During the last five years, none of the Reporting Persons has been (i) convicted in a criminal proceeding (excluding traffic violations and similar misdemeanors) or (ii) 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 or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

The business address of each of the Reporting Persons is 12400 High Bluff Drive, Suite 600, San Diego, CA 92130.

Item 3.    Source and Amount of Funds or Other Consideration

The Relational LPs purchased an aggregate of 4,598,720 Shares for total consideration (including brokerage commissions) of $372.3 million derived from the capital of the Relational LPs and margin borrowings from Credit Suisse Securities (USA) LLC (“CSSU”) for RFP, RCP, RH1, RI XX and RI XXIII.

Interest on the margin debt balance of the margin accounts described above is charged at the then Federal Funds Rate plus 50 basis points.  CSSU has a lien on the Shares held by RFP, RCP, RH1, RI XX and RI XXIII to secure repayment of the margin borrowings described above.

Item 4.    Purpose of Transaction

The Reporting Persons acquired the Shares reported in this Statement because, in their opinion, such Shares are undervalued by the market at the present time.

The Company’s Shares have underperformed the S&P 1500 Aerospace & Defense Index and the “core defense group,” as presented by the Company for comparative purposes in its Definitive Proxy Statement on Schedule 14A on March 14, 2011, over the last one-, three- and five-year periods.  The Shares have also underperformed the broader market S&P 500 Index over the last one- and three-year periods.

The Reporting Persons believe the Share discount is at least partially attributable to the Company’s sub-optimal business mix and the Company’s current strategy.  The Reporting Persons have discussed these issues from time to time with the Company’s management team and believe management is aware of the issues.  The Reporting Persons believe that the market will reward the Company with a higher share price to earnings multiple if the Company takes strategic and tactical actions to address its business mix.  Such actions could include the disposition or spin-off of underperforming or low-growth, low-margin assets. In particular, the Reporting Persons believe certain of the Company’s assets may lend themselves to acquisition by private equity participants where recent activity has been robust. Based on management’s recent public statements the Reporting Persons are gaining confidence that the Company’s board and management will better address these issues in an effort to increase shareholder value. The Reporting Persons note that several companies within the defense industry have recently benefited from taking such actions.

19

The Reporting Persons intend to closely monitor the Company’s performance, business mix and strategic direction and may modify their plans in the future depending on future events and any actions taken or omitted by the Company.  The Reporting Persons and their representatives and advisers intend to continue their discussions regarding the Company, its business mix, strategic direction, operations and capital allocation discipline with members of the board of directors and management of the Company.  In addition, the Reporting Persons and their representatives and advisers may communicate with other shareholders, industry participants and other interested parties concerning the Company.

Although the Reporting Persons do not have any current plans other than the monitoring and communication program outlined above, the Reporting Persons reserve the right to, and may in the future exercise any and all of their respective rights as shareholders of the Company in a manner consistent with their equity interests, including seeking representation on the Company’s board of directors at a special or annual meeting of the Company’s shareholders.

The Reporting Persons may from time-to-time (i) acquire additional Shares (subject to availability at prices deemed favorable) in the open market, in privately negotiated transactions or otherwise, or (ii) dispose of Shares at prices deemed favorable in the open market, in privately negotiated transactions or otherwise.

As of the date of this Statement, except as set forth above, none of the Reporting Persons has any present plan or intention which would result in or relate to any of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5.    Interest in Securities of the Issuer

(a)           As of the date of this Statement, the Reporting Persons beneficially owned in the aggregate 6,347,694 Shares, constituting 5.98% of the outstanding Shares.  The percentage of Shares owned is based upon 106,127,785 Shares outstanding on May 2, 2011, as set forth in the Issuer’s Form 10-Q for the quarter ended April 1, 2011.  The Reporting Persons may be deemed to have direct beneficial ownership of the Shares as follows:

RILLC, individually and in its capacity as an investment adviser, may be deemed to possess direct beneficial ownership of the 1,748,974 Shares that are owned by it and the Managed Accounts.  Additionally, RILLC, as the sole general partner, or sole managing member of the general partner, of each of the Relational LPs may be deemed to beneficially own (as that term is defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) the 4,598,720 Shares beneficially owned by the Relational LPs because the limited partnership agreements of the Relational LPs specify that RILLC has sole investment discretion and voting authority with respect to those Shares.

Each of Messrs. Whitworth and Batchelder, as Principals of RILLC, may be deemed to share indirect beneficial ownership of the Shares which RILLC may beneficially own.  Each of Messrs. Whitworth and Batchelder disclaims beneficial ownership of such Shares for all other purposes.

To the best of the knowledge of each of the Reporting Persons, other than as set forth above, none of the persons named in Item 2 is the beneficial owner of any Shares.

(b)           See item (a) above.

(c)           Except as set forth in Exhibit A to this Statement, none of the Reporting Persons has effected any transactions in the Shares during the past sixty days.

(d)           No other person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares covered by this Statement, except that dividends from, and proceeds from the sale of, the Shares held by accounts managed by RILLC may be delivered to such accounts.

(e)           Not applicable.

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

Except for the joint filing agreement between and among the Reporting Persons attached hereto as Exhibit B, and except for the investment discretion and voting authority described in Item 2 of this Statement and in the respective partnership agreements of the Relational LPs which each contain provisions whereby RILLC may, after certain adjustments, receive a percentage of realized or unrealized profits, if any, derived from that partnership’s investments, to the best of the knowledge of the Reporting Persons, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the Reporting Persons or between the Reporting Persons and any other person with respect to any securities of the Issuer, 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.
