An auxiliary ship is a naval ship designed to operate in support of combatant ships and other naval operations. Auxiliaries are not primary combatants, although they may have some limited combat capacity, usually of a self-defence nature.
Auxiliaries are extremely important for navies of all sizes, as without them, the primary fleet vessels cannot be effective. Thus, nearly every navy maintains an extensive fleet of auxiliaries. However, the composition and size of these auxiliary fleets varies 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. Larger blue-water navies tend to have large auxiliary fleets comprising longer-range fleet support vessels designed to provide support far beyond territorial waters.
The Aditya-class auxiliary ship is a class of replenishment and repair ships currently in service with the Indian Navy. The class is a modified and lengthened version of the original Deepak class. INS Aditya is the only ship in this class.Ammunition ship
An ammunition ship is an auxiliary ship specially configured to carry ammunition, usually for naval ships and aircraft. An ammunition ship′s cargo handling systems, designed with extreme safety in mind, include ammunition hoists with airlocks between decks, and mechanisms for flooding entire compartments with sea water in case of emergencies. Ammunition ships most often deliver their cargo to other ships using underway replenishment, using both connected replenishment and vertical replenishment. To a lesser extent, they transport ammunition from one shore-based weapons station to another.Armadillo-class tanker
The Armadillo class of tankers was a class of Type Z-ET1-S-C3 Liberty tankers that were commissioned into the United States Navy. They were given the hull classification symbols of unclassified miscellaneous vessels.
This group of Liberty based tankers all served in the United States Navy during the Second World War. Each ship was commissioned in late 1943, and decommissioned in the summer of 1946. These ships primarily served in the Asian-Pacific theater of the war. They brought aviation gasoline to remote islands in the south Pacific, required for the many reconnaissance missions.Crater-class cargo ship
Crater-class cargo ship is a category of EC2-S-C1 type liberty ship freighters constructed by the United States Maritime Commission for use by the U.S. Navy during World War II. The designation 'EC2-S-C1' was composed of 'EC' (for Emergency Cargo), '2' (for a ship between 400 and 450 feet (120 and 140 m) long (Load Waterline Length)), 'S' (for steam engines), and 'C1' for a Type C1 ship.
The class was named for the lead ship of its type, USS Crater (AK-70). Its 62 hulls was the largest among U.S. Navy cargo ship classes.
The ships were propelled by a reciprocating steam engine using a single screw with a power of 1,950 hp (1,454 kW) shaft.Crosley-class high speed transport
Crosley-class high speed transports were high speed transport ships that served in the United States Navy during World War II. Some stayed in commission long enough to serve in the Korean War and the Vietnam War. All of them were converted from Rudderow-class destroyer escorts during construction except for USS Bray (APD-139), which was converted a year after her construction. After World War II ended, several of the ships were sold to Mexico, South Korea, Taiwan, and Colombia.
Today, ARC Cordoba (DT-15), formerly USS Ruchamkin (APD-89) is the only surviving member of the class, preserved as a museum ship in Tocancipa, Colombia.Destroyer tender
A destroyer tender, or destroyer depot ship in British English, is an auxiliary ship designed to provide maintenance support to a flotilla of destroyers or other small warships. The use of this class has faded from its peak in the first half of the 20th century as the roles of small combatants have evolved (in conjunction with technological advances in propulsion reliability and efficiency).Fighter catapult ship
Fighter catapult ships also known as Catapult Armed Ships were an attempt by the Royal Navy to provide air cover at sea. Five ships were acquired and commissioned as Naval vessels early in the Second World War and these were used to accompany convoys.
