The Fearless class amphibious assault ships were the first purpose-built amphibious warfare vessels in the Royal Navy. The class comprised two ships: HMS Fearless and HMS Intrepid. Designed as Landing Platform Docks, they were designed to transport and land troops by sea either using Landing Craft Utility or helicopters. As constructed, the ships have an internal dock that is accessed via the stern—while in port, vehicles can drive up the stern ramp and into the internal vehicle decks. At sea, the ships could partially submerge themselves at the stern, flooding the internal dock and allowing landing craft to come right up to the edge of the vehicle deck.
