vessels are patrolling. There is always a Falkland Islands patrol vessel on deployment, currently . The Royal Navy operates a Response Force Task Group (a product of the 2010 Strategic Defence and Security Review), which is poised to respond globally to short-notice tasking across a range of defence activities, such as non-combatant evacuation operations, disaster relief, humanitarian aid or amphibious operations. In 2011, the first deployment of the task group occurred under the name 'COUGAR 11' which saw them transit through the Mediterranean where they took part in multinational amphibious exercises before moving further east through the Suez Canal for further exercises in the Indian Ocean. In the Persian Gulf, the RN sustains commitments in support of both national and coalition efforts to stabilise the region. The Armilla Patrol, which started in 1980, is the navy's primary commitment to the Gulf region. The Royal Navy also contributes to the combined maritime forces in the Gulf in support of coalition operations. The UK Maritime Component Commander, overseer of all of His Majesty's warships in the Persian Gulf and surrounding waters, is also deputy commander of the Combined Maritime Forces. The Royal Navy has been responsible for training the fledgeling Iraqi Navy and securing Iraq's oil terminals following the cessation of hostilities in the country. The Iraqi Training and Advisory Mission (Navy) (Umm Qasr), headed by a Royal Navy captain, has been responsible for the former duty whilst Commander Task Force Iraqi Maritime, a Royal Navy commodore, has been responsible for the latter. The Royal Navy contributes to standing NATO formations and maintains forces as part of the NATO Response Force.

This deployment typically consists of a frigate and a survey vessel, operating separately. Operation Atalanta, the European Union's anti-piracy operation in the Indian Ocean, is permanently commanded by a senior Royal Navy or Royal Marines officer at Northwood Headquarters and the navy contributes ships to the operation. From 2015, the Royal Navy also re-formed its UK Carrier Strike Group (UKCSG) after it was disbanded in 2011 due to the retirement of HMS Ark Royal and Harrier GR9s. The Queen Elizabeth-class aircraft carriers form the central part of this formation, supported by various escorts and support ships, with the aim to facilitate carrier-enabled power projection.
