History:

A total of 561 "Yard Mine Sweepers" were built at various U. S. yards.  This type was not expected to go beyond adjacent waters from their base. Built at 35 yacht yards, rather than larger shipyards; 12 on the East Coast; 19 on the West Coast, and four in the Great Lakes. It has been established by the U. S. Navy that this is the reason for the "Yard" designation. Records show that YMS' were used in the United States Navy to sweep mines laid by enemy subs as early as 1942 off the ports of Jacksonville, FL and Charleston, SC. One of their greatest losses being on 9 October 1945, when seven U.S. YMS' were sunk in a typhoon off Okinawa.They served with distinction in the European, Med, and Pacific theaters. 

The wood-hulled YMS proved to be one of the U.S. Navy's more durable and versatile types through a quarter-century of service, filling a variety of roles for a number of navies. After WW2 ahbout a dozen navies acquired surplus YMS's.   Originally rated as service craft, they were used during World War II for inshore sweeping to prepare the way for amphibious assaults. Surviving YMS's were reclassified as AMS in 1947, given names, and rerated as mine warfare ships; in 1955 they received the new type symbol MSC(O), changed to MSCO in 1967. These ships bore much of the mine warfare burden in Korea, formed a major portion of our minecraft strength through the 1950's, and provided underway training for Naval Reservists in the 1960's. Ruff (MSCO-54), originally YMS-327, the last of her kind in U.S. service, was struck from the Navy List in November 1969. Many were converted as various vessels by private owners.  Jaques Cousteau's "Calipso" was a converted YMS.

Eighty ships of the 136-foot YMS type were ordered by the U.S. Navy specifically for transfer to Great Britain under Lend-Lease. For accounting purposes they were carried on the Navy List as "British Motor Minesweepers" (BYMS) and numbered in a separate sequence from 1 to 80. Upon transfer to Britain, BYMS-1 to BYMS-80 were assigned the British pendant numbers BYMS-2001 to BYMS-2080. Their general characteristics were identical to those of their U.S. Navy counterparts. Names were not assigned them by the Royal Navy.

Fifty-three more BYMS' bore hull numbers from 137 to 284. These were originally built for the U.S. Navy as YMS' and transferred to Britain on, or shortly after, completion.
