The Tide class was a series of six replenishment oilers used by the British Royal Fleet Auxiliary (RFA), the Royal Australian Navy (RAN), and the Chilean Navy.
The class was based on RFA Olna, which had served with the British Pacific Fleet during World War II. Three ships were laid down for the RFA in 1953, with a fourth being ordered by the RAN at the same time. Two more ships, built for the RFA to a modified design, were launched in 1962.
Upon completion, the Australian Tide Austral could not be accepted into service because of manpower and financial difficulties. The ship was instead loaned to the RFA from 1955 until 1962, when she was returned to the RAN and commissioned as HMAS Supply. She was paid off in 1985.
The first three ships were removed from service and scrapped during the late 1970s. The two modified ships, Tidespring and Tidepool saw service in the Falklands War, after which Tidepool was sold to the Chilean Navy and renamed Almirante Jorge Montt.Tidespring remained with the RFA and was scrapped in 1992. Supply remained with the RAN until 1985.

The Royal Fleet Auxiliary (RFA) is a naval auxiliary fleet owned by the UK's Ministry of Defence. It provides vital logistical and operational support to the Royal Navy and Royal Marines. The RFA ensures the Royal Navy is supplied and supported by providing fuel and stores through replenishment at sea, transporting Royal Marines and British Army personnel, providing medical care and transporting equipment and essentials around the world. In addition the RFA acts independently providing humanitarian aid, counter piracy and counter narcotic patrols together with assisting the Royal Navy in preventing conflict and securing international trade. They are a uniformed civilian branch of the Royal Navy staffed by British merchant sailors.
HMAS Success was a Durance-class multi-product replenishment oiler that previously served in the Royal Australian Navy (RAN). Built by Cockatoo Docks & Engineering Company in Sydney, Australia, during the 1980s, she is the only ship of the class to be constructed outside France, and the only one to not originally serve in the Marine Nationale. The ship was part of the Australian contribution to the 1991 Gulf War, and was deployed to East Timor in response to incidents in 1999 and 2006. The ship was fitted with a double hull during the first half of 2011, to meet International Maritime Organization standards.
HMS Vengeance (R71) was a Colossus-class light aircraft carrier built for the Royal Navy during World War II. The carrier served in three navies during her career: the Royal Navy, the Royal Australian Navy, and the Brazilian Navy.
RFA Fort Rosalie was the lead ship of her class of Royal Fleet Auxiliary fleet replenishment ships. Fort Rosalie was originally named RFA Fort Grange, but was renamed in May 2000 to avoid confusion with the now-decommissioned RFA Fort George. On 31 March 2021, the ship was withdrawn from service.
RFA Tidespring (A75) was a Tide-class replenishment oiler of the Royal Fleet Auxiliary. As a replenishment oiler, her main purpose was to refuel other ships. The ship had a long career in the RFA, entering service in the early 1960s, and finally being decommissioned in 1991.
RFA Tidepool (A76) was a Tide-class replenishment oiler of the Royal Fleet Auxiliary.
HMAS Choules (L100) is a Bay-class landing ship that served with the Royal Fleet Auxiliary (RFA) from 2006 to 2011, before being purchased by the Royal Australian Navy (RAN). The vessel was built as RFA Largs Bay by Swan Hunter in Wallsend, Tyne and Wear. She was named after Largs Bay in Ayrshire, Scotland, and entered service in November 2006. During her career with the RFA, Largs Bay served as the British ship assigned to patrol the Falkland Islands in 2008, and delivered relief supplies following the 2010 Haiti earthquake.
HMAS Supply was a Tide-class replenishment oiler of the Royal Fleet Auxiliary (RFA) and the Royal Australian Navy (RAN). Originally named Tide Austral and intended to be the first ship of a post-World War II Royal Australian Fleet Auxiliary, manpower and financial shortages meant that when the Belfast-built ship was launched in 1955, she could not be accepted into Australian service. Instead, she was loaned to the RFA, operating RFA Tide Austral (A99). In August 1962, the ship was commissioned directly into the RAN, then renamed a month later to HMAS Supply. Supply operated as part of the RAN until her decommissioning at the end of 1985.
