The deckhouse of the US Navy’s America-class large-deck amphibious assault ship, USS Tripoli (LHA 7), has been successfully installed by Huntington Ingalls Industries’ (HII) Ingalls Shipbuilding division.

Carried out three weeks ahead of schedule, the installation marks the start of integration of the ship’s three largest sections.

LHA 7 programme director Premo Sabbatini said: “The deckhouse is comprised of five deck levels and includes radio and radar spaces, the primary flight control station, and the pilot house.

"The deckhouse is comprised of five deck levels and includes radio and radar spaces."

“The estimated lift weight for the deckhouse is 701 short tonnes and required three cranes to complete this task. Performing this milestone ahead of schedule is a testament to the hard work and dedication of our shipbuilders.”

In 2012, HII was awarded a $2.38bn fixed-price-incentive contract to design and construct USS Tripoli, which is expected to be delivered in 2018.

The 844ft–long, 106ft wide vessel will accommodate a total of 1,059 crew members, besides marine helicopters, MV22 Osprey tilt rotor aircraft and F35B joint strike fighter (JSF) aircraft.

USS Tripoli will feature an enlarged hangar deck, realignment and expansion of the aviation maintenance facilities, a significant increase in available stowage for parts and support equipment, and increased aviation fuel capacity.

The vessel will be deployed as the flagship for an Expeditionary Strike Group of the US Navy.

HII has been recently awarded a $272m contract for the planning, advanced engineering and procurement of long-lead material for LHA 8.
