The Durance class is a series of multi-product replenishment oilers, originally designed and built for service in the French Navy. Besides the five ships built for the French Navy, a sixth was built for the Royal Australian Navy, while the lead ship of the class currently serves with the Argentine Navy. Two ships of a similar but smaller design are in service with the Royal Saudi Navy as the Boraida-class replenishment oilers.
In French Navy service the ships were used with the Force d'action navale (FAN, "Naval Action Force"). The last three French ships were built to a modified design with increased space for command operations. The three ships are used as flagships for French naval forces in the Indian Ocean. In 2009, Somme repelled an attack by pirates off the coast of Somalia. The lead ship of the class (Durance) was transferred from France to Argentina in 1999/2000. In 2015, the second French ship was removed from service, followed by a third in 2021 and a fourth in 2023. In 2019, the Australian ship (HMAS Success) was also taken out of service.
In French service, the class the first two ships were dubbed Pétrolier Ravitailleur d'Escadre (PRE, "fleet replenishment oiler"), and the final three, Bâtiment de commandement et ravitailleur (BCR, "command and replenishment ship"). [1] In addition to their role as a fleet tanker, the three dubbed BCR can accommodate an entire general staff and thus supervise naval operations. [2] Meuse, which had a superstructure that was one deck higher than Durance, the lead ship of the class and the final three ships of the class, Var, Marne and Somme all had superstructures that were extended aft by 8 m (26 ft) to accommodate the additional staff requirements. The first two ships carry two cranes abaft the bridge, while the final three only have one positioned along the centreline. [3]
The five ships are of similar design but different layouts. Durance and Meuse had a standard displacement of 7,700 tonnes (7,600 long tons ) and 18,200 t (17,900 long tons) at full load. Marne, Var and Somme have a standard displacement of 7,900 t (7,800 long tons) and 18,800 t (18,500 long tons) at full load. All five ships are 157.3 metres (516 ft 1 in) long overall and 149 m (488 ft 10 in) between perpendiculars with a beam of 21.2 m (69 ft 7 in) and a draught of 8.65 m (28 ft 5 in) empty and 10.8 m (35 ft 5 in) at full load. All five vessels are powered by two SEMT Pielstick 16 PC2.5 V 400 diesel engines turning two LIPS controllable pitch propellers rated at 15,000 kilowatts (20,000 hp ). The vessels have a maximum speed of 19 knots (35 km/h; 22 mph) and a range of 9,000 nmi (17,000 km; 10,000 mi) at 15 knots (28 km/h; 17 mph). [1] [4]
Durance was initially equipped with two landing craft for vehicles and personnel. [5] Each ship has two dual solid/liquid underway transfer stations per side and can replenish two ships per side and one astern. [3] As built, Durance had capacity for 7,600 t (7,500 long tons) of fuel oil, 1,500 t (1,500 long tons) of diesel oil, 510 t (500 long tons) of JP-5 aviation fuel, 130 t (130 long tons) of distilled water, 170 t (170 long tons) of provisions, 150 t (150 long tons) of munitions and 51 t (50 long tons) of spare parts. Meuse had capacity for 5,170 t (5,090 long tons) of fuel oil, 4,078 t (4,014 long tons) of diesel, 1,160 t (1,140 long tons) of JP-5 aviation fuel, 250 t (250 long tons) of distilled water, 180 t (180 long tons) of provisions, 124 t (122 long tons) of munitions and 46 t (45 long tons) of spare parts. The final three ships of the class differed from Meuse by carrying 3,360 t (3,310 long tons) of diesel fuel, 1,160 t (1,140 long tons) of JP-5 aviation fuel, 170 t (170 long tons) of munitions and 15 t (15 long tons) of spare parts. [4] These numbers changed with the needs of the fleet. [1]
The Durance-class tankers all mount a flight deck over the stern and a hangar. The ships utilised Aérospatiale Alouette III and Westland Lynx helicopters (prior to the retirement of both types) but are capable of operating larger ones from their flight deck. For defence, Durance was armed with twin-mounted Bofors 40 mm (1.6 in)/L60 [a] anti-aircraft (AA) guns. The other four ships initially mounted one Bofors 40 mm/L60 AA guns and two 20 mm (0.8 in) AA guns in a twin turret. [4] They are equipped with two DRBN 34 navigational radars. The armament was later altered for the final four ships by removing the 20 mm guns and adding four 12.7 mm (0.5 in) M2 Browning machine guns and three launchers for Simbad Mistral surface-to-air missiles. Meuse had only one launcher installed. The ships have a complement of 162 and are capable of accommodating 250 personnel. [1]
Five ships of the class were built for the French Navy:

