The Air Force said yesterday it awarded Lockheed Martin [LMT] a $830 million firm-fixed-price, cost-plus-fixed-fee contract modification for additional production of 18 F-16s for Iraq.

The modification also includes associated support equipment, technical orders, integrated logistics support, contractor logistics support and an electronic warfare system. Work is expected to be completed by April 30, 2014.

The contract modification is a foreign military sale (FMS) with $406.7 million obligated at the time of award. The contract modification was also a sole source acquisition.
