On Thursday, the Department of Defense announced a series of small (in defense contracting terms) contract awards to a handful of publicly traded companies.

Among them are the following:

The largest contract went to Lockheed Martin (LMT -0.27%), which was awarded $27.4 million via an "option" extension of an existing contract. The option funds Lockheed's purchase of long-lead materials needed to perform receiver and antenna upgrades on AN/SLQ-32(V) Electronic Warfare Systems. This work is classified as part of the Surface Electronic Warfare Improvement Program (SEWIP) Block 2. Work on the instant contract modification is to be completed by March 2014.

ManTech International (MANT) won a $15.3 million contract modification to perform unspecified "systems engineering and integration support" work for the Space and Missile Systems, Launch and Range Systems directorate. This contract is to be completed by March 22, 2014. 

Finally, General Dynamics' (GD 0.48%) Armament and Technical Products division was awarded $7 million to supply 19 M61A2 20mm Lightweight Gatling Gun Systems for installation on F/A-18 E/F fighter aircraft. Completion date is March 2015.
