HMS Ocean of the Royal Navy is an amphibious assault ship (or landing platform helicopter), the sole member of her class. She is designed to support amphibious landing operations and to support the staff of Commander UK Amphibious Force and Commander UK Landing Force. She is currently the largest ship in the Royal Navy.

She was constructed in the mid 1990s by Kvaerner Govan Ltd on the Clyde and fitted out by VSEL at Barrow-in-Furness prior to first of class trials and subsequent acceptance in service. She was commissioned in September 1998 at her home port Devonport, Plymouth.

Construction

An invitation to tender for a new helicopter carrier was issued in February 1992. In February 1993 The Times reported that the carrier faced cancellation due to budgetary constraints. However, at approximately the same time, British forces were engaged in operations in the Balkans, which saw the Royal Fleet Auxiliary's aviation training ship RFA Argus pressed into service as an LPH. Argus proved totally unsuitable in terms of accommodation and facilities needed for a large Embarked Military Force (EMF), which emphasised the need for a purpose built platform. On 29 March 1993 the defence procurement minister announced that development of the new LPH was proceeding.

Two shipbuilders competed for the contract - Vickers Shipbuilding and Engineering Ltd (VSEL) and Swan Hunter. On 11 May 1993 the government announced VSEL had won the contract. The build was to commercial standards, reducing costs significantly and leading to a construction spend of £154 million (£234 million as of 2012),, comparable to that of a Type 23 frigate. VSEL, a warship manufacturer, sub-contracted the build phase to the commercial Kværner yard in Govan, Glasgow.

The fact that VSEL's bid was £71 million lower than Swan Hunter's was the source of political controversy and led to a National Audit Office investigation to determine whether the competition was fair. The report, published on 29 July 1993, stated that although VSEL did subsidise its bid the MoD was right to award the contract to VSEL because the subsidy was much smaller than the difference between the two bids; VSEL's bid was £139.5 million compared to Swan Hunter's £210.6 million. The Times also suggested that the subsidy was as little as £10 million. In anticipation of the report the Financial Times described the different philosophies adopted by the two bidders; While Swan Hunter viewed the ships as entirely military, "VSEL thought the design was basically a merchant ship with military hardware bolted on." VSEL's decision to sub-contract the build phase took advantage of lower overheads at a civilian yard as well as efficiency drives by its parent, Kværner. The cut-price build to commercial standards means that Ocean has a projected operational life of just 20 years, significantly less than that of other warships.

Launched on 11 October 1995, she was subsequently named at Barrow by Her Majesty the Queen on 20 February 1998, prior to delivery to Devonport.

In her sea trial she managed to reach a top speed of 20.6 knots, however her usual top speed is 18 knots now totally fitted out and with the addition of new equipment.

Service history

While Ocean was undertaking the warm water element of her first-of-class trials, she provided humanitarian assistance in Honduras following Hurricane Mitch. During 2000 Ocean supported Operation Palliser in Sierra Leone, joining Illustrious aiding the suppression of rebel activity with her own EMF and providing support facilities for the Spearhead battalion ashore.

On 17 February 2002, a unit of Royal Marines from Ocean accidentally landed in the San Felipe beach in the Spanish town of La Linea instead of Gibraltar causing a minor diplomatic incident as various media outlets labelled the mistake as an "invasion".

Ocean was part of a large Royal Navy task force deployed for Operation Telic, the UK contribution to the 2003 Iraq War. In the helicopter assault role she was accompanied by Ark Royal.

In the summer of 2006, she was deployed as part of the task force involved in the Aurora exercises on the eastern seaboard of the United States.

In 2007, Ocean began her first long refit period. This was carried out by Devonport Management Limited at their Devonport Royal Dockyard facility and lasted around twelve months, during which period, Ark Royal took over the LPH role. Ocean sailed from Plymouth on Wednesday 24 September 2008 to start sea trials, following this major period of maintenance and upgrading work. As part of that upgrade a PyTEC pyrolysising waste recycling unit was fitted.

On 18 February 2009, Ocean sailed from Devonport as part of the Taurus 09 deployment under Commander UK Amphibious Task Group, Commodore Peter Hudson. She was joined on this deployment by landing platform dock Bulwark, as Hudson's flagship, Type 23 Frigates Argyll and Somerset and four ships of the Royal Fleet Auxiliary.

In June 2009, she took part in exercise Bersama Shield with Somerset and RFA Wave Ruler off the Malay Peninsula.

During the air travel disruption after the 2010 Eyjafjallajökull eruption Prime Minister Gordon Brown assigned Ocean and other units to rescue stranded travellers and army personnel across the English Channel in Operation Cunningham.

In 2010 she was deployed on a multi-purpose deployment. This started with exercise Auriga on the eastern coast of the USA. She then moved to Brazil to conduct exercise with the Brazilian marines, whilst there a defence cooperation agreement was signed onboard. She then crossed the Atlantic heading for Nigeria to both participate in the Nigeria at 50 presidential fleet review and capacity building with the Nigerian navy as part of the African partnership progamme.

In April 2011, She was deployed as the follow on ship for the RN's Response Force Task Group (RFTG) COUGAR 11 deployment. During this deployment, she took part part in Exercise Cypriot Lion

In May 2011, she was detached from the COUGAR 11 deployment of the Response Force Task Group and sent with embarked Apaches to aid operations in Libya along with the attack helicopters aboard the French amphibious assault ship Tonnerre. This marks the first time Apache helicopters have been sent into action from a Royal Navy ship. Her initial complement of three Apaches was bolstered by a fourth soon after, and later a fifth.

During the London 2012 Olympic Games, she will be moored in Greenwich to provide logistics support, accommodation and a helicopter landing site

Role

Ocean was designed to provide the amphibious assault capabilities last offered by Albion and Bulwark whilst in the Commando role. She can deploy an Embarked Military Force (EMF) of a Royal Marines Commando Group from 3 Commando Brigade supported by aviation and landing craft assets. The ships company includes 9 Assault Squadron from 1 Assault Group Royal Marines.

Ocean is also capable of limited anti-submarine warfare activities, supporting afloat training and acting as a base facility for other embarked forces including counter-terrorism units.

Aviation

The air group of up to 12 Sea King HC4 medium-lift helicopters, six Lynx AH7 light-lift/anti-tank helicopters are provided by the Commando Helicopter Force. However, she can also support the Apache AH1 operated by the Army Air Corps and helicopters of the Royal Air Force including the Chinook.

Prior to their retirement, Ocean could transport up to 15 fixed wing Harrier aircraft of Joint Force Harrier in the ferry role, but was unable to operate as a fixed wing aircraft carrier due to her lack of the 'ski jump' that is needed to launch a fully loaded Harrier.

Landing craft

4 Mk5B LCVP are permanently embarked and manned by 9 Assault Squadron Royal Marines.
