SCHEDULE 13D

Item 1. Security and Issuer.

      The title of the class of securities which is the subject of this report is common stock, par value $.10 per share (“Common Stock”) of Network Six, Inc. (“Network Six”). Network Six is a Rhode Island corporation that has its principal executive offices at 475 Kilvert Street, Warwick, Rhode Island 02886.

Item 2. Identity and Background.

      (a)-(c), (f) This statement is filed on behalf of TRW Inc. (“TRW”) and NSI Systems Inc., a wholly owned subsidiary of TRW (“Merger Sub”). The principal offices of TRW and Merger Sub are located at 1900 Richmond Road, Cleveland, Ohio 44124. TRW is incorporated under the laws of the State of Ohio and Merger Sub is incorporated under the laws of the State of Rhode Island. TRW is an international company that provides advanced technology products and services. The principal businesses of TRW and its subsidiaries are the design, manufacture and sale of products and the performance of systems engineering, research and technical services for industry and the United States Government in the aerospace, information systems and automotive markets. Merger Sub was incorporated to effect the Merger (as defined in Item 3). Attached and incorporated herein by reference is Schedule A, which sets forth certain information concerning the directors and executive officers of TRW and Merger Sub.

      (d)-(e) During the last five years, neither TRW, Merger Sub nor, to the best knowledge of TRW and Merger Sub, any of TRW’s or Merger Sub’s directors and executive officers has either (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors), or (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting activities subject to, federal or state securities laws or finding any violation of such laws.

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

      Pursuant to an Agreement and Plan of Merger dated as of June 6, 2001 (the “Merger Agreement”), among Network Six, TRW and Merger Sub, and subject to the conditions set forth therein (including approval by shareholders of Network Six), Merger Sub will merge with and into Network Six and Network Six will become a wholly owned subsidiary of TRW (such events constituting the “Merger”). Once the Merger is consummated, Merger Sub will cease to exist as a corporation and all of the business, assets, liabilities and obligations of Merger Sub will be merged into Network Six with Network Six remaining as the surviving corporation (the “Surviving Corporation”) and a wholly owned subsidiary of TRW.

      In connection with the execution of the Merger Agreement, Saugatuck Capital Company Limited Partnership III (the “Preferred Shareholder”), the beneficial owner of all 714,285.71 outstanding shares of Series A Convertible Preferred Stock of Network

(Page 4 of 16 Pages)

Six, par value $3.50 per share (the “Preferred Shares”), entered into a Purchase and Sale and Voting Agreement with TRW and Merger Sub dated as of June 6, 2001 (the “Preferred Agreement”). The holder of the Preferred Shares is entitled to one vote for every four shares held by it on each matter to be voted upon by the holders of Common Stock. Each Preferred Share may be converted at any time into Common Stock, on a basis of one share of Common Stock for four Preferred Shares, therefore, the Preferred Shareholder is deemed to beneficially own 178,571.42 shares of Common Stock.

      In the Preferred Agreement, the Preferred Shareholder agreed to (a) vote the Preferred Shares in favor of the Merger Agreement and the Merger and certain related matters and (b) sell the Preferred Shares to Merger Sub in exchange for: (i) a promissory note from Merger Sub, unconditionally guaranteed by TRW, in an aggregate principal amount of $2,500,000 and (ii) cash in an amount equal to all the accrued and unpaid dividends on the Preferred Shares. Such cash payment shall be based on (A) the rate provided for in Network Six’s Restated Articles of Incorporation through and including March 31, 2001 that remain unpaid at the time of such sale and (B) 6 percent per annum from March 31, 2001 through the date of such sale. The Preferred Shareholder also agreed that if, solely as a result of the consummation of the transactions contemplated by the Merger Agreement, a Change of Control (as defined in Network Six’s Restated Articles of Incorporation) of Network Six occurs before Merger Sub or TRW acquires the Preferred Shares from the Preferred Shareholder, Preferred Shareholder will not exercise its right and option to sell to Network Six all or a portion of the Preferred Shares for a price per share of $5.60 plus accrued and unpaid dividends to the date of such Change of Control, subject to its receipt of the consideration described above and the closing of the Merger. Subject to satisfaction or waiver of the conditions to closing contained in the Preferred Agreement, the purchase and sale of the Preferred Shares will occur immediately prior to the closing of the Merger. TRW did not pay additional consideration to the Preferred Shareholder in connection with the execution and delivery of the Preferred Agreement.

