The U.S. Navy has given Lockheed Martin a $28.8 million contract for "retrofit modifications" on F-35A fuel tanks.

Under the contract, valued at over $28.8 million, Lockheed Martin will provide "retrofit modifications associated with the F-35A fuel tank overpressure engineering change proposal." The work will support F-35A customers Australia, Italy, the Netherlands, and Norway. All participating governments are original partner countries in Lockheed Martin's F-35 program, which also include Canada, Denmark, and Turkey.

Work on the contract will be performed at Lockheed Martin's facilities in Texas, Utah and California. The services are expected to be completed by March 2017.

The contract combines the purchases of the U.S. Air Force, which foots over 90 percent of the bill, and the governments of the Netherlands, Australia, Italy and Norway.
