The World's 9 Most Successful Amphibious Assault Ships: The Incredible Power of Number 3

2. HMS Ocean (L12)

Acting as the Royal Navy's flagship before its decommissioning and sale to Brazil, HMS Ocean proved extraordinary adaptability in world operations. Supporting helicopter operations in several environments, this helicopter carrier and assault ship could carry 800 personnel and their gear. Its value in both military and civilian activities was demonstrated by its successful deployments during many NATO exercises and humanitarian relief during Hurricane Irma. The flexible design of the ship shaped next amphibious assault vessel improvements all around. Over two decades, HMS Ocean's outstanding career involved multiple high-profile operations including the 2011 military intervention in Libya and several counter-piracy missions in the Gulf of Aden. From the Arctic Circle to tropical seas, the vessel's remarkable engineering and adaptability was evident. While its hangar could contain up to twelve aircraft, so offering great aviation potential for both military and humanitarian operations, its flight deck could allow five operational positions for helicopters. During catastrophe relief efforts, the ship's extensive medical facilities—which included a 20-bed sickbay and emergency operating theater—turned out rather helpful. Particularly in areas of crew comfort, operational flexibility, and mission adaptability, its legacy shapes current amphibious assault ship design.
