The T1s were
the first of one of Britain's most successful submarine design series,
being well-liked by their crews.
They were built from 1936-1942 and the design emphasized ease of
construction and maintenance. Since the naval disarmament
treaties were still in effect when they were designed, they were
held to less than 1400 tons displacement so that a large number could
be constructed within the treaty total tonnage limit. This limited
their surface speed. All ten of their tubes could be fired at a target
ahead, though only
six could be reloaded. (The remaining four were in external tubes on
the bow and amidships.) An eleventh tube was added to the stern in 1942
to improve their survival when under pursuit.
