Design

The design of Bougainville is based on USS Makin Island, which is an improved version of the Wasp-class amphibious assault ship. While Makin Island has a well deck, the earlier two Flight 0 America-class ships USS America and USS Tripoli were designed and built without a well deck to make space for aircraft and aviation fuel.[10] Bougainville will be the first Flight I America-class ship,[1] and as such will include a well deck.[2] The design of the Flight I America-class ships, including that of Bougainville, adopts a compromise, incorporating a slightly smaller aircraft hangar as well as smaller medical and other spaces to fit a small well deck for surface connector operations.[2][11] The island structure will also be modified to free up more room on the flight deck to accommodate maintenance of V-22s, compensating for some of the lost aircraft hangar space.[11]

Bougainville will be the first of her class built with a redesigned and stronger main deck; the earlier America-class vessels America and Tripoli each required retrofitting in order to handle the strain of daily F-35B Lightning II flight operations.[12] In addition, Bougainville will incorporate the AN/SPY-6 Enterprise Air Surveillance Radar (EASR) volume air search radar in lieu of the AN/SPS-48G air search radar in America and Tripoli.[6] The Gerald R. Ford-class aircraft carriers starting with John F. Kennedy and the planned LX(R)-class amphibious warfare ships will also have this radar.[13]

Construction and career

Bougainville is being built by Huntington Ingalls Industries at their shipyard in Pascagoula, Mississippi[3] and is expected to be delivered to the U.S. Navy in 2024.[1]

Bougainville officially started fabrication on 16 October 2018.[5] The ship was first laid down on 14 March 2019.[14]
