US Navy launches USS Tripoli amphibious assault ship
The US Navy has launched its future America-class amphibious assault ship USS Tripoli (LHA 7) after completing the transition from land to the dry dock at Huntington Ingalls Industries' (HII) shipyard.
USS Tripoli required 247 units of jacking and pallet cars to complete the move, in order to support the displacement of the vessel and ensure even distribution throughout.
HII successfully completed the large-deck vessel translation after 19 hours of continuous work.
LHA Supervisor of Shipbuilding, Gulf Coast (SUPSHIP-GC) programme manager's representative commander Randy Slaff said: “It was probably the most well-executed translation event that we've seen on a larger ship.”
The US Navy’s USS Tripoli was successfully launched after the dry-dock was flooded to submerge the vessel, enabling it to float off for the first time.
Programme Executive Office (PEO) Ships Amphibious Warfare deputy programme manager captain Scot Searles said: “We've made tremendous progress on Tripoli over this past month, completing two major production milestones.
“Moving and launching a ship of this size is tedious work and our teams did a superb job executing.”
The amphibious assault ship will be equipped with an enlarged hangar deck, increased fuel capacity, improved maintenance facilities and additional storerooms to provide the vessel with an optimised platform for aviation capabilities.
USS Tripoli is expected to be christened later this year, with delivery to the US Navy currently planned for late 2018.
The navy awarded the original $2.38bn contract to HII for the detail design and construction of the future USS Tripoli (LHA 7) in May 2012, which took place at the company’s Ingalls Operations in Pascagoula, Mississippi.
