LONG BEACH, Miss. (AP) — A Mississippi company is getting a chunk of a $58.5 million contract to design, build and demonstrate a prototype unmanned trimaran for anti-submarine warfare.

The Defense Advanced Research Projects Agency awarded the contract Wednesday to Science Applications International Corp. of McLean, Va.

According to a news release from the Pentagon, the work is being divided among 13 offices around the country. It says the one in Long Beach, Miss., is getting 13.4 percent. That's the third-largest percentage and works out to about $7.8 million.

Offices in Arlington, Va., and Vancouver, Wash., will each get more than 25 percent.

The Pentagon says the work is expected to be complete by Aug. 15, 2015.
