Huntington Ingalls Industries’ (HII) Ingalls Shipbuilding division launched the amphibious assault ship USS Tripoli (LHA-7) from its floating dry dock on Monday, May 1. The launch was accomplished 13 weeks ahead of the original construction schedule.
«Ingalls has been the Navy’s large-deck amphibia builder since the early 1970s», said Ingalls Shipbuilding President Brian Cuccias. «Our vast knowledge and experience in the design and construction of these great ships is paying dividends – not only for the American taxpayer, but also for the Navy-Marine Corps team and the sailors and Marines who will be operating these important warships in defense of our country».
Tripoli, the second of the America-class amphibious assault ships, was translated to the company’s floating dry dock on April 8 and, after some prep work on the ship’s hull, was launched on Saturday, April 29. The next ship in the class, USS Bougainville (LHA-8), is scheduled to start construction in late 2018.
Ingalls is currently 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 ships, USS America (LHA-6).
