        HMS Ocean

        'Britain’s biggest warship', HMS Ocean is currently in her home port of Devonport and in the midst of a scheduled period of maintenance. She returned in the latter part of last year from Greenwich, London, where she was moored for the duration of the London 2012 Olympic and Paralympic Games.

        More usually, as a helicopter carrier and amphibious assault ship, Ocean is designed to deliver troops to the centre of the action by helicopter or by landing craft – we have six helicopter operating spots on our flight deck and our hangar can hold many more aircraft. We have our own Royal Marine assault squadron, 9ASRM, and we also carry four Mk5 landing craft vehicle and personnel (LCVP).

        Built on the Clyde by Kvaerner Govan, Ocean was a new approach to naval shipbuilding using commercial-build methods and techniques. The ship was launched in October 1995, and named by Her Majesty the Queen on February 20 1998.

        We were commissioned in September 1998 in our homeport of Devonport – the heart of the Navy’s amphibious fleet. Until the arrival of the Queen Elizabeth class carriers, HMS Ocean is the largest warship in the Navy’s surface fleet.

        Ocean deployed as part of the Cougar deployment with the Response Force Task Group (RFTG) in April 2011.

        After working up with the group she was diverted to Libya where she conducted Strike operations using Apache attack helicopters from 4 Regiment Army Air Corps in support of the NATO mission Op Unified Protector. The Apaches have been ably assisted during the operation by other helicopters embarked in HMS Ocean. 

        These have included Sea King Mk 7 Airborne Surveillance and Control (SKASaC) helicopters of 857 Naval Air Squadron conducting maritime surveillance operations and Lynx Mk 7s of 847 Naval Air Squadron providing force protection and logistic support, as well as US Air Force HH60 Pavehawks. 

        The US airmen from the 56th Rescue Squadron based at RAF Lakenheath in Suffolk, were on standby for personnel recovery or medical evacuation operations in the event of incidents involving any NATO aircrafts or ships.

        HMS Ocean


        HMS Ocean HISTORY

        • The First Ocean

          This is the sixth ship to bear the name HMS Ocean, with a lineage going back to 1761. The first Ocean, a 90-gun second rate, began the name’s strong links with the West Country in 1770 when she became Flagship to Plymouth. As part of the Channel Fleet, Ocean saw her first real action against the French in 1778 under the lead of HMS Victory. She was sold out of the service in 1793.

        • The Second Ocean

          Ocean’s next incarnation was a second-rate 98-gun warship, she spent the bulk of her service in the Mediterranean, including a spell as Flagship of Vice Admiral Lord Cuthbert Collingwood. She was converted into a depot ship in 1841 and broken up in 1875.

        • The Third Ocean

          The next HMS Ocean was an ironclad of 50 guns. She holds the record for the longest days by any British ironclad under sail of 243 miles heading out to the Far East. She was Flagship of the Commander in Chief on the China Station from 1867 until paying off in 1872, she was eventually sold for scrap in 1882.

        • The Fourth Ocean

          The fourth Ocean earned a reputation as an unlucky ship, suffering various mishaps during build – including 90ft of the ship collapsing. She was one of the first British warships to journey along the Suez Canal and served on the China Station between 1901 and 1905 during which time she was unfortunate enough to be hit by a typhoon. In 1914 she joined the 8th Battleship squadron, and was later tasked to operations in the Dardanelles where her bad luck continued.

        • The Fourth Ocean

          In March 1915, as she attempted to rescue the mine-struck HMS Irresistible; realising the hopelessness of the situation, Ocean hit a mine – flooding, under fire, irreparable, she was abandoned and sank that evening.

        • The Fifth Ocean

          It was the fifth HMS Ocean that cemented her links with naval aviation. The Colossus-class aircraft carrier had a brief but active service career from her commissioning in July 1945. In October 1945 her deck saw the last Fairey Swordfish flight from a carrier; and in December she welcomed the first landing of a pure jet-powered aircraft. The 1950s saw her carrier in action during the Korean War, then on to the Suez Crisis where she took part in the first helicopter assault landing. She was scrapped in 1962
