PCU America (LHA-6), the fourth American warship to be named for the United States of America,[11] will be the first of the America-class amphibious assault ships for the U.S. Navy. As of 2014 she will be delivered in spring of 2014,[12] 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 part of 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.

The ship's design is based on USS Makin Island (LHD-8), but to allow more room for aviation facilities she does not have a well deck, and has smaller medical spaces. With a displacement of 45,000 tons, she is as large as the aircraft carriers of many other nations, and can fulfil similar missions when configured with 20 F-35B strike fighters.

Design[edit]

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.[13] The removal of the well deck for landing craft allows 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.[14] The typical aircraft complement is expected to be 12 MV-22B transports, six STOVL F-35B attack aircraft, four CH-53K heavy transport helicopters, seven AH-1Z/UH-1Y attack helicopters and two Navy MH-60S for air-sea rescue.[10] 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[10] 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.[11]

History[edit]

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.[11] The production decision was made in January 2006[13] and construction of LHA-6 began in December 2008.[13] Navy Secretary Donald C. Winter announced in June 2008 that the ship would be named America.[15] The keel-laying ceremony was held on 17 July 2009[2] with delivery originally planned for August 2012.[13] The ship was launched on 4 June 2012,[3] and christened on 20 October.[4] As of 2014, America is scheduled for delivery in the spring of 2014, with Naval Base San Diego as her home port.[4][12] She took to the sea for the first time on 5 November 2013, for five days of builder's sea trials in the Gulf of Mexico,[8] and completed acceptance sea trials in February 2014.[12]

America departed in commission without ceremony from Ingalls Shipbuilding in Pascagoula, Mississippi, on 11 July 2014 in transit to its homeport of San Diego, California. She is scheduled to be formally commissioned during Fleet Week in San Francisco, California, on 11 October 2014. The ship earned commission status after the crew successfully completed the light-off assessment, anti-terrorism force protection certification and crew certification. America is scheduled to transit U.S. Southern Command's area of responsibility during the transit, referred to as "America Visits the Americas". The ship will visit Naval Station Guantanamo Bay (Cuba), Colombia, Brazil, Chile and Peru.[16]
