Huntington Ingalls Industries Awarded $1.5 Billion for U.S. Navy’s Second Flight II San Antonio Class Amphibious Transport Dock, LPD 31

Huntington Ingalls Industries (HII) is awarded a $1.5 billion contract modification from the U.S. Navy for the detail design and construction of the second Flight II LPD 17 San Antonio class amphibious transport dock, LPD 31.

The ship will be built at HII’s Ingalls Shipbuilding division in Pascagoula, Mississippi and will be the 15th ship overall in the San Antonio class. Work is expected to be complete by February 2027.

Fiscal 2019 and 2020 shipbuilding and conversion (Navy) funding in the amount of $532.1 million will be obligated at award and will not expire at the end of the current fiscal year. The U.S. Department of the Navy (DoN)’s Naval Sea Systems Command (NAVSEA) in Washington, District of Columbia, is the contracting activity (N00024-18-C-2406).

“In building this 15th LPD, Ingalls experienced shipbuilders will continue this hot production line of great amphibious warships for our Navy/Marine Corps team,” Ingalls Shipbuilding President Brian Cuccias said. “We are all proud to be building these great ships, and will continue to deliver the most survivable and affordable ships possible for our customers and our nation.”

The $1.47 billion contract for the first Flight II ship, the future USS Harrisburg (LPD-30), was announced last year. The two contracted Flight II San Antonio class ships, LPD 30 and LPD 31, are an evolution of the dock landing platform that strengthens the Navy and Marine Corps’ needs in future warfare.

Utilizing the LPD 17 class’ proven hull, this LPD derivative is highly adaptable and, like the first 13 ships in the class, will be used to accomplish a full range of military operations—from major combat to humanitarian assistance and disaster relief. The ship’s versatility—from its well deck, flight deck and hospital facilities to its self-defense and survivability features—provides a viable platform for America’s global defense needs.

The LPD 17 Flight II vessels, initially called LX(R)-class amphibious warfare ships, are intended to replace the Navy’s current Whidbey Island-class and Harpers Ferry-class landing dock ships (LSD).

Ingalls has delivered 11 San Antonio-class ships to the Navy and has two more under construction. The future USS Fort Lauderdale (LPD 28) was launched last month and is expected to be delivered in 2021; the keel for future USS Richard M. McCool Jr. (LPD 29) was laid last year. These two vessels act as a “transitional ship” between the current LPD 17 San Antonio-class design and the Flight II design.

The start of fabrication on the first Flight II ship, LPD 30, is scheduled this year.

The San Antonio class is a major part of the Navy’s 21st-century amphibious assault force. The 684-foot-long, 105-foot-wide ships are used to embark and land Marines, their equipment and supplies ashore via air cushion or conventional landing craft and amphibious assault vehicles, augmented by helicopters or vertical takeoff and landing aircraft such as the MV-22 Osprey. The ships support a Marine Air-Ground Task Force (MAGTF) across the spectrum of operations, conducting amphibious and expeditionary missions of sea control and power projection to humanitarian assistance and disaster relief (HADR) missions throughout the first half of the 21st century.
