The sixth HMS Ocean (L12) of the Royal Navy is a Landing Platform, Helicopter carrier, the only one in its class. It was built during the early part of the 1990s by Kvaerner Govan on the Clyde, taking advantage of commercial build methods and facilities, before sailing from Barrow-in-Furness for fitting out prior to acceptance into service with the Royal Navy. She is based on the Invincible class aircraft carrier design, but due to the commercial build used, the construction cost of £154 million is comparable to that of a Type 23 frigate.
Sea - Military - Other
Ocean was designed to provide the amphibious assault capabilities last offered by HMS Albion and Bulwark, carrying an Embarked Military Force (EMF) supported by 12 medium support helicopters, six attack helicopters, and four Mk5 landing craft. Her secondary roles included afloat training, limited anti-submarine warfare, and providing a base for anti-terrorist operations.