The concept was extended to merchant ships which were also equipped with rocket assisted launch systems and known as Catapult Aircraft Merchantmen (CAM ships).Italian auxiliary ship Olterra
The auxiliary ship Olterra was a 5,000 ton Italian tanker scuttled by her own crew at Algeciras in the Bay of Gibraltar on 10 June 1940, after the entry of Italy in World War II. She was recovered in 1942 by a special unit of the Decima Flottiglia MAS to be used as an undercover base for manned torpedoes in order to attack Allied shipping at Gibraltar.List of Royal Fleet Auxiliary ship names
The following is a list of Royal Fleet Auxiliary ship names by name in alphabetical order, both past and present. Many of the names have been re-used over the years and thus represent more than one ship.List of auxiliary ship classes in service
The list of auxiliary ship classes in service includes all auxiliary ships in naval service in the world. For combatant ships, see the list of naval ship classes in service.Motor torpedo boat tender
Motor torpedo boat tender is a type of ship used by the U.S. Navy during World War II and Vietnam War. The motor torpedo boat tender's task was to act as a tender in remote areas for patrol boats (PT-boats) and to provide the necessary fuel and provisions for the torpedo boats she was responsible for. The type finds its root in the torpedo boat tender, developed in the 19th century.
This type of ship was classified as "AGP" and is sometimes called a "patrol craft tender."Natick-class tugboat
The Natick class is a class of harbor tugboats that have been active since the 1960s. Members of the class are named for Native American peoples and their members, USS Redwing excepted. As of 1 April 2015, five to eight Natick-class tugs remain in active service. Members of this class were designed to SCB-147A.Net laying ship
A net laying ship, also known as a net layer, net tender, gate ship or boom defence vessel was a type of small auxiliary ship.
A net layer's primary function was to lay and maintain steel anti-torpedo or anti-submarine nets. Nets could be laid around an individual ship at anchor, or around harbors or other anchorages. Net laying was potentially dangerous work, and net laying seamen were experts at dealing with blocks, tackles, knots and splicing. As World War II progressed, net layers were pressed into a variety of additional roles including salvage, troop and cargo transport, buoy maintenance, and service as tugboats.RFA Sir Geraint (L3027)
RFA Sir Geraint (L3027) was a Landing Ship Logistic of the Round Table class. She saw service in the Falklands War and Sierra Leone.RFA Tidespring (A75)
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.
Tidespring took part in the Falklands War, particularly in the recapture of South Georgia. At the time, she was carrying M Company (Captain Chris Nunn Royal Marines) of 42 Commando Royal Marines. The ship accommodated prisoners of war taken during operations. The Falklands provided a reprieve of ten years for Tidespring which had been due to decommission in 1982.
She eventually sailed from Portsmouth in tow on 20 March 1992 for the breakers, arriving in Alang, India for demolition on 2 July 1992.RMAS Goosander (A164)
RMAS Goosander (A164) was a mooring, salvage and boom vessel of the Royal Maritime Auxiliary Service. She saw service in the Falklands War. She has a sister ship, RMAS Pochard, and was built by Robb Caledon Shipbuilders in Leith.Repair ship
A repair ship is a naval auxiliary ship designed to provide maintenance support to warships. Repair ships provide similar services to destroyer, submarine and seaplane tenders or depot ships, but may offer a broader range of repair capability including equipment and personnel for repair of more significant machinery failures or battle damage.Type C3-class ship
Type C3-class ships were the third type of cargo ship designed by the United States Maritime Commission (MARCOM) in the late 1930s. As it had done with the Type C1 ships and Type C2 ships, MARCOM circulated preliminary plans for comment. The design presented was not specific to any service or trade route, but was a general purpose ship that could be modified for specific uses.
The C3 was larger and faster than the C1 and C2 contemporaries, measuring 492 feet (150 m) from stem to stern (vs. 459 feet (140 m) for the C2), and designed to make 16.5 knots (30.6 km/h; 19.0 mph) (vs. 15.5 kn (28.7 km/h; 17.8 mph) for the C2). Like the C2, it had five cargo holds. A total of 465 of these ships were built between 1940 and 1947.
During World War II, many C3 ships were converted to naval uses, particularly as Bogue-class escort carriers, and as Windsor-class and Bayfield-class attack transports, Klondike-class destroyer tenders, submarine tenders, and seaplane tenders.Valiant-class harbor tug
The Valiant class is a class of US Navy yard tugboats that entered service in 2009. These tugs are designed to provide ship assist, barge and general towing, and escort services.
