HMS Fearless' primary role is as "landing platform dock". In this role, HMS Fearless can transport a military force complete will full supporting armour. Landing craft capable of carrying heavy tanks are housed in the ship's internal dock and are launched from the open stern. The ship can also operate a flight of assault helicopters and defend itself with the Phalanx automated gun system. HMS Fearless is also fitted out as a Naval Assault Group/Brigade HQ from which naval and military personnel, working in close co-operation, can mount and control a joint amphibious operation.

HMS Fearless will be replaced in 2002 with the new LPDs Albion and Bulwark. These new ships will provide a significant increase in carrying improved landing craft and with a state of the art Combined Operations Room complex.
