Soviet Foxtrot class submarine

 U-475 Black Widow was a Soviet Navy submarine of the Cold war period, which is now in private hands. She is currently moored at Strood, on the River Medway, in South-East England.  Built at Sudomekh shipyard in Leningrad and commissioned in 1967. She was based at Riga and served with the Soviet Baltic Fleet before being used as a training vessel for crews from overseas who would be operating Foxtrot-class subs in their own navies. She was decommissioned in 1994 and sold.


The name "Black Widow" and the designation "U-475" were given to the boat by the new owners; Soviet submarines were not generally named, the "U-" designation was not used by the Soviets, and none of the Foxtrots known carried the number "–475".

In Soviet service she was actually known as B-49 and served in the Northern Fleet until November 1974 when she was reassigned to the Baltic.