Three ships of the class (Marne, Somme, and Var) were fitted out as flagships able to embark an admiral and his staff. The 2013 French White Paper on Defence and National Security planned to replace them with four new double-hulled tankers between 2018 and 2021. [9] However, Meuse was decommissioned in December 2015, [10] under budget cuts announced a year earlier. [11] Var followed in 2021 and Marne in 2023. They will be replaced under the FLOTLOG project by four Bâtiment ravitailleur de forces vessels, with the first ship having been delivered in 2023 and the others to follow in 2025 and 2027, as well as a fourth projected after 2030. [12] [13] [14]
The first four tankers were constructed by the Arsenal de Brest at Brest, France between 1973 and 1987. [4] The fifth and final ship was ordered in March 1984 as part of the 1984–1988 plan and was built by Normed at their yard La Seyne, France. [1] [2] The Durance-class ships began entering service in 1976 were assigned to the Force d'action navale (FAR, "Naval Action Force"). Prior to 2010, one of the BCRs (Var, Marne or Somme) had been assigned to Indian Ocean as flagship of the French naval forces in the region. [1] In October 2009, Somme repelled an attack by Somali pirates. [15]
The Royal Australian Navy (RAN) ordered one vessel, HMAS Success, of a modified design in September 1979. A second vessel was planned in 1980, but not optioned. Construction of Success was slow and costs increased. [16] The modified Durance-class oiler is 157.2 m (515 ft 9 in) in length, with a beam of 21.2 m (69 ft 7 in), and a draught of 8.6 m (28 ft 3 in), with a full load displacement of 18,221 t (17,933 long tons). [17] Propulsion machinery consisted of two SEMT-Pielstick 16 PC2.5 V 400 diesel motors, which supplied 15,500 kW (20,800 hp) to the ship's two propeller shafts. Top speed was 20 knots (37 km/h; 23 mph), and the ship had a range of 8,616 nmi (15,957 km; 9,915 mi) at 15 knots (28 km/h; 17 mph). Success had a total capacity of 10,200 tonnes of cargo: 8,707 tonnes of diesel fuel, 975 tonnes of aviation fuel, 250 tonnes of munitions (including guided missiles and torpedoes), 116 tonnes of water, 95 tonnes of components and naval stores, and 57 tonnes of food and other consumables. [18] Fuel and liquid stores could be transferred from four points (two on each side), allowing Success to replenish two ships simultaneously, while solid cargo could be moved via vertical replenishment (with a hangar and helipad for a single Sea King, Seahawk, or Squirrel helicopter), or by boat (the RAN LCVP T 7 was carried on a starboard forward davit). [17] The ship was armed with seven 12.7 mm machine guns, and was fitted for but not with a Mark 15 Phalanx CIWS. The sensor suite includes two Kelvin Hughes Type 100G navigation radars. Ship's company was made up of 25 officers and 212 sailors. [18]

On 12 July 1999, Argentina acquired Durance from the French Navy (originally commissioned into French service in 1976) and renamed the ship ARA Patagonia. The ship underwent a refit and has capacity for 9,100 t (9,000 long tons) of fuel oil, 500 t of aviation fuel, 140 t of distilled water, 170 t of provisions, 150 t of munitions and 50 t of spare parts. The ship mounts only two Bofors 40 mm/60 guns and four 12.7 mm machine guns. The ship uses an Alouette III helicopter. The ship entered Argentine Navy service in July 2000. [21] The ship was reported non-operational in 2020. [22] In October 2022, it was reported that the Argentine defence ministry had allocated funding for a refit of the ship to be carried out at the Puerto Belgrano Naval Arsenal in collaboration with the Tandanor shipyard. [23] The ship was reported to have entered dry dock in early 2023. [24] Work on the ship, involving general maintenance and repair, was reported to have been completed in June 2023. [25]

In October 1980, Saudi Arabia signed a contract for two replenishment oilers as part of the Sawari I programme. The Boraida class have a full load displacement of 11,400 t (11,200 long tons), are 135 m (442 ft 11 in) long, have a beam of 18.7 m (61 ft 4 in), and a draught of 7 m (23 ft 0 in). They use two 18,200 horsepower (13,600 kW) SEMT Pielstick 14 PC2.5 V 500 diesel engines driving two shafts. They have a top speed of 20.5 knots (38.0 km/h; 23.6 mph) and a range of 7,000 nmi (13,000 km; 8,100 mi) at 15 knots. They have a complement of 140. The ship can carry 4,350 tonnes (4,280 long tons; 4,800 short tons) of diesel, 35 tonnes (34 long tons; 39 short tons) of aviation fuel, 140 tonnes (140 long tons; 150 short tons) of freshwater, 100 tonnes (98 long tons; 110 short tons) of ammo, and 100 tonnes (98 long tons; 110 short tons) of supplies. The ship is armed by four Breda Bofors 40 mm/70 guns in two twin mounts. They have two CSEE Naja optronic fire control directors for the 40 mm guns. They have an aft helicopter deck, and can carry either two Eurocopter AS365 Dauphin or one Eurocopter AS332 Super Puma helicopters. Both ships underwent upgrades in 1996–1998. They serve as training ships and depot and maintenance ships. [28]

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.
