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. 

​​​BYMS 2045, Flotilla 170/152 in 1943, 170/180 in 1944 (known to be in 170 in June 44) 180 in 1945.

BYMS, British Yard Mine Sweeper were all built to the same design. The only variation was one of appearance in the number of exhaust stacks. They were fitted with an Acoustic “hammer” on the bow to sweep for acoustic mines and a drum on the stern for the LL cables to sweep magnetic mines.
