reclassified (MSC) meaning Minesweeper Costal. YMS-1 was completed 25
March, 1942 in City Island, New York. "Yard" refered to Naval Yard or
Naval Base. the YMS was used to to sweep mines laid by enemy
submarines. as early as 1942 off the ports of Jacksonville, Florida and
Charleston, South Carolina. The first 134 YMS's had two smoke stacks.

built by the Ballard Marine Railway in Ballard,
Washington (Seattle) as a Yard Mine Sweeper (YMS) class vessel. She was
classified as a Mark II design. YMS 328 was delivered on May 26 1943. She served in the
Aleutian
Islands during World War II, sweeping enemy mine fields at Attu and
U.S. mine fields at Kiska, and patrolling out of Adak. She was en route
