USS America (LHA-6) will be the first of the America-class amphibious assault ships for the U.S. Navy. She will be delivered in 2013, replacing USS Peleliu (LHA-5) of the Tarawa class. Her mission is to act as the flagship of an expeditionary strike group or amphibious ready group, carrying a Marine Expeditionary Unit into battle and putting them ashore with helicopters and V-22 Osprey tilt-rotor aircraft, supported by F-35B Lightning II aircraft and helicopter gunships.

Her design is based on USS Makin Island (LHD-8) but with no well deck and smaller medical spaces to allow more room for aviation facilities. With a displacement of 45,000 tons she is as big as the aircraft carriers of other nations, and can fulfil similar missions when configured with 20 F-35B strike fighters.

[edit] Design

The design is based on the USS Makin Island (LHD-8), itself an improved version of the Wasp class amphibious assault ship. Approximately 45% of the Flight 0 design is based on LHD-8, with the well deck removed to allow more room for aircraft and aviation fuel.[6] Removal of the well deck for landing craft provides for an extended hangar deck with two significantly-wider high bay areas, each fitted with an overhead crane for aircraft maintenance.

These changes were required in order to operate the F-35B and MV-22 which are considerably larger than the aircraft they replace.[7] The typical aircraft complement is expected to be 12 MV-22B Osprey transports, 6 STOVL F-35B Lightning II attack aircraft, 4 CH-53K heavy transport helicopters, 7 AH-1Z/UH-1Y attack helicopters and 2 Navy MH-60S "Knighthawks" for air-sea rescue.[5] The exact makeup of the ship's aircraft complement will vary according to its mission. It can carry 20 F-35B and 2 MH-60S[5] to serve as a small aircraft carrier as demonstrated by LHD operations in Operation Iraqi Freedom.[2]

Other enhancements include a reconfigurable command and control complex, an on-board hospital, additional aviation fuel capacity, and numerous aviation support spaces.[8]

[edit] History

USS America is the fourth American warship to bear this name.[8] The U.S. Navy awarded Northrop Grumman Corporation's Ingalls Shipyard Division a $2.4 billion fixed-price incentive contract for the detailed design and construction of LHA-6, primarily at the company's shipyard in Pascagoula, Mississippi.[8] The production decision was made in January 2006[6] and construction of LHA-6 began in December 2008.[6] The keel-laying ceremony was on 17 July 2009[2] with delivery originally planned for August 2012.[6] As of 2009 delivery was planned for February 2013[6] and initial capability for February 2014,[6] but delivery has now been further delayed into FY2014.[9]
