QinetiQ North America (QNA) yesterday said that Duane Andrews, its CEO since 2006, is retiring at the end of March and will be succeeded by J.D. Crouch, who is currently president of the company’s Technology Solutions Group.

Crouch, who became president of the Technology Solutions Group in 2009, previously was QNA’s executive vice president for Strategic Development. He has also serviced as deputy national security adviser under President George W. Bush, U.S. Ambassador to Romania, assistant secretary of defense for International Security Policy, and co-founded and served as chief marketing officer of PalmGear.com, the Palm OS App Store.

In a statement Crouch said “I believe we are well positioned to take the business to the next level of its development and growth.”

Andrews, 68, joined QNA after a 13-year career at SAIC [SAI], where he served in several executive roles, including executive vice president and chief operating officer, president and COO of the company’s Federal Business segment, and executive vice president for Corporate Development.

Andrews oversaw a number of acquisitions in the United States by QNA to help extend the presence here of the company’s parent, QinetiQ, which is based in Britain.
