offer, Boeing is entitled to designate a number of directors, rounded up to the next whole number, to the board of directors of Argon and its subsidiaries that is equal to the total number of directors on Argon’s board of directors (giving effect to the directors elected or appointed pursuant to this sentence) multiplied by the percentage that the Shares beneficially owned by Boeing and its subsidiaries bears to the total number of Shares then outstanding. In this situation, at Boeing’s request, Argon shall promptly take all action requested by Boeing necessary or desirable to effect any such election or appointment, including filling vacancies or newly created directorships on Argon’s board of directors, increasing the size of Argon’s board of directors, and obtaining the resignations of such number of its current directors as is, in each case, necessary to enable such designees to be so elected or appointed to Argon’s board of directors in compliance with applicable law. After Merger Sub accepts for payment any Shares validly tendered in the Offer, Argon also agreed to cause Boeing’s designees to serve, in the same percentage (rounded up to the next whole number) as they hold on the board of directors, on each committee of Argon’s and its subsidiaries’ boards of directors (other than any committee of Argon’s board of directors established to take action with respect to the subject matter of the Merger Agreement), to the extent permitted by applicable law and the NASDAQ Marketplace Rules.

(e) Unless Boeing has given its prior written consent, the Merger Agreement prohibits Argon from (i) issuing, delivering, selling, pledging or otherwise encumbering any shares or other equity, voting interests, convertible securities or rights to acquire such equity, or stock appreciation rights or other rights linked to the value of Argon or Argon shares, except under limited circumstances set forth therein, (ii) declaring, setting aside or paying dividends or other distributions, other than dividends paid by wholly owned subsidiaries, (iii) splitting, combining or reclassifying any of its capital stock or other equity or voting interests or issuing or authorizing the issuance of any other securities in respect of, in lieu of or in substitution for shares of its capital stock or other equity or voting interests, and (iv) purchasing, redeeming or otherwise acquiring any Shares or any other securities of Argon or its subsidiaries or any options, warrants, calls or rights to acquire any such shares or other securities, except under limited circumstances set forth therein.

(f) Upon consummation of the Merger, Argon will become a wholly owned subsidiary of Boeing. After completion of the Offer and the Merger, Boeing expects to work with Argon’s management to evaluate and review Argon and its business, assets, corporate structure, operations, properties and strategic alternatives, and to integrate Argon into Boeing’s business units and market units. As a result of


CUSIP No.		040149106		Page		6		of		13

this review and integration, it is possible that Boeing could implement changes to Argon’s business or capitalization that could involve consolidating and streamlining certain operations and reorganizing or disposing of other businesses and operations, including the winding up of Argon’s separate existence and integration of Argon’s business and operations into Boeing. In addition, in connection with integrating Argon’s and Boeing’s corporate structure, Boeing may determine to reorganize, merge or consolidate Argon with one or more domestic or foreign subsidiaries of Boeing. Boeing reserves the right to change its plans and intentions at any time, as deemed appropriate.

(g) The Merger Agreement contains provisions that limit the ability of Argon to engage in a transaction that would entail a change of control of Argon during the pendency of the Merger Agreement. Following consummation of the Tender Offer, Merger Sub will own no less than a majority of Argon’s issued and outstanding capital stock and will therefore be able to block any acquisition of control of Argon by any other person.

(h) Upon consummation of the Merger, Argon’s Common Stock will cease to be quoted on any quotation system or exchange.

(i) Upon consummation of the Merger, Argon’s Common Stock will become eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act.

(j) Other than as described above, Boeing currently has no plan or proposal which relates to, or may result in, any of the matters listed in Items 4(a)-(i) of this Schedule 13D (although Boeing reserves the right to develop such plans).

Except as set forth in this Schedule 13D, neither Boeing, nor to the knowledge of Boeing, any of the directors or executive officers of Boeing listed on Schedule I hereto, has any present plans or intentions which would result in or relate to any of the actions described in subparagraphs (a) through (j) of Item 4 of this Schedule 13D.

