RFA Green Rover (A268) was a Rover-class fleet support tanker of the Royal Fleet Auxiliary, built by Swan Hunter Shipbuilders on the River Tyne, UK and completed in 1969. After decommissioning in 1992 she was sold to the Indonesian Navy and renamed KRI Arun (903)
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.
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 T2 tanker, or T2, was a class of oil tanker constructed and produced in large quantities in the United States during World War II. Only the T3 tankers were larger "navy oilers" of the period. Some 533 T2s were built between 1940 and the end of 1945. They were used to transport fuel oil, diesel fuel, gasoline and sometimes black oil-crude oil. Post war many T2s remained in use; like other hastily built World War II ships pressed into peacetime service, there were safety concerns. As was found during the war, the United States Coast Guard Marine Board of Investigation in 1952 stated that in cold weather the ships were prone to metal fatigue cracking, so were "belted" with steel straps. This occurred after two T2s, Pendleton and Fort Mercer, split in two off Cape Cod within hours of each other. Engineering inquiries into the problem suggested the cause was poor welding techniques. It was found the steel was not well suited for the new wartime welding construction. The high sulfur content made the steel brittle and prone to metal fatigue at lower temperatures.
The Cimarron-class oilers were an underway replenishment class of oil tankers which were first built in 1939 as "National Defense Tankers," United States Maritime Commission Type T3-S2-A1, designed "to conform to the approved characteristics for naval auxiliaries in speed, radius and structural strength", anticipating their militarization in the event of war. "Tentative plans had been reached with the Standard Oil Company of New Jersey to build ten high-speed tankers with the government paying the cost of the larger engines needed for increased speed. By the first week in December [1937], Standard Oil had solicited and received bids from a number of yards providing for the construction of a number of 16,300-ton (deadweight) capacity tankers. Bids were requested for two versions: a single-screw design of 13 knots and a twin-screw design of 18 knots. The price difference between the two would be used to establish the government's cost subsidy for greater speed. Plans and specifications for both designs were prepared for Standard Oil by naval architect E. L. Stewart. It seems certain that the design for the 18-knot tanker evolved out of the bureau's (C&R) design for a fleet oiler."
The Dale class were a class of replenishment oilers taken up for service with the Royal Fleet Auxiliary, supporting the Royal Navy during the inter-war period. They went on to see action during the Second World War and supported British and allied fleet units in Cold War conflicts such as the Korean War.
The Suamico class were a class of 25 United States Navy oilers during World War II. Built to the Maritime Commission T2-SE-A1, -A2 and -A3 (Cohocton) designs, they used turbo-electric transmission, obviating the need for reduction gearing which was a major issue in US mass-production shipbuilding.
The T3 tanker, or T3, are a class of sea worthy large tanker ships produced in the United States and used to transport fuel oil, gasoline or diesel before and during World War II, the Korean War and the Vietnam War. The T3 tanker classification is still used today. The T3 tanker has a full load displacement of about 24,830 tons.
The Eddy-class coastal tankers were Royal Fleet Auxiliary Replenishment oilers built from 1951–1953 tasked with transporting and providing fuel and other liquids to Royal Navy vessels and stations around the world. There were originally ten ships planned in the class, although the final two were cancelled in 1952. Originally designed to act as fleet attendant oilers, in this role the ships were obsolete almost as soon as they were built due to the increasing prevalence of replenishment at sea, and their role was refocused to coastal transport duties.
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 has ordered a 26,000 t version with a 48-bed hospital and greater solid stores capacity, for delivery in October 2016 as HNoMS Maud.
Type 626 tanker is a type of naval auxiliary ship currently in service with the People's Republic of China Navy (PLAN). Designed as a type that is capable of transport both water and oil, these ships entered service between 1964 – 1970. Type 626 tanker has received NATO reporting name as Fuzhou class, after the Chinese city Fuzhou. After transferred to reserves, these ships begun to retire in the early 2010s.
Type 620 tanker is a type of naval auxiliary ship currently in service with the People's Republic of China Navy (PLAN). Originally designed as a type that is capable of transport both water and oil, these ships entered service from 1981 onward for both military and civilian, but only the oiler version entered service with PLAN. Type 620 tanker has received NATO reporting name as Shengli class, meaning victory in Chinese. After transferred into reserves, these ships finally begun to retire in the early 2010s.
The Jinyou class oil tanker is a class of Chinese tanker that is in service with People's Liberation Army Navy (PLAN). A total of three units were built by Japanese Kanashashi Shipyard and entered service with PLAN between 1989 – 1990. These unarmed tankers were upgraded with Chinese radars after delivery, but remain unarmed. Specification:
Type 631 tanker is a type of naval auxiliary ship currently in service with the People's Liberation Army Navy (PLAN). Originally designed as a type that is capable of transport both water and oil, but only the oiler version entered service with PLAN.
Type 645 tanker is a type of naval auxiliary ship currently in service with the People's Liberation Army Navy (PLAN), and this type has received NATO reporting name as Guangzhou class. Originally designed as a coastal oiler that is capable of transport both water and oil, around twenty-three entered service, with four as water tankers and sixteen as oilers. This class has begun to be retired from active military service in the mid-2010s.
Beiyou 572 class oil tanker is a class of naval auxiliary ship currently in service with the People's Liberation Army Navy (PLAN).

The T1 tanker or T1 are a class of sea worthy small tanker ships used to transport fuel oil before and during World War II, Korean War and Vietnam War. The T1 tanker classification is still in use today. T1 tankers are about 200 to 250 feet in length and are able to sustain a top speed of about 12 knots. The hull designation AO is used by the US Navy to denote the ship is a T1 oil tanker and AOG that the T1 is a gasoline tanker. The small size allows the T1 to enter just about any sea port or to anchor around a small island, this was very useful during the Pacific War. The T1 tanker can carry about 48,000 to 280,000 BBLs. Some T1 tankers were used to transport goods other than oil, a few were used for black oil-crude oil, diesel, chemicals and rarely bulk cargo like grain. T1 tankers are also called liquid cargo carriers. The T1 tanker has about a 6,000 to 35,000 DWT of cargo. The small size also gives the ships short turn around time for repair, cleaning, loading and unloading. A T1 tanker carrying dirty cargo, like crude oil needs a few weeks of labor to clean before carrying clean cargo. Most T1 ships during World War II were named after major oil fields. T1 tanker are operated by the US Navy, War Shipping Administration and United States Maritime Commission. Some T1 were loaned to England in the Lend-Lease program for World War II, after the war most were returned to the USA. After World War II many of the T1 ships were sold to for civilian use. Each T1 had emergency life rafts on the boat deck. The ships had cargo booms and piping to load and unload fuel. During war time the T1 are armed for protection with deck guns. A typical ship may have one single 3"/50 dual purpose gun, two 40 mm guns and three single Oerlikon 20 mm cannon. A T1 at war time normally had a crew of 38 and up to 130. If operating as a United States Merchant Marine ship, the crew would be a mix of civilian Merchant Marines and United States Navy Armed Guards to man the guns.
