T Class

T Class submarines, designed in the 1930s, replaced the O, P and R classes. The construction programme included 53 boats in total, which made it the largest class of ocean-going submarines ever built for the Royal Navy. Their intended use was in action in the Far East against Japanese surface ships. They were superior to the O, P and R classes in that they had greater submerged speed, better surface and underwater handling and more torpedo tubes, although their surface speed was much lower.
