The design of the America class is based on that of USS Makin Island, the last ship of the Wasp class, but the "Flight 0" ships of the America class will not have well decks, and they have smaller on-board hospitals in order to give more space for aviation uses. The vessel will replace the LHA 1 Tarawa Class of amphibious assault ships and will be able to lead an expeditionary strike group and also form part of th… The Congressional Budget Office found that if before 2040 the price of oil reached and remained above $140 per barrel then the use of nuclear propulsion for LH(X)-class ships would be more cost-effective. She can carry about 20 AV-8Bs or F-35Bs, and two MH-60Ss, to serve as a small aircraft carrier as demonstrated by landing helicopter dock (LHD) operations in Operation Iraqi Freedom. After 2000, the LHX, the so-called "Amphibious Assault Ship Future Replacement", was put forward to replace all of the LHDs. Bbb70081 1/700 Working Us Navy Wasp-Type Amphibious Assault Ship Metal Deck. About 45 percent of the "Flight 0" design of this class is based on that of Makin Island, but with her well deck omitted to allow more room for aircraft, their spare parts and weapons, and their fuel.

The gas turbines of Makin Island, America, and her possible successors use JP-5 fuel which is the same fuel used by their helicopters, the jet engines of their AV-8B Harrier and MV-22 Osprey aircraft and, in future ships, the gas turbines of the Landing Craft Air Cushions (LCACs) that they could carry in their well decks. For this Marines will be transported ashore in larger and longer range MV-22 V/STOL aircraft. Item Information. In place of a well deck, LHA 6 will have an extended hangar deck with two overhead cranes.  Setting the beam of America at 106 feet (32 m) was dictated by the need for these ships to pass through the Panama Canal.