The Bay class is a ship class of four dock landing ships built for the British Royal Fleet Auxiliary (RFA) during the 2000s. They are based on the Dutch-Spanish Royal Schelde Enforcer design, and replaced the Round Table-class logistics ships. Two ships each were ordered from Swan Hunter and BAE Systems Naval Ships. Construction work started in 2002, but saw major delays and cost overruns, particularly at Swan Hunter's shipyard. In mid-2006, Swan Hunter was stripped of work, and the incomplete second ship was towed to BAE's shipyard for completion. All four ships, Largs Bay, Lyme Bay, Mounts Bay, and Cardigan Bay had entered service by 2007.
HMAS Anzac is the lead ship of the Anzac-class frigates in use with the Royal Australian Navy (RAN) and the Royal New Zealand Navy (RNZN). Entering Australian service in 1996, the frigate operated as part of the INTERFET peacekeeping taskforce in 1999. In 2003, she was involved in the Battle of Al Faw, and became the first RAN ship to fire in anger since the Vietnam War. The ship is operational as of 2021.
HMAS Westralia was a modified Leaf-class replenishment oiler which served with the Royal Australian Navy (RAN) from 1989 to 2006. Formerly RFA Appleleaf (A79), she served in with the British Royal Fleet Auxiliary (RFA) from 1975 to 1989. The ship was initially leased to the RAN, then purchased outright in 1994. In 1998, a fire onboard resulted in the deaths of four sailors. Westralia was decommissioned in 2006, and the ship was sold into civilian service for use as a Floating Production Storage and Offloading vessel, under the name Shiraz. However, the ship was laid up in Indonesia until late 2009, when she was sold to a Turkish ship breaking company. Arriving in January 2010, the vessel was scrapped.
HMAS Sirius was a commercial tanker purchased by the Royal Australian Navy and converted into a fleet replenishment vessel to replace HMAS Westralia. She was named in honour of HMS Sirius of the First Fleet. Launched in South Korea on 2004, and converted in Western Australia, Sirius was commissioned in 2006; three years before a purpose-built vessel would have been built, and at half the cost. The tanker was decommissioned in 2021.
The Fort Rosalie or Fort class of fleet replenishment vessel of the British Royal Fleet Auxiliary were designed to replenish Royal Navy taskgroups with various armaments and victualling stores while under way. Unlike the bigger Fort Victoria class, they supply dry stores and not fuel. RFA Fort Rosalie was originally known as Fort Grange but was renamed in 2000 to avoid confusion with the new Fort Victoria-class replenishment oiler RFA Fort George. Both ships were withdrawn from service and later sold in 2021.
The Tide-class tanker is a class of four fast fleet tankers that entered service with the British Royal Fleet Auxiliary from 2017. The 37,000 t ships provide fuel, food, fresh water, ammunition and other supplies to Royal Navy vessels around the world. Norway ordered a similar 26,000 t version with a 48-bed hospital and greater solid stores capacity, but reduced liquid capacity; it was delivered in November 2018 as HNoMS Maud two years after originally planned. The two classes are very similar, but are not directly comparable due to large variance in capabilities delivered.
RFA Tidespring is a Tide-class replenishment tanker of the British Royal Fleet Auxiliary (RFA). Built by DSME in 2016, the ship entered service with the Royal Fleet Auxiliary in November 2017.
RFA Tiderace is a Tide-class replenishment tanker of the British Royal Fleet Auxiliary (RFA). Ordered from DSME in 2012, she was officially named on 1 December 2016 and was accepted by the Ministry of Defence in June 2017. Tiderace entered service on 2 August 2018.
RFA Tidesurge is a Tide-class replenishment tanker of the British Royal Fleet Auxiliary (RFA). Built by DSME in 2017, she entered service with the RFA on 20 February 2019.
RFA Tideforce is a Tide-class replenishment tanker of the British Royal Fleet Auxiliary (RFA). Launched in 2017, the ship entered service with the RFA in 2019.
The Supply class is a class of replenishment oilers of the Royal Australian Navy, a role that combines the missions of a tanker and stores supply ship. As such they are designated auxiliary oiler replenisher (AOR). They are tasked with providing ammunition, fuel, food and other supplies to Royal Australian Navy vessels around the world. There are two ships in the class, Supply and Stalwart. The project is expected to cost anywhere between $1 and $2 billion. Navantia were selected to build a design based on the Spanish Navy's current replenishment vessel Cantabria, which entered service in 2011.
