Assault Ship

Huntington Ingalls Industries (HII) announced on June 17, 2020 that its Ingalls Shipbuilding division has received a third contract modification from the U.S. Navy for $145 million to provide long-lead-time material and advance procurement activities for amphibious assault ship LHA-9. This modification brings the total advance funding for LHA-9 to $350 million.

«This advance procurement contract will help protect the health of our supplier base and strengthen our efforts to efficiently modernize the nation’s amphibious fleet as we continue to build amphibious ships for the U.S. Navy», Ingalls Shipbuilding President Brian Cuccias said.

Ingalls is the sole builder of large-deck amphibious ships for the U.S. Navy. The shipyard delivered its first amphibious assault ship, the Iwo Jima-class USS Tripoli (LPH-10), in 1966. Ingalls has since built five Tarawa-class (LHA-1) ships, eight Wasp-class (LHD-1) ships and the first in a new class of amphibious assault ships, USS America (LHA-6), in 2014. The second ship in that class, USS Tripoli (LHA-7), was delivered to the U.S. Navy earlier this year. USS Bougainville (LHA-8) is under construction.

Huntington Ingalls Industries is America’s largest military shipbuilding company and a provider of professional services to partners in government and industry. For more than a century, HII’s Newport News and Ingalls shipbuilding divisions in Virginia and Mississippi have built more ships in more ship classes than any other U.S. naval shipbuilder. HII’s Technical Solutions division supports national security missions around the globe with unmanned systems, defense and federal solutions, nuclear and environmental services, and fleet sustainment. Headquartered in Newport News, Virginia, HII employs more than 42,000 people operating both domestically and internationally.