A replenishment oiler or replenishment tanker is a naval auxiliary ship with fuel tanks and dry cargo holds which can supply both fuel and dry stores during underway replenishment (UNREP) at sea. Many countries have used replenishment oilers.
The Foudre-class landing platform dock is a class of landing platform docks designed and constructed for the French Navy. Designated Transport de Chalands de Débarquement, they were intended to replace the ageing Ouragan class and the construction of four vessels was planned. Only two were built and the remaining two were instead reordered as Mistral-class amphibious assault ships. The two ships of the Foudre class, Foudre and Siroco, operated with the French Navy between 1990 and 2014. Replaced by the Mistrals, in 2011 Foudre was sold to the Chilean Navy and Siroco was sold to the Brazilian Navy in 2015.
The Almirante Padilla-class frigates is a series of frigates operated by the Colombian Navy. The designation of this class is Type FS 1500 and there are four ships in service. The ships were built by Howaldtswerke-Deutsche Werft (HDW) at Kiel, West Germany in the 1980s, with the first vessel commissioning in 1983 and the last in 1984. The frigates have undergone significant modification over their careers with the 2012 Orion Program Upgrade significantly modernising the vessels. Two similar ships operate as the Kasturi-class corvettes in the Royal Malaysian Navy.
Newport-class tank landing ships were an improved class of tank landing ship (LST) designed for and employed by the United States Navy from 1969 to 2002. The ships were intended to provide substantial advantages over their World War II-era predecessors. Larger and faster than any previous LST design, they carried a ramp over the bow that allowed them to surpass 20 knots, a goal of the United States amphibious forces. 27 were planned of which twenty were completed, the high number due to the demands of US force projection estimates. However, the arrival of the air-cushioned landing craft which allowed for over-the-horizon attacks made the class obsolete in the eyes of the United States Navy. Placed in reserve, twelve were eventually sold to foreign navies, while the remaining eight have since been decommissioned.
The Type 704 Rhön-class tankers are a series of replenishment oilers used by the German Navy to provide underway replenishment for its ships at sea. The two vessels in the class, Rhön and Spessart, were originally constructed for Libya by Kröger Shipyard in Rendsburg, West Germany as bulk acid carriers. They were acquired by the West German Navy in 1976 for conversion and entered service in 1977. The two ships are crewed by civilians. In 2019 it was announced by the German Navy that the ships are planned to be replaced in 2024.
ARA Patagonia (B-1) is a multi-product replenishment oiler of the Durance class in service in the Argentine Navy. She was the lead ship of her class serving in the French Navy as Durance from 1977 to 1999. In French service, the ship served with the Force d'action navale. In Argentine service the vessel is used in multi-national naval exercises and supplies the Antarctic missions operating from Ushuaia. In 2017, Patagonia was used to search for the missing submarine ARA San Juan.
The Chamsuri class are patrol boats originally constructed for and operated by the Republic of Korea Navy. They first entered service in 1979, and they have since seen service with five other navies, of which the Philippine Navy is currently the largest import user. These boats were built by the Korea Tacoma, and Korea SB & Eng. Masan shipyards. In Korea, the Chamsuri-class boats are being retired and replaced by Gumdoksuri-class patrol vessels.
The French tanker Somme is a Durance-class command and replenishment tanker of the French Navy. In addition to its primary duty as a fleet tanker, Somme is configured as a flagship and has served as such in the Indian Ocean. The vessel was constructed at La Seyne, France beginning in 1985 and entered service in 1990. As of 2023, with the retirement of her sister ship Marne, she is the last vessel of her class in service with the French Navy.
