This is a list of auxiliaries of the United States Navy. It covers the various types of ships that support the frontline combat vessels of the United States Navy.

Auxiliary ships which function as oilers are to be found in their own article: List of United States Navy oilers. Escort carriers, amphibious warfare vessels, and some mine warfare vessels were also originally classed as auxiliaries but were later given their own hull classification symbols outside 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 is indicated as either currently active [A] (including ready reserve), 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 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.

Historical overview

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.

World War I

During World War I 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 the end of the war and even fewer became naval auxiliaries.

Pre-World War II

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), 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.

In the late 1930's the Navy began the construction of 22 large tenders and repair ships to a new basic design: all were nearly identical in hull form, power plant, and superstructure (but the seaplane tenders had a large hangar that the others lacked):

• 5 destroyer tenders (AD)s of the Dixie-class
• 4 repair ships (AR)s of the Vulcan-class
• 7 submarine tenders (AS)s of the Fulton-class
• 2 seaplane tenders (AV)s of the Curtiss-class
• 4 seaplane tenders (AV)s of the slightly longer Currituck class

The last of these 22 ships (the submarine tender Sperry) was scrapped in 2011.^[1]

Also at this time the Navy began the construction of 4 large net layers (AN)s and 3 minelayers (CM)s to a different basic design, but changing requirements resulted in all but one minelayer being redesignated as transports (AP)s and then converted into Landing Ships, Vehicle (LSV)s.^{[A 1][2]}

World War II

During the naval build-up for World War II over 700 vessels of Maritime Commission (MarCom, later MarAd) standard designs were converted to US Navy auxiliaries,^{[A 2]} as were a few Landing Ships Medium (LSM)s:

• 58 Type B barracks barges: all APL

• 79 Type V ships: all AT
• 34 Type VC2 Victory ships: 3 AG,^{[A 4]} 29 AK, 2 AKS
• 4 LSMs: all ARSD

Post World War II

During the Cold War over 100 United States Maritime Administration (MarAd) standard designs were converted to US Navy auxiliaries:^{[A 5]}

• 8 Type C1 ships: 1 AF, 5 AGM,^{[A 6]} 2 AGS^{[A 7]}
• 3 Type C2 ship: 2 AE, 1 AG^{[A 8]}
• 4 Type C3 ships / CVEs: all AKV
• 4 Type C4 ships: 1 AG,^{[A 9]} 3 AGM^{[A 10]}
• 8 Type C5 ships: 3 ACS, 3 AK, 2 AVB
• 7 Type C6 ships: all ACS
• 7 Type C7 ships: 3 AK, 4 AKR
• 20 Type EC2 Liberty ships: 1 AGM,^{[A 11]} 16 AGR, 3 AGTR
• 2 Type R ships: both AF^{[A 12]}
• 2 Type S3 ships (LSTs): 1 AG,^{[A 13]} 1 AVB
• 17 Type S4 ships: 2 AGS, 13 AKV, 2 ARC
• 3 T2 tankers: all AGM^{[A 14]}
• 19 T3 tankers / CVEs: all AKV
• 31 Type VC2 Victory ships: 11 AG,^{[A 15]} 4 AF, 8 AGM,^{[A 16]} 4 AGS,^{[A 17]} 2 AGTR, 2 AKV
• 2 LSMs: 1 AG,^{[A 18]} 1 ARC

Modern auxiliaries have been designed to reduce operating costs by introducing scales of economies with larger ships and by reducing manning requirements (a trend begun in 1949 with 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).
