America-class (LHA) | U.S. Navy's Next Generation "Big-Deck" Amphibious Assault Ships In Action

Amphibious warships are designed to support the Marine Corps tenets of Operational Maneuver From the Sea (OMFTS) and Ship to Objective Maneuver (STOM). They must be capable of sailing in harm's way and enable rapid combat power buildup ashore in the face of opposition. Because of their inherent capabilities, these ships have been and will continue to be called upon to also support humanitarian and other contingency missions on short notice. The United States maintains the largest and most capable amphibious force in the world.

LHAs are the largest of all amphibious warfare ships, resembling a small aircraft carrier. They are capable of Vertical/Short Take-Off and Landing (V/STOL), Short Take-Off Vertical Landing (STOVL), Vertical Take-Off and Landing (VTOL) tilt-rotor and Rotary Wing (RW) aircraft operations. LHA Flight 0 will enhance Marine Corp aviation with greater maintenance capability and JP-5 fuel capacity in lieu of a well deck. LHA Flight 1 will reincorporate a well deck to enhance expeditionary war fighting capabilities while maintaining the principal aviation characteristics of the Flight 0.