The Vulcano class is a class of replenishment oiler used by the Italian Navy, with lead ship Vulcano of the class entered service on 12 March 2021. The ships are designed to support fleet operations with fuel and dry stores and expected to replace the Stromboli class, another class of replenishment oiler from the Navy. Vulcano was financed under the 2014 Naval Law, for €346 million, then increased to €374.6 million, when the length was extended by 12 metres (39 ft). A second ship Atlante was ordered in January 2022 for projected delivery in 2025. The Navy also had an option for a third ship of the class. However, under the Italian MoD’s Multi-Year Defence Planning Document for the 2023-2025 timeframe, a fourth ship was added to the program.
The Boraida class is a ship class of two replenishment oilers built for the Royal Saudi Navy by CN la Ciotat at Marseille, France. It is a modified version of the French Durance-class replenishment ship. They were constructed in 1983 and entered service in 1984. The two ships are based at Jeddah, Saudi Arabia.
The Akar class is a series of two replenishment oilers and fleet support ships, designed and built for service in the Turkish Navy. The lead ship of the class, TCG Akar, was constructed in 1982–1983 and entered service in 1987. The second ship, TCG Yarbay Kudret Güngör, was constructed in 1993–1994 and entered service in 1995. Both ships were constructed in Turkey, though Yarbay Kudret Güngör was the first ship built for the Turkish Navy by a private shipyard. Both vessels remain in service.
ARA Punta Médanos (B-18) was an auxiliary ship of the Argentine Navy, a tanker built at the Swan, Hunter & Wigham Richardson shipyard, Wallsend, in 1950. While in naval service she made several commercial trips supplementing the YPF tanker fleet, and supported the high seas fleet; in this capacity Punta Médanos participated in the Falklands War in 1982. She was decommissioned in 1984 and sold for scrapping. The vessel was named after the coastal feature of Punta Médanos, Argentina, and was the first Argentine naval ship with this name.
ARA Bahía Paraíso was an Argentine Navy auxiliary ship that sank in 1989, 2 miles (3.2 km) from Palmer Station at Arthur Harbor, Antarctica, resulting in a 170,000 US gal oil spill.
The Chaland de transport de matériel (CTM) is a French landing craft class, also operated by the navies of Chile, Djibouti, Ivory Coast, Morocco and Senegal. The design is based on the American LCM-8-class landing craft and were initially ordered to support France's nuclear testing in the Pacific. Constructed in two batches, the first batch of 16 vessels have been removed from French service with some transferred to other navies, the others being discarded. The second batch consisting of 17 vessels is split, with some being transferred to other nations and some remaining in service with the French Navy. The remaining vessels in French service are being replaced with a new landing craft design. As of January 2023, it was reported that only five of the landing craft remained in French Navy service.
Frankfurt am Main (A1412) is the second ship of the Berlin-class replenishment ships of the German Navy. Ordered in 1997, the vessel was constructed in Hamburg by Flensburger Schiffbau-Gesellschaft and was launched on 5 January 2001. Frankfurt am Main was commissioned on 27 May 2002 and is currently in service.
Meuse is a Durance-class replenishment oiler of the French Navy. Constructed by the Brest Arsenal in Brest, France, the vessel was launched on 2 December 1978 and entered service in 1980. The tanker served on several overseas operations, often operating with France's aircraft carriers in a support role. Meuse was taken out of service on 16 December 2015.
Var was a Durance-class command and replenishment tanker of the French Navy. In addition to its primary duty as a fleet tanker, Var was configured as a flagship and served as such in the Indian Ocean. The ship was laid down on 8 May 1979 by Brest Arsenal at their yard in Brest, France. She was launched on 1 June 1981, commissioned on 29 January 1983 and assigned to the Force d'action navale. Var took part in several multi-national operations. The tanker was decommissioned on 1 July 2021.
Marne was a Durance-class command and replenishment tanker of the French Navy. In addition to its primary duty as a fleet tanker, Marne was configured as a flagship and served as such in the Indian Ocean.
The bâtiments ravitailleurs de forces, or BRF, are a class of future fleet tankers that are to replace the Durance-class units in French Navy service. Until January 2019, the programme was known as Flotte logistique. First ship of the class was delivered to the French Navy in July 2023 and formally entered service in November 2024. The ships are part of the Vulcano-class logistic support ship programme.
