The U.S. Department of Defense announced no fewer than 35 separate contract awards, worth a combined $1.78 billion, on Friday. Of these, the single largest contract awarded went to a joint venture among GP Strategies' (NYSE:GPX) General Physics Corporation, Computer Sciences Corporation (NYSE:CSC), and privately held Jacobs Sverdrup Construction, doing business as Aerospace Testing Alliance (ATA).

This contract, worth $218.6 million, is characterized as a "modification" of a cost-plus-award-fee contract previously awarded to ATA for its work in operating, maintaining, and performing information management services in support of the Arnold Engineering Development Complex (AEDC) at Arnold Air Force Base in Tennessee.

ATA has been working on this contract since at least 2004, assisting the Air Force in testing and evaluating weapons and aerospace systems ranging from the Pratt & Whitney F119 jet engine, to the ATK GASL supersonic scramjet, to the Boeing F-15K fighter jet being marketed to the Koreans, to the new Boeing F-15SA configuration ordered by the Royal Saudi Air Force.

Friday's contract modification will extend ATA's contract through Sept. 30, 2014.
