UK Carrier Strike Group
The UK Carrier Strike Group (UKCSG) is a carrier battle group of the Royal Navy. It has existed in various forms since the mid-2000s. Between 2006 and 2011, the formation centred around the Royal Navy's s until the retirement of their Harrier GR9 strike aircraft in 2011 as a result of the Strategic Defence and Security Review. The UKCSG subsequently returned in February 2015 ahead of the entry into service of the new s, and . The aim of the CSG is to facilitate carrier-enabled power projection. Overview. As a unit within the Royal Navy , the UK Carrier Strike Group's role is to facilitate carrier-enabled power projection (CEPP) in support of the UK's interests. As a self-contained force, it is capable of operating independently or as part of a wider operation. The unit is centred around either of two "Queen Elizabeth"-class aircraft carriers, which are designed to carry up to 40 aircraft each, with accompanying surface ships and submarines providing protection from air, surface and undersea threats. Whilst the Royal Navy has two aircraft carriers, the Royal Navy only plans to maintain one carrier strike group at a time. Size and  composition. The size and composition of the UKCSG varies depending on operational requirements which are decided upon during operational planning. A typical CSG consists of a "Queen Elizabeth"-class aircraft carrier, two surface escorts (with one being a Type 23 frigate for anti-submarine warfare and the other being a Type 45 destroyer for anti-air warfare), a submarine and a fleet tanker. In the future, escort duties will also be provided by the Royal Navy's new Type 26 frigate. For replenishment-at-sea, the Royal Fleet Auxiliary provides its Tide-class fleet tankers, which were specifically designed to refuel  the aircraft carriers, in addition to RFA "Fort Victoria" for dry stores. Currently, "Fort Victoria" is the only ship capable of resupplying the aircraft carriers with dry stores, however a programme to replace her with three new solid support ships is currently underway. Additionally, escorts and support ships may be provided by allies. Overseas, the UK has established a number of naval facilities to support the UKCSG, including the naval base HMS "Jufair" and the UK Joint Logistics Support Base, which are located in Bahrain and Oman, respectively. The "Queen Elizabeth"-class aircraft carriers are designed to carry around 40 aircraft  but can carry up to 72 at maximum capacity. Its Carrier Air Wing (CVW) will consist of up to 24 F-35B Lightning II multirole fighters by 2023. This is in addition to around 14 helicopters of varying types. For a Maritime Force Protection tasking, the CVW may consist of nine Merlin HM2 anti-submarine warfare helicopters and five Merlin HM2 Crowsnest for airborne early warning (AEW). Alternatively, for a Littoral Manoeuvre package, it may consist of a mixture of Chinook and Merlin Mk3i/4 transport helicopters and Apache AH1 and Wildcat AH1 attack helicopters. By 2030, the Royal Navy aims to  replace some of these helicopter platforms with medium-sized fixed wing unmanned aerial vehicles, currently known as Vixens, capable of undertaking strike, air-to-air refueling, electronic warfare and airborne early warning missions. Operational history. 2006–2011. The earliest iteration of the UK Carrier Strike Group originally formed in 2006 with Commodore Alan Richards in command. It centred around either of two s, and . In one of its final deployments, it demonstrated its capabilities alongside the U.S. Navy off the east coast of the United States during Exercise Auriga in 2010. Following the exercise, the captain of "Ark Royal" remarked: "Today  was a great opportunity for us to demonstrate some of the capabilities that the UK Carrier Strike Group has, particularly the GR9 Harrier and Merlin ASW helicopters operating from HMS Ark Royal". As an example of the size and composition of a UK CSG of that era, the Auriga CSG consisted of the aircraft carrier HMS "Ark Royal", along with her air wing of Harrier GR9 strike aircraft, Merlin HM1 anti-submarine warfare (ASW) helicopters and Sea King MK7 airborne surveillance and control (ASaC) helicopters. The aircraft carrier was escorted by the Type 42 destroyer and Type 23 frigate , in  addition to French Navy submarine "Perle" and U.S. Navy destroyer . of the Royal Fleet Auxiliary provided replenishment. In 2010, the British government announced that all Harriers would be retired from service, along with HMS "Ark Royal". This left "Illustrious" serving in a helicopter carrier role whilst replacement aircraft carriers and their associated air wings were procured. The UK Carrier Strike Group dissolved in 2011 with Commodore Simon J. Ancona as its final commander. "Illustrious" later went on to decommission in 2014, three years ahead of her replacement. 