Ocean-class Amphibious Assault Ship

The Ocean-class Amphibious Assault Ships are a pair of amphibious warfare vessels in service in the Royal Navy from the mid-1990s onwards. The Ocean-class ships are designed to support amphibious landing operations and to support the staff of Commander UK Amphibious Force and Commander UK Landing Force. They were constructed in the mid-1990s by Kvaerner Govan Ltd on the Clyde and fitted out by VSEL at Barrow-in-Furness prior to first of class trials and subsequent acceptance in service. They are complemented by a quartet of Albion-class LPDs.
