British Yard Mine Sweeper
BRITISH YARD MINE SWEEPERS
BYMS’s were built in the United States and transferred the Royal Navy under the Lend-lease Programme. “British Yard Mine Sweepers” are so called because they were built to the same design as the US Navy’s “Yard Mine Sweepers”.
Crews for the BYMS’s would sail to the United States, often on the Queen Mary, which could sail unescorted because of her greater speed, to collect their vessel. They would then have the formidable task of sailing their small vessel back across the Atlantic Ocean, often in winter.
