The Department of Defense awarded 16 separate defense contracts on Wednesday worth $255.4 million in total. Boeing (NYSE:BA) won two of them, both benefiting the U.S. Navy.

The larger of the two awards, a $26.9 million contract modification, exercises an option to have Boeing partially redesign Lot 1 of its P-8A Poseidon sub-hunting aircraft to account for "diminishing manufacturing sources." Work on this project should be completed by April 2017.

Boeing also won a smaller, related award valued at $10.1 million. This was a firm-fixed-price requirements contract to repair 559 unspecified items required to support the Poseidon aircraft. These repairs are to be completed sooner -- by Sept. 30, 2015.
