Item 5.02  Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers; Compensatory Arrangements of Certain Officers.

(d)           On January 3, 2007, the Board of Directors (the “Board”) of Alliant Techsystems Inc. (“ATK”) increased the number of directors of ATK from 10 to 11 and elected Mark H. Ronald to ATK’s Board effective January 15, 2007.  Mr. Ronald recently retired as Chief Operating Officer and a member of the Board of Directors of BAE Systems plc, and President and Chief Executive Officer of BAE Systems Inc., BAE Systems plc’s wholly-owned U.S. subsidiary.  Mr. Ronald is chairman of the advisory board of BAE Systems Inc.

The Board’s Nominating and Governance Committee recommended Mr. Ronald’s election to the Board.  The Board also appointed Mr. Ronald to the Audit Committee.

The Board has determined that Mr. Ronald is an independent director under the New York Stock Exchange Corporate Governance Standards.  There was no arrangement or understanding between Mr. Ronald and any other persons pursuant to which Mr. Ronald was selected as a director.  BAE Systems and ATK engage in business with each other from time to time but the transactions, individually and in the aggregate, have not involved a material amount of either company’s revenues and Mr. Ronald has had no direct or indirect material interest in those transactions.  The Board has also determined that Mr. Ronald meets the New York Stock Exchange’s financial literacy requirement for audit committee membership and qualifies as an “audit committee financial expert” under the rules of the Securities and Exchange Commission.

Mr. Ronald will have the same compensation and indemnification arrangements as the other non-employee directors who serve on ATK’s Board, which have previously been described in ATK’s filings with the Securities and Exchange Commission.

A copy of the press release announcing Mr. Ronald’s election is furnished as Exhibit 99.1 to this Current Report on Form 8-K.
