The Wasp-class is a class of landing helicopter dock (LHD) amphibious assault ships operated by the United States Navy. Based on the Tarawa class, with modifications to operate more advanced aircraft and landing craft, the Wasp-class is capable of transporting almost the full strength of a United States Marine Corps Marine Expeditionary Unit (MEU), and landing them in hostile territory via landing craft or helicopters as well as providing air support via AV-8B Harrier II attack aircraft or F-35B Lightning II stealth strike-fighters. All Wasp-class ships were built by Ingalls Shipbuilding, at Pascagoula, Mississippi, with the lead ship, USS Wasp, commissioned on 29 July 1989. Eight Wasp-class ships were built, and as of April 2021^[update], seven are in active service, as USS Bonhomme Richard was seriously damaged by fire on 12 July 2020, and subsequently decommissioned in April 2021.^[4][5]
