HMS Selene was a S-class submarine of the third batch built for the Royal Navy during World War II.

[2] For surface running, the boats were powered by two 950-brake-horsepower (708 kW) diesel engines, each driving one propeller shaft.

[1] HMS Selene built by Cammell Laird & Co Limited, Birkenhead and launched on 24 April 1944.

[4] It survived the war and in the early 1950s was modified to become a fast unarmed underwater target to train anti-submarine personnel.

Its bridge superstructure was reduced to little more than a blister with a small cockpit in it, and it had only a single periscope.
