The Rivers were
built in 1931-1935. They were the closest thing to a successful fleet
submarine design produced by the British Navy, and had excellent
surface
speed and a less miserable range than most British submarines. Two
units were transferred to the Far East. Because their design sacrificed
so much for speed, they were relatively unmaneuverable and tended to
leak diesel fuel from the tanks located between their pressure and
outer hulls. However, they had a relatively large cargo capacity,
which allowed them to be used as supply submarines in the
Mediterranean. They were probably the most successful prewar British
design.
