Crew of BYMS 2057.  Photos, thanks again to John Sterland.


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, 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

If you, your father or your grandfather have any additional information about this ship, crew lists, stories, photographs, please send copies of them to be added to our records and this website.

Thank you.
