The America-class amphibious assault ship is designed specifically to meet future Navy-Marine Corps requirements, able to support the expanded capability of 21st century expeditionary strike platforms such as the MV-22 Osprey helicopter and the F-35B Joint Strike Fighter airplanes. LHA 6, the first ship of the LHA(R) program, will be able to operate and support a detachment of 20+ Joint Strike Fighters. LHA 6 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.

LHA 6 will be multi-functional and versatile, modifying existing Command, Control, Communications, Computers and Intelligence (C4I) spaces to allow for flexible mission dependent reconfiguration. LHA 6 will also have increased cargo magazine capacity, better survivability, and greater service life margins.

LHA 6 will use the same gas turbine propulsion plant, zonal electrical distribution and electric auxiliary systems being designed and built for LHD 8, the final of the Wasp class amphibious assault ships.
