List of mine warfare vessels of the United States Navy



This is a list of mine warfare vessels of the United States Navy.

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.

Historical overview
Mine warfare consists of: minelaying, the deployment of explosive naval mines at sea to sink enemy ships or to prevent their access to particular areas; minesweeping, the removal or detonation of naval mines; and degaussing, the process of decreasing or eliminating a remnant magnetic field in a ship's hull to prevent its detection by magnetic mines. The US Navy has operated ships and craft for all three purposes. Mine planting is the laying and maintenance of controlled mines for harbor defense, which was traditionally a role of the US Army.

Classifications
Mine warfare ships were originally considered by the US Navy to be either auxiliaries or yard and district craft, and so were given hull classification symbols beginning with either 'A' or 'Y', depending on their capabilities. The exceptions were four converted cargo ships with ID numbers (prior to the modern hull system), certain large 'cruiser' minelayers which were given hull symbols beginning with 'CM', converted destroyers which were given hull symbols beginning with 'DM', and three unclassified civilian cargo ships after World War II.

On 7 February 1955 all of these ships and craft still in service or reserve were reclassed and received new hull symbols beginning with 'M', usually without change of hull number. The exception was the degaussing ships, which retained the 'A' hull symbol.

Modern Littoral Combat Ships use 'L' hull symbols even though they can be used for mine warfare.

All ACMs except USS Buttress and USS Monadnock were originally US Army mine planters.

Minesweepers (Special device) (MSS)
Note that the official classification of these as devices rather than ships accounts for these ships absence of listings among the Navy's ships while designated MSS-1 and MSS-2.
 * MSS-1, ex-Liberty ship Harry L. Glucksman
 * USS Washtenaw County (MSS-2), ex-LST-1166

Submarine minelayers (SM)

District auxiliary, miscellaneous (YAG)
Three Liberty ships were converted into experimental minesweepers.
 * Floyd W. Spencer (YAG-36)
 * John L. Sullivan (YAG-37)

Another Liberty ship, the SS R. Ney McNeely, was also converted into an experimental minesweeper, but was returned to the reserve fleet without having a YAG number assigned.

Motor mineplanters (YMP)
Mineplanters were used to plant and maintain controlled mines for harbor defense; since the US Army had the primary responsibility for these minefields it is likely that the YMP hull designation was seldom used.

Littoral combat ships (LCS)
The Littoral Combat Ships can carry mine warfare modules which operate unmanned vehicles of various types for mine clearance operations.

Unclassified civilian minesweepers
After the end of World War II three war-damaged civilian ships with skeleton Navy crews and automated engineering spaces were used as minesweepers to trigger still-active US pressure mines in Japanese waters. There ships were not Navy ships and were to be disposed and therefore were not assigned Navy hull classifications. Reportedly no active mines were found.
