The fast combat support ship is a type of replenishment auxiliary ship. Different from traditional logistic ships, the fast combat support ship is designed with high speed to keep up with the carrier battle group/carrier strike group, while the multi-product station is capable of supplying all types of necessities for the fleet.
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 Henry J. Kaiser class is an American class of eighteen fleet replenishment oilers which began construction in August 1984. The class comprises fifteen oilers which are operated by Military Sealift Command to provide underway replenishment of fuel to United States Navy combat ships and jet fuel for aircraft aboard aircraft carriers at sea.
The T2 tanker, or T2, was a class of oil tanker constructed and produced in large numbers 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. Pendleton's sinking is memorialized in the 2016 film The Finest Hours. 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.
Underway replenishment (UNREP) or replenishment at sea (RAS) is a method of transferring fuel, munitions, and stores from one ship to another while under way. First developed in the early 20th century, it was used extensively by the United States Navy as a logistics support technique in the Pacific theatre of World War II, permitting U.S. carrier task forces to remain at sea indefinitely.
The Mars-class combat stores ships were a class of seven auxiliary vessels of the United States Navy. The ships were designed for underway replenishment, in support of carrier task force groups, carrying miscellaneous stores and munitions. Initially they carried no fuel oil or liquid cargo, but by the early 1990s the class was refitted with limited refuel capacities for F-76 fuel. None of the original seven ships originally commissioned by the US Navy remain in service. The Mars class was replaced by the Lewis and Clark-class dry cargo ships.
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."

A green-water navy is a maritime force that is capable of operating in its nation's littoral zones and has limited competency to operate in the surrounding marginal seas. It is a relatively new term, and has been created to better distinguish, and add nuance, between two long-standing descriptors: blue-water navy and brown-water navy.
USNS Tippecanoe (T-AO-199) is a Henry J. Kaiser-class underway replenishment oiler operated by the Military Sealift Command (MSC) to support ships of the United States Navy. She serves in the United States Pacific Fleet. Tippecanoe, the thirteenth ship of the Henry J. Kaiser class, was laid down at Avondale Shipyard, Inc., at New Orleans, Louisiana, on 19 November 1990 and launched on 16 May 1992. She entered non-commissioned U.S. Navy service under the control of the MSC with a primarily civilian crew on 8 February 1993.

The T3 tanker, or T3, are a class of seaworthy 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 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 deadweight tonnage (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.
