Ship Specifications – The America Class


Tripoli (LHA 7) is the second of the America-class amphibious assault ships built by Ingalls Shipbuilding for the U.S. Navy. The largest of all amphibious warfare ships, she is capable of supporting the most advanced Marine Corps aircraft. Amphibious warships such as LHA 7 provide the Marine Corps a superb means of ship-to-shore movement.

LHA 7 features several aviation capabilities enhanced beyond previous amphibious assault ships. These include 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. As the next generation “big-deck” amphibious ship, LHA 7 is optimized for aviation, capable of supporting current and future aircraft such as the tilt-rotor MV 22 and the Joint Strike Fighter (JSF).