      In connection with the execution of the Merger Agreement, certain shareholders of Network Six who beneficially own in the aggregate 184,696 shares of Common Stock entered into an agreement with TRW and Merger Sub (the “Common Shareholder Voting Agreement”) whereby each such shareholder (collectively, the “Common Shareholders”) agreed, severally and not jointly, to vote all of the shares of Common Stock beneficially owned by them (including all shares which may be acquired by them prior to the termination of the Common Shareholder Voting Agreement, whether upon the exercise of Company Options or otherwise) in favor of the Merger Agreement and the Merger and certain related matters. TRW did not pay additional consideration to any of the Common Shareholders in connection with the execution and delivery of the Common Shareholder Voting Agreement.

      In connection with the execution of the Merger Agreement, certain employees and a trust affiliated with one employee (the “Employee Shareholders”) of Network Six beneficially owning in the aggregate 132,860 shares of Common Stock entered into an agreement with TRW and Merger Sub (the “Employee Shareholder Voting Agreement”) whereby each such Employee Shareholder agreed, severally and not jointly, to vote all of the shares of Common Stock beneficially owned by them (including all shares which may be acquired by them prior to the termination of the Employee Shareholder Voting Agreement, whether upon the exercise of Company Options or otherwise) in favor of the

(Page 5 of 16 Pages)

Merger Agreement and the Merger and certain related matters. TRW did not pay additional consideration to any of the Employee Shareholders in connection with the execution and delivery of the Employee Shareholder Voting Agreement.

      References to, and descriptions of, the Merger, the Merger Agreement, the Preferred Agreement, the Employee Shareholder Voting Agreement and the Common Shareholder Voting Agreement as set forth in this Schedule 13D are qualified in their entirety by reference to the Merger Agreement, the Preferred Agreement, the Employee Shareholder Voting Agreement and the Common Shareholder Voting Agreement, each included as Exhibits to this Schedule 13D.

Item 4. Purpose of Transaction.

      (a) - (b) As described in Item 3 above, this statement relates to the Merger of Merger Sub, a wholly owned subsidiary of TRW, with and into Network Six in a statutory merger pursuant to the applicable provisions of Rhode Island Law. Subject to the satisfaction or waiver of the conditions to closing set forth in the Preferred Agreement, Merger Sub will purchase the Preferred Shares from the Preferred Shareholder immediately prior to the Effective Time (as defined in the Merger Agreement) of the Merger, in exchange for the consideration for such shares described in Item 3. At the Effective Time, the separate existence of Merger Sub will cease and Network Six will continue as the Surviving Corporation and as a wholly owned subsidiary of TRW. Each holder of outstanding Common Stock will receive, in exchange for each share of Common Stock held by such holder, $3.60 in cash, without interest, subject to any dissenters’ rights. The Merger Agreement provides that each outstanding option to purchase Common Stock granted under Network Six’s stock option plans (“Company Options”) shall, as a result of the Merger, be fully exercisable and vested immediately prior to the Effective Time and all Company Options which are outstanding immediately prior to the Effective Time shall be cancelled and the holder of such Company Options shall be entitled to receive an amount, if any, equal to the excess of $3.60 per share over the exercise price per share thereof (net of applicable withholding taxes), provided that the holder of any such Company Option shall, as a condition to any such payment and prior to the Effective Time, deliver an executed Amendment to Stock Option Awards agreement.

      Pursuant to the Preferred Agreement, the Preferred Shareholder has agreed to vote its Preferred Shares at any Network Six shareholders meeting and in any action by consent of the shareholders of Network Six (a) in favor of the Merger and the Merger Agreement (as amended from time to time; provided that the Preferred Shareholder shall not be required to vote to approve the Merger if any amendment to the Merger Agreement materially adversely affects the Preferred Shareholder’s interest in the Merger, unless the Preferred Shareholder agrees to such amendment), (b) against any Takeover Proposal (as defined in the Merger Agreement) and certain other proposals and (c) in favor of any other matter necessary for consummation of the transactions contemplated by the Merger Agreement, and in connection therewith to execute any documents which are necessary or appropriate in order to effectuate the foregoing, including the ability for Merger Sub or its nominees to vote the Preferred Shares directly. The Preferred Agreement shall terminate (i) by the written mutual consent of the Preferred Shareholder, TRW and Merger Sub, (ii) by TRW or the Preferred Shareholder if the Merger shall not have been consummated on or before December 3, 2001;

(Page 6 of 16 Pages)

provided Network Six’s failure to perform any of its obligations under the Merger Agreement does not result in the failure of the Merger to be consummated by such date, or (iii) automatically upon the termination of the Merger Agreement in accordance with its terms.

