Huntington Ingalls Industries’ (HII) Ingalls Shipbuilding division has secured a $187.46m contract from the US Navy to provide long-lead-time material and advance procurement activities for amphibious assault ship LHA 9.

Ingalls is currently the only builder of large-deck amphibious ships for the US Navy.

Ingalls Shipbuilding president Brian Cuccias said: “This contract allows us to maintain the health of our critical nationwide shipbuilding supplier base while continuing our serial production of large-deck amphibs.

“We will work closely with our Navy-Marine Corps partners and our suppliers across the US to build another highly capable, versatile and survivable warship.”

In 1966, the shipyard delivered its first amphibious assault ship, the Iwo Jima-class USS Tripoli (LPH 10).

Since then, Ingalls built five Tarawa-class (LHA 1) ships, eight Wasp-class (LHD 1) ships and the first in a new class of amphibious assault ships, America (LHA 6) in 2014.

The third America-class large-deck amphibious landing helicopter assault (LHA 8) warship, which is to be named USS Bougainville vessel, is currently under construction.

In June 2017, the $3bn contract was awarded for the detail design and construction of the LHA 8 warship.

In March this year, the Shipbuilding division of HII delivered the newest America-class amphibious assault ship Tripoli (LHA 7) to the US Navy.
