On 18 February 1947, 39 Auxiliary Motor Minesweepers (YMS) were given names and redesignated AMS-1 through 39. Thus began the Motor Minesweeper (AMS) classification. The first 39 were followed in short order by 19 more former YMS' to make a total of 58. Intended for sweeping mines close to enemy shores and in shallow waters, this type of ship proved less than satisfactory. Their hulls, though made of wood, were too magnetic and susceptible to magnetic mines. In the early 1950's a new type of AMS that was nonmagnetic was laid down. Most of the new AMS', were under construction for loan to foreign countries under the Military Defense Assistance Pact.

To distinguish between the new nonmagnetic AMS' and the former YMS' rated as AMS', the Naval Classification system for mine warfare ships was revised. On 7 February 1955, all the World War II built AMS', still extant, were reclassified Coastal Minesweeper (Old) [MSC(O)]. All the new construction Auxiliary Motor Minesweepers were reclassified Coastal Minesweeper (MSC), starting with MSC-60.
