An auxiliary ship is a naval ship designed to support combatant ships and other naval operations. Auxiliary ships are not primary combatant vessels, though they may have some limited combat capacity, usually for purposes of self-defense.

#1732772621529288-410: Is indicated as either currently active [A], ready reserve [R], inactive [I], or precommissioning [P]. Ships in the inactive category include only ships in the inactive reserve, ships which have been disposed from US service have no listed status. Ships in the precommissioning category include ships under construction or on order. Listed ship classes will often state 'MA type' or 'MC type'. The difference
312-739: Is that 'MC Type' refers to ships designed by the United States Maritime Commission aka MarCom, while 'MA Type' refers to ships designed or converted under MarCom's successor agency, the United States Maritime Administration or MarAd. They are in fact the same designs, and the year 1950 is the date at which MarAd succeeded MarCom. Prior to the creation of the auxiliary hull classification system, ships that performed such tasks had no symbol or code to identify them, only informal designations such as Fleet Collier No. 1 . During World War I
336-557: The Navy created the Section patrol (SP) and identification number (ID) system to register civilian vessels for naval acquisition. The ID series can be considered a forerunner of the current auxiliary hull numbering system, and some ships with ID numbers were later given 'A' hull symbols. Also during WWI a series of mass-produced ships were designed by the Emergency Fleet Corporation , but few were completed before
360-407: The auxiliary series (which all begin with an 'A'). Links to these and other list articles of similar ships can be found throughout this article. Yard and district craft also function as auxiliaries but generally are smaller and less capable than their ocean-going counterparts, and so they generally remain in harbors and coastal areas. Their hull classification symbols begin with a 'Y'. Ship status

408-487: The end of the war and even fewer became naval auxiliaries . Until World War II the US auxiliary fleet was notable for being composed of non-standard ships which had been purchased ad-hoc . Very few were designed specifically for their intended role. Interesting examples from the 1920's of rare early auxiliaries deliberately designed for their roles include the destroyer tenders USS Dobbin (AD-3) and USS Whitney (AD-4) ,
432-892: The fleet, while the earlier Colliers supplied coal-burning steamships . Specific role replenishment vessels include combat stores ships , depot ships , general stores issue ships , and ammunition ships . Tenders are specifically designed to support a type of smaller naval unit, like submarines , destroyers , and seaplanes , providing a mobile base of operations for these units: specifically destroyer tenders , submarine tenders , seaplane tenders , torpedo boat tenders . Supporting front-line operating bases requires immense transportation capacity. Transport ships are often converted merchant ships simply commissioned (APA, APD, APH, APV) into naval service. Tankers are transports specifically designed to ship fuel to forward locations. Transport ships are often employed not only carrying cargo for naval support but are in support of all forces of
456-1878: The introduction of manning non-commissioned ships with civilian crews under the Military Sealift Command and its predecessors - such ships carry the 'T-' prefix on their hull symbols and the USNS prefix rather than USS; ships with MV or SS prefixes are under long-term charter with the Navy rather than under Navy ownership). unknown class: MA type C6-S-MA1qd Gopher State -class : MA type C5-S-73b unknown class: MA type C6-S-1aq unknown class: MA type C6-S-MA60d The Auxiliary aircraft carriers (ACV) were designated as Auxiliary aircraft escort vessels (AVG) until 20 August 1942 and then were redesignated Escort aircraft carriers (CVE) on 15 July 1943.

480-442: The most direct ways that auxiliary ships support the fleet is by providing underway replenishment (also known as "replenishment at sea") to major fleet units. This allows the fleet to remain in the same location, with the replenishment vessels bringing up fuel, ammunition , food, and supplies from shore to the fleet wherever it is operating. Oilers ("replenishment tankers") are vessels specifically designed to bring fuel oil to

#1732772621529528-520: The open sea, also disabled ships. Repairing ships at sea or in conflict areas is important as it allows these vessels to return to service more quickly, while also increasing the chance of survival for ships critically damaged in battle. Repair vessels (US Navy: AR, ARB, ARC, ARG, ARH, ARL, ARV) range from small equipment ships known as Auxiliary repair docks , to the larger Auxiliary floating drydocks , there are also Aircraft repair ships that specialize in repair of naval aircraft . Harbor support
552-560: The primary fleet vessels would be unsupported. Thus, virtually every navy maintains an extensive fleet of auxiliary ships, however, the composition and size of these auxiliary fleets vary 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, while larger blue-water navies tend to have larger auxiliary fleets comprising longer-range fleet support vessels designed to provide support far beyond territorial waters . One of
576-417: The repair ship USS Medusa (AR-1) , and the submarine tender USS Holland (AS-3) : these 4 ships had the same length hulls and similar superstructures, so they were likely of the same basic design.