      Pursuant to the Common Shareholder Voting Agreement, each of the Common Shareholders has agreed to vote the shares of Common Stock beneficially owned by it at any Network Six shareholders meeting and in any action by consent of the shareholders of Network Six (a) in favor of the Merger and the Merger Agreement (as amended from time to time; provided that no amendment shall reduce the consideration payable with respect to each share of Common Stock or change the nature of such consideration), (b) against any Takeover Proposal and (c) in favor of any other matter which the board of directors of Network Six proposes on the grounds that it is necessary for consummation of the transactions contemplated by the Merger Agreement, and in connection therewith to execute any documents which are necessary or appropriate in order to effectuate the foregoing, including the ability for Merger Sub or its nominees to vote the Common Stock directly. The Common Shareholder Voting Agreement shall terminate (i) by the written mutual consent of the Common Shareholders, TRW and Merger Sub, (ii) by TRW or any of the Common Shareholders (with respect to such Common Shareholder) if the Merger shall not have been consummated on or before December 3, 2001 or (iii) automatically upon the termination of the Merger Agreement.

      Pursuant to the Employee Shareholder Voting Agreement, each of the Employee Shareholders has agreed to vote the shares of Common Stock beneficially owned by it at any Network Six shareholders meeting and in any action by consent of the shareholders of Network Six (a) in favor of the Merger and the Merger Agreement (as amended from time to time), (b) against any Takeover Proposal and certain other proposals and (c) in favor of any other matter necessary for consummation of the transactions contemplated by the Merger Agreement, and in connection therewith to execute any documents which are necessary or appropriate in order to effectuate the foregoing, including the ability for Merger Sub or its nominees to vote the Preferred Shares directly. The Employee Shareholder Voting Agreement shall terminate (i) by the written mutual consent of the Employee Shareholders, TRW and Merger Sub, (ii) by TRW or any of the Employee Shareholders (with respect to such Employee Shareholder) if the Merger shall not have been consummated on or before December 3, 2001; provided Network Six’s failure to perform any of its obligations under the Merger Agreement does not result in the failure of the Merger to be so consummated by such time or (iii) automatically upon the termination of the Merger Agreement in accordance with its terms. Each Employee Shareholder that is the holder of Company Options also agreed to execute and deliver an Amendment to Stock Option Awards agreement.

      The Preferred Shareholder, each Common Shareholder and each Employee Shareholder has agreed that, during the term of the Preferred Agreement, the Common Shareholder Voting Agreement, or the Employee Shareholder Voting Agreement, as the case may be, it will not, and will not offer or agree to, sell, transfer, tender, assign, pledge, hypothecate or otherwise dispose of, or create or permit to exist any encumbrance on the shares covered by such agreement.

(Page 7 of 16 Pages)

      The Preferred Shareholder, each Common Shareholder and each Employee Shareholder also agreed to revoke any and all prior proxies or powers of attorney in respect of any of the shares covered by such agreement and constituted and appointed TRW and Merger Sub, or any nominee of TRW and Merger Sub, with full power of substitution and resubstitution, at any time during the term of the applicable agreement, as its true and lawful attorney and proxy (its “Proxy”), for and in its name, place and stead, to demand that the Secretary of Network Six call a special meeting of shareholders for the purpose of considering the Merger and related matters and to vote all of its Network Six shares as their Proxy, at every annual, special, adjourned or postponed meeting of shareholders, including the right to sign their name (as shareholder) to any consent, certificate or other document relating to Network Six that the law of the State of Rhode Island may permit or require in connection with any such matter.

      The Preferred Shareholder, each Common Shareholder and each Employee Shareholder agreed that, during the term of the applicable agreement, it would not solicit, initiate or encourage any inquiries or the making of any proposal relating to (i) any acquisition of all or any of the such shareholder’s Preferred Shares or Common Stock, as the case may be, or (ii) any transaction that constitutes a Takeover Proposal. Each such shareholder agreed to terminate any existing or prior discussions or negotiations with any person with respect to any of the foregoing and to notify Parent and Merger Sub promptly if any such proposal or offer, or any inquiry or contact with any person with respect thereto, is made and to indicate to Parent and Merger Sub in reasonable detail the identity of the person making such proposal, offer, inquiry or contact and the terms and conditions of such proposal, offer, inquiry or contact.

      The purpose of the transactions under the Preferred Agreement is to acquire the Preferred Shares and to help enable TRW to consummate the transactions contemplated under the Merger Agreement. The purpose of the transactions under the Common Shareholder Voting Agreement and the Employee Shareholder Voting Agreement is to help enable TRW to consummate the transactions contemplated under the Merger Agreement.

