These vessels also help maintain the harbor by dredging channels, maintaining jetties and buoys , and even providing floating platforms for port defenses. In US Navy, tugboats are type YT, YTB, YTM, YTL or
705-531: Is a unique support ship in the RFA and has served in various aviation support roles. On active operations, she can deploy as a Primary Casualty Receiving Ship (PCRS); essentially a hospital ship . She cannot be described as such – and was not afforded such protection under the Geneva Convention – as she is armed. Argus completed a refit in May 2007 intended to extend her operational life to 2020. Prior to

Rank insignia
846-736: Is the collective category for all specialist working uniforms. They are worn as required for duties. As of 2022–23, the RFA was reported to be facing considerable recruiting challenges. Manpower was said to have dropped by 5 per cent from 2021 to 2022, contributing to the reduced availability, and even potential redundancy, of some vessels. In September 2024 RFA sailors began strike action over low pay. Due to compounding personnel shortages, even routine ship movements were curtailed. The RFA recruits ratings either directly from industry (or where they are suitably trained to allow direct entry), or as apprentices whilst undertaking training. Officers are recruited in one of three ways: All new officers take part in

The RFA counts an aviation support vessel and dock landing ships amongst its assets. As of late 2024, the RFA was suffering from severe manpower shortages resulting in only 6 of 13 vessels being able to be crewed on a regular basis. The RFA was established in 1905 to provide logistical support for
1081-529: The Royal Naval Reserve and Sponsored Reserves . Although RFA personnel wear Merchant Navy rank insignia with naval uniforms, they are part of the Royal Navy. RFA vessels are commanded and crewed by these sailors, augmented with regular and reserve Royal Navy personnel who perform specialised functions such as operating and maintaining helicopters or providing hospital facilities. Royal Navy personnel are also needed to operate certain weapons, such as

1175-457: The 2021 defence white paper. The RFA has acquired a Multi-Role Ocean Surveillance Ship to protect undersea critical national infrastructure , such as gas pipelines and undersea cables. In February 2023, the vessel identified for this role - MV Topaz Tangaroa - was acquired and in October 2023 entered service as RFA Proteus . She was purchased for some £70 million and was converted to act as
1222-514: The Bay-class ships, and other vessels, starting in the 2030s. In the interim, the white paper had proposed to upgrade one of the Bay-class vessels with permanent hangar facilities in order to carry out the littoral strike role. However, in July 2022 it was reported that the future littoral strike role would in fact be assumed by RFA Argus after a refit to convert her to this role. Argus
1269-681: The Navy was involved in. The RFA performed important service to the Far East Fleet off Korea from 1950 until 1953, when sustained carrier operations were again mounted in Pacific waters. During the extended operations of the Konfrontasi in the 1960s, the RFA was also heavily involved. As the network of British bases overseas shrank during the end of the Empire, the Navy increasingly relied on
1316-551: The Navy. Since the Royal Navy of that era possessed the largest network of bases around the world of any fleet, the RFA at first took a relatively minor role. The RFA first became heavily relied upon by the Royal Navy during World War II , when the British fleet was often far from available bases, either due to the enemy capturing such bases, or, in the Pacific, because of the sheer distances involved. World War II also saw naval ships staying at sea for much longer periods than had been
1363-421: The RFA have meant that the capacity to do this had eroded (in 2024-25, for example, RFA Cardigan Bay which was normally assigned to the mine countermeasures support role was unavailable since she was in the U.K. for refit). The 2021 defence white paper proposed the acquisition of a new class of up to six Multi-Role Support Ships (MRSS) to support littoral strike operations . These vessels are to replace
1410-744: The RFA to supply its ships during routine deployments. The RFA played an important role in the largest naval war since 1945, the Falklands War in 1982 (where one vessel was lost and another badly damaged), and also the Gulf War , Kosovo War , Afghanistan Campaign and the 2003 invasion of Iraq . In July 2008, the RFA was presented with a Queen's Colour , an honour unique to a civilian organisation.

