HMS Ocean
An amphibious assault ship, HMS 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) back in April.
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 Airbourne 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.
