The company said a $106 million modification covers Battlefield Airborne Communications Nodes on three E-11A aircraft and three EQ-4B Global Hawk unmanned aerial vehicles.
That award supports operations through June 2013.
Under a $50 million award, the company will provide platform maintenance support on three E-11A aircraft through February 2013.
The company is the prime contractor for the Global Hawk and the development, fielding and maintenance of the BACN system.
Earlier this month, the Air Force said it was planning to award the company an estimated $782.5 million modification to continue operating BACN payloads between June 2012 and September 2015.
The U.S. first deployed BACN payloads to Afghanistan in 2008.
