BYMS 2031
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. 

MINE SWEEPING FLOTILLA:  156th MSF, Mediterranean : 2031, 2056, 2068, 2072, 2073, 2187, 2190, 2209.

Built by: American Car and Foundry Co., Wilmington, Delaware, USA.
Laid down: 11 May 1942.  
Launched:  7 September 1942
Handed over to Royal Navy: 13 March 1943
Returned to USA: 10 July 1947 and sold to Anthonio Theuma, Malta. Re-named Nanridi.
Seized for tobacco smuggling at Palermo, Sicily.

SPECIFICATIONS:

Wooden hull. Length, 130 feet. Beam, 25 feet 6 inches. Depth, 12 feet I inch. Draft, 8 foot 10.5 inches. Displacement 207-215 tons.

Engine: Two 800 bhp General Motors diesel engines.

Speed: 14.6 knots. 10 knots while sweeping. (Eight knots with double Oropesa sweeps)

Range: 2,500 at ten knots.

Compliment: 3 officers and 27 men.

Armament: One 3-inch HA/LA gun and two Oerlikon anti-aircraft guns.

BYMS’s were fitted with a drum on the stern with LL (double L) cables for sweeping magnetic mines, an acustic hammer on the bow for sweeping acustic mines and Oropesa floats for sweeping tethered mines.

All YMS and BYMS were built to the same design, the only variation was in the number of exhaust stacks. Minesweepers 1 to 134 had two sacks, 135 to 480 had one stack, 466 to 479 had no stacks.