      (c) Not applicable.

Item 5. Interest in Securities of the Issuer.

      (a)-(b) TRW has sole dispositive and voting power with respect to no shares. As a result of the Preferred Agreement, the Common Shareholder Voting Agreement and the Employee Shareholder Voting Agreement, each of TRW and Merger Sub may be deemed to be the beneficial owner of 496,127.42 shares of Common Stock. This figure includes:

• 178,571.42 shares of Common Stock that the Preferred Shareholder has the right to acquire upon conversion, at its option, of the Preferred Shares;

• 184,696 shares of Common Stock beneficially owned by the Common Shareholders; and

• 132,860 shares of Common Stock beneficially owned by the Employee Shareholders, including 64,375 shares of Common Stock that certain Employee Shareholders have the right to acquire within 60 days pursuant to the exercise of Company Options.

      The shares of Common Stock as to which TRW and Merger Sub share voting and dispositive power pursuant to the agreements described herein constitute approximately 46.8% of the issued and outstanding shares of Common Stock based on the number of shares of Common Stock outstanding as of June 6, 2001, as calculated pursuant to Rule 13d-3 under the Securities Exchange Act and based on representations in the Merger Agreement by Network Six as to the number of shares of Common Stock outstanding on such date. TRW may be deemed to have shared power to vote and shared power to dispose of the shares with respect to those matters described above. TRW, Merger Sub, and the directors and executive officers of TRW and Merger Sub disclaim beneficial ownership of these shares.

(Page 9 of 16 Pages)

      To TRW’s knowledge, no person listed on Schedule A beneficially owns any securities of Network Six.

      Set forth on Schedule B are the names and principal business addresses of the shareholders of Network Six that have entered into the Preferred Agreement, the Common Shareholders Agreement and the Employee Shareholders Agreement with TRW, and, in each case as applicable, their present principal occupation or employment, including the name, principal business and address of any corporation or other organization in which such employment is conducted, their state or place of organization, and their citizenship, to TRW’s knowledge, which information is based on information disclosed by Network Six and such shareholders in their respective public filings with the Securities and Exchange Commission and on information provided by such parties to TRW. To the knowledge of TRW and Merger Sub, none of the persons or entities listed on Schedule B nor any executive officer, director or controlling person of any of them, has, during the last five years, been (i) convicted in any criminal proceeding excluding traffic violations or similar misdemeanors or (ii) a party to a civil proceeding or a judicial or administrative body of competent jurisdiction as a result of which it was or is subject to a judgment, decree or final order enjoining violations of, or prohibiting or mandating activities subject to, federal or state securities laws, or finding any violation with respect to such laws.

      (c) No transactions have been effected in the Common Stock of Network Six by TRW or Merger Sub or, to the best knowledge of TRW and Merger Sub, by TRW’s or Merger Sub’s directors and executive officers within the past 60 days.

      (d) To the knowledge of TRW, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the securities of Network Six reported on herein.

      (e) Not applicable.

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

      Other than the Merger Agreement, the Preferred Agreement, the Common Shareholder Voting Agreement and the Employee Shareholder Voting Agreement described herein and other than as set forth below in this Item 6, to the knowledge of TRW and Merger Sub, there are no contracts, arrangements, understandings or relationships among the persons named in Item 2 and between such persons and any person with respect to any securities of Network Six, including but not limited to transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.

      Concurrently with the execution and delivery of the Merger Agreement, TRW entered into a Voluntary Termination and Severance Agreement with James J. Ferry, Vice President of Finance and Administration, Chief Financial Officer and Treasurer of Network Six pursuant to which TRW agreed, among other things, to pay Mr. Ferry an amount equal to $3.60 per share multiplied by 15,000 (which is the number of Restricted Stock Units that Mr. Ferry would otherwise be entitled to upon consummation of the

(Page 10 of 16 Pages)

certain transactions, including the Merger), less applicable taxes. The agreement becomes effective upon the effectiveness of the Merger.

      Concurrently with the execution and delivery of the Merger Agreement, TRW entered into an Employment Agreement with Donna J. Guido, Vice President of Information Systems of Network Six pursuant to which TRW agreed, among other things, to pay Ms. Guido an amount equal to $3.60 per share multiplied by 15,000 (which is the number of Restricted Stock Units that Ms. Guido would otherwise be entitled to upon consummation of the certain transactions, including the Merger), less applicable taxes.
