On Friday, the U.S. Department of Defense announced it has awarded Lockheed Martin (LMT -0.55%) a pair of new contract "modifications" worth nearly $90 million in total.

The larger of the two awards ups Lockheed's contract for 2013 Contractor Logistics Support, Legacy Sustainment, and Combined Task Force Support by $75.2 million, resulting in a cumulative contract value of $181.1 million. Lockheed will be working on the Space Based Infrared System (SBIRS) Survivable Endurable Evolution, Increment 1, implementing "permanent sustainment modifications" to the system's Mobile Ground System. The aim here is to enable ground systems to process Defense Support Program and SBIRS geosynchronous orbit satellites mission data, and to also issue "limited contingency" commands to the satellites, when needed. Lockheed's work on the contract will continue through January 31, 2017.

The smaller award, to Lockheed's Integrated Systems unit, is worth $14.4 million, and extends Lockheed's logistics support for Iraq's C-130E Hercules transport aircraft for a fourth option year, through June 30, 2014. Total contract value on this one is now up to $61.6 million.
