Huntington Ingalls Industries (HII)'s Ingalls Shipbuilding division received a $1.5 billion contract award on 3 April to design and build LPD 31. This will be the 15th in the San Antonio-class ship and the second of the "LPD 17 Flight II". The contract award was moved up some weeks to provide funds to suppliers.

Huntington Ingalls Industries (HII) announced last week that its Ingalls Shipbuilding division has received a $1.47 billion, fixed-price incentive contract from the U.S. Navy for the detail design and construction of the amphibious transport dock LPD 30. The ship will be the 14th in the San Antonio class and the first Flight II LPD.

The US Navy's next generation LPD 17 Flight II Class amphibious transport dock ships are moving forward in Main Propulsion Diesel Engine (MPDE) efficiency by installing the common rail fuel injection system on the ship's Pielstick-Colt 2.5V Sequentially Turbocharged (STC) engine.
