The Department of Defense announced a series of small (in defense contracting terms) contract awards to a handful of publicly traded companies Wednesday.

Among them:

Raytheon (NYSE:RTN) was awarded an $8.3 million cost-plus-fixed-fee modification to an existing basic ordering agreement. It will perform "program management, design engineering, system engineering, technical analysis, programmatic and technical documentation development, safety-related engineering, and logistic support" on AN/SPS-73(V) surface search radar systems operated by the U.S. Navy and Coast Guard. This contact runs through April 2015.

United Technologies (NYSE:UTX) subsidiary Sikorsky Aerospace Maintenance won an $8.2 million modification to a previously awarded firm-fixed-price contract to perform depot-level maintenance on Naval aircraft operated by "adversary squadrons" through June 2013. Adversary squadrons comprise U.S. pilots flying -- importantly -- either foreign-built planes (such as Russian MiGs), or older U.S. planes no longer in active service, flown in a style similar to those demonstrated by foreign air forces. The unusual "air forces" involved in this training require specialized knowledge in how to maintain their planes.

Rockwell Collins (NYSE:COL) won a $7.3 million modification to a previously awarded firm-fixed-priced contract for purchase of ARC electronic radio controls and ancillary equipment for Air Force F-15C/D aircraft. Delivery is expected by March 2014.