The description contained in this Item 4 of the transactions contemplated by the Merger Agreement and the Tender Agreements does not purport to be complete, and is qualified in its entirety by the terms and conditions of the Merger Agreement and the Tender Agreements, copies of which are filed, respectively, as Exhibits 2.1 and 2.2 to Argon’s Current Report on Form 8-K, dated June 30, 2010, and Exhibits (e)(3) and (e)(4) to Argon’s Schedule 14D-9, dated July 8, 2010, and incorporated by reference into this Schedule 13D.

Item 5. Interest in Securities of the Issuer.

(a)-(b) Neither Boeing nor Merger Sub directly own any outstanding shares of Common Stock. However, as described in Item 4 (a)-(b) of this Schedule 13D, as a result of the Tender Agreements, Boeing and Merger Sub have the power to vote the Shares with respect to certain matters relating to the Merger as set forth in the Tender Agreements (see Item 4 of this Schedule 13D for details). The Shares currently consist of 7,584,090 shares of Common Stock, which represent approximately 34.4% of the outstanding shares of Common Stock as of July 6, 2010. The Significant Stockholders retain the sole power to vote the Shares on all matters other than those identified in the Tender Agreements. Pursuant to the Tender Agreements, and subject to limited exceptions set forth in the Tender Agreements, the Significant Stockholders may not (i) tender into any tender or exchange offer or otherwise directly or indirectly sell, transfer, pledge, assign or otherwise dispose of, or encumber with any lien, any of the Shares or any interest therein, (ii) deposit the Shares into a voting trust, enter into any other voting


CUSIP No.		040149106		Page		7		of		13

agreement or arrangement with respect to the Shares or grant any proxy or power of attorney with respect to the Shares, (iii) enter into any contract, option or other arrangement or undertaking with respect to the direct or indirect acquisition or sale, transfer, pledge, assignment or other disposition of any interest in or the voting of any Shares or any other securities of Argon or (iv) take any other action that would make any representation or warranty of the Significant Stockholder contained in the Tender Agreements untrue or incorrect in any material respect or in any way restrict, limit or interfere in any material respect with the performance of the Significant Stockholder’s obligations thereunder or the transactions contemplated by the Merger Agreement.

To Boeing’s and Merger Sub’s knowledge, no shares of Common Stock are beneficially owned by any of the persons named in Schedule I to this Schedule 13D, except for such beneficial ownership, if any, arising solely from the Tender Agreements.

Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by Boeing or Merger Sub that it is the beneficial owner of any of the Common Stock referred to herein for purposes of the Exchange Act, or for any other purpose, and such beneficial ownership is expressly disclaimed.

(c) Neither Boeing nor Merger Sub nor, to the knowledge of Boeing and Merger Sub, any director or executive officer of Boeing or Merger Sub named in Schedule I to this Schedule 13D, has effected any transaction in shares of Common Stock during the past 60 days, except as disclosed herein.

(d) Not applicable.

(e) Not applicable.

The description contained in this Item 5 of the transactions contemplated by the Merger Agreement and the Tender Agreements does not purport to be complete, and is qualified in its entirety by the terms and conditions of the Merger Agreement and the Tender Agreements, copies of which are filed, respectively, as Exhibits 2.1 and 2.2 to Argon’s Current Report on Form 8-K, dated June 30, 2010, and Exhibits (e)(3) and (e)(4) to Argon’s Schedule 14D-9, dated July 8, 2010, and incorporated by reference into this Schedule 13D.


Item 6.		Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

To the knowledge of Boeing or Merger Sub there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 of this Schedule 13D and between such persons and any person with respect to any securities of Argon other than the following:

(a) The Merger Agreement, under which, among other things, Merger Sub has commenced the Offer and following the Offer, Merger Sub will merge with and into Argon, as a result of which Argon will become a wholly owned subsidiary of Boeing. The information contained in Items 3 and 4 of this Schedule 13D is incorporated herein by reference.

(b) The Tender Agreements. The information contained in Items 3, 4 and 5 of this Schedule 13D is incorporated herein by reference.
