BYMS 2021
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. 

In 1944 BYMS 2021 was meant to go to South-East Asia but did not go. 

BYMS 2021 was amongst the first vessels to enter Copenhagen, Denmark.