1504-408: The case since the days of sail. Techniques of replenishment at sea (RAS) were developed. The auxiliary fleet comprised a diverse collection, with not only RFA ships, but also commissioned warships and merchantmen as well. The need for the fleet to be maintained was unambiguously demonstrated by World War II. After 1945, the RFA became the Royal Navy's main source of support in the many conflicts that

Specific role replenishment vessels include combat stores ships , depot ships , general stores issue ships , and ammunition ships . Tenders are specifically designed to support a type of smaller naval unit, like submarines , destroyers , and seaplanes , providing a mobile base of operations for these units: specifically destroyer tenders , submarine tenders , seaplane tenders , torpedo boat tenders . Supporting front-line operating bases requires immense transportation capacity. Transport ships are often converted merchant ships simply commissioned (APA, APD, APH, APV) into naval service. Tankers are transports specifically designed to ship fuel to forward locations. Transport ships are often employed not only carrying cargo for naval support but are in support of all forces of
1739-667: The merchant navy vessels under charter to the Ministry of Defence performing sealift and fuel provisioning roles. The most important role provided by the RFA is replenishment at sea (RAS), therefore the mainstay of the current RFA fleet are the replenishment ships. Three classes of vessel are in service as of 2024: Fort Victoria , the Tide class and the Wave class . The Wave class are called ' Fleet Tankers ', which primarily provide under way refuelling to Royal Navy ships, but can also provide
1786-442: The most direct ways that auxiliary ships support the fleet is by providing underway replenishment (also known as "replenishment at sea") to major fleet units. This allows the fleet to remain in the same location, with the replenishment vessels bringing up fuel, ammunition , food, and supplies from shore to the fleet wherever it is operating. Oilers ("replenishment tankers") are vessels specifically designed to bring fuel oil to

The Point-class sealift ships were acquired in 2002 under a £1.25bn private finance initiative with Foreland Shipping known as the Strategic Sealift Service. These ships are Merchant Navy vessels leased to the Ministry of Defence (MoD) as and when needed and as such are not part of the RFA. However, they are listed here due to their role in expeditionary military operations and in provisioning U.K. military bases and facilities. Originally six ships were part of
1880-520: The open sea, also disabled ships. Repairing ships at sea or in conflict areas is important as it allows these vessels to return to service more quickly, while also increasing the chance of survival for ships critically damaged in battle. Repair vessels (US Navy: AR, ARB, ARC, ARG, ARH, ARL, ARV) range from small equipment ships known as Auxiliary repair docks , to the larger Auxiliary floating drydocks , there are also Aircraft repair ships that specialize in repair of naval aircraft . Harbor support
1927-560: The primary fleet vessels would be unsupported. Thus, virtually every navy maintains an extensive fleet of auxiliary ships, however, the composition and size of these auxiliary fleets vary depending on the nature of each navy and its primary mission. Smaller coastal navies tend to have smaller auxiliary vessels focusing primarily on littoral and training support roles, while larger blue-water navies tend to have larger auxiliary fleets comprising longer-range fleet support vessels designed to provide support far beyond territorial waters .

2162-735: Was purchased for £40 million and arrived at HMNB Devonport in January 2023. Her conversion was not anticipated to be lengthy. Full service entry took place in April 2024. Up to three additional ships are also planned for eventual acquisition in the mine countermeasures command and support role, one of which is intended to replace RFA Cardigan Bay and some of the other vessels in 9 Mine Countermeasures Squadron operating from HMS Jufair in Bahrain. The new vessels may either be conversions of existing commercial vessels or, as reportedly preferred by

A class of three new fleet solid support ships are expected to arrive starting in 2031 under the Fleet Solid Support Ship Programme . The manufacturing contract for this acquisition, valued at £1.6 billion, was signed in January 2023. The Tide class and Fort Victoria incorporate aviation facilities, providing aviation support and training facilities as well as vertical replenishment capabilities. They are capable of operating and supporting Merlin and Lynx Wildcat helicopters, both of which are significant weapons platforms. The presence of aviation facilities on RFA ships allows for them to be used as 'force multipliers' for
