Huntington Ingalls Industries’ (HII) Ingalls Shipbuilding division has been selected to perform the majority of the contract design work for the U.S. Navy’s amphibious warfare ship replacement, known as LX(R). The Department of Defense made the announcement Thursday, on June 30, 2016, at the same time Ingalls was awarded a contract to build the next large-deck amphibious assault warship, LHA-8.
LX(R) will replace the Navy’s Harpers Ferry- and Whidbey Island-class dock landing ships and will use the same hull as the San Antonio (LPD-17) class. Ingalls has delivered 10 of the LPD-17 ships to the U.S. Navy, is currently building the 11th, USS Portland (LPD-27), and has received more than $300 million in advance procurement funding for the 12th, USS Fort Lauderdale (LPD-28).
«With a hot production line, skilled workers, a strong supplier base and deep experience building San Antonio-class LPD amphibious warships, Ingalls stands ready to close the gap between LPD-28 and LX(R), the next generation amphibious warships the Navy-Marine Corps team needs today», Ingalls Shipbuilding President Brian Cuccias said.