2015–present. In 2015, the UKCSG was re-formed with Commodore Jerry Kyd  as its commander. Under his direction, the UK CSG battle staff grew to include 22 core one-star battle staff by 2016. Kyd was later succeeded by Commodore Andrew Betton during the same year, who himself was succeeded in 2018 by Commodore Mike Utley, before the current commander, Commodore Stephan Moorhouse, took command in 2019. Prior to the entry into service of HMS "Queen Elizabeth" and her sister ship "Prince of Wales", the Royal Navy cooperated with its allies to preserve and develop its skills in carrier strike group operations. This primarily involved Royal Navy ships and personnel training with  U.S. Navy and French carrier strike groups. The current UKCSG assembled at sea for the first time in October 2020 during Exercise Joint Warrior. It comprised a total of nine ships, 15 fighter aircraft (five from the Royal Air Force and 10 from the U.S. Marine Corps), 11 helicopters and 3,000 personnel. The Royal Navy ships included the aircraft carrier HMS "Queen Elizabeth" along with two frigates, two destroyers, a replenishment ship and a solid support ship. The U.S. Navy and Royal Netherlands Navy also provided an escort each. The exercise saw the largest number of aircraft on a British  aircraft carrier since 1983, in addition to the largest number of F-35B’s at sea across the globe. The exercise was a rehearsal for an operational deployment scheduled for 2021, known as CSG21. Following Exercise Joint Warrior, the UK CSG reached its initial operating capability (IOC) milestone in January 2021. This milestone marked the successful operation of all components of the CSG and made it available for operational deployments for the first time. Carrier Strike Group 21. On 22 May 2021, following a farewell visit from Queen Elizabeth II, the UK Carrier Strike Group left HMNB Portsmouth on its first  operational deployment, a seven-and-a-half month roundtrip to the Pacific, visiting over 40 countries. Joining lead ship HMS "Queen Elizabeth" were Type 45 destroyers and , Type 23 frigates and , "Astute"-class nuclear attack submarine and two Royal Fleet Auxiliary supply ships, and . United States Navy destroyer and of the Royal Netherlands Navy were also assigned to the strike group. In total, approximately 3,700 sailors, aviators and marines from across the three countries were involved with the deployment. The strike group's air component amounted to over 30 aircraft, the majority of which were onboard HMS "Queen Elizabeth". These included  eight F-35B Lightning multirole combat aircraft from No. 617 Squadron RAF and ten from the United States Marine Corps' VMFA-211 "Wake Island Avengers". Three Merlin HM2 Crowsnest airborne surveillance and control (ASaC) aircraft were also deployed on the type's first operational deployment. Whilst in the Mediterranean, the carrier strike group exercised with the Italian Navy and Air Force, the and its accompanying strike group, as well as other NATO navies during Exercise Steadfast Defender. The strike group also carried out its first ever combat operations, launching F-35B Lightning multirole combat aircraft on strike sorties against Islamic State in Iraq  and Syria. Whilst these missions were underway, HMS "Defender" and HNLMS "Evertsen" detached from the strike group and headed into the Black Sea to carry out Freedom of Navigation Operations (FONOPs). Whilst transiting from Odessa, Ukraine to Batumi, Georgia, HMS "Defender" entered the waters around Crimea, the centre of a Russian-Ukrainian sovereignty dispute, which resulted in the Russian authorities firing warning shots. Elsewhere in the Black Sea, HNLMS "Evertsen" also faced mock attacks by the Russian Air Force. To further monitor the strike group, Russia deployed strike bombers equipped with Kh-47M2 Kinzhal anti-ship ballistic missiles to an airbase  in Syria. By 7 July 2021, both HMS "Defender" and HNLMS "Evertsen" had rejoined the strike group and it left the region via the Suez Canal. HMS "Diamond" was no longer part of the strike group, having suffered a defect. In the Gulf of Aden, the carrier strike group met with two U.S. Navy task groups, Carrier Strike Group 5 headed by and 's Amphibious Ready Group. The carrier strike group then exercised with the Indian Navy in the Bay of Bengal before exercising with the navies of Singapore, Malaysia and Thailand in the Strait of Malacca. Carrier Strike Group  22. The UK CSG is scheduled to deploy in 2022 with both aircraft carriers involved, as well as other ships alongside NATO and allied partners.
