Earlier on Sept. 9, the ship was moved from land to the company's floating dry dock with the aid of translation railcars. Once in the dry dock, final preparations for the launch were executed by the Ingalls team.

Notably, Bougainville is the inaugural ship in its class to feature a well deck. While retaining its aviation capabilities, the ship has been enhanced with the surface assault potential of a well deck and an expanded flight deck designed for F-35B Joint Strike Fighter and MV-22 Osprey aircraft. Additionally, the ship boasts state-of-the-art medical facilities, complete with comprehensive operating suites and triage capabilities.
