The British T-class submarine was a class of 53 diesel-electric ocean-going submarines built for the Royal Navy between 1937 and 1946, designed in 1934-1935 to replace the earlier O-, P-, and R-class boats and approved under the 1935 naval construction program. [1] [2] These vessels, also known as the Triton class, featured a riveted or welded pressure hull with a distinctive bulbous bow to.. The Royal Navy 's T class (or Triton class) of diesel-electric submarine s was designed in the 1930s to replace the O, P, and R classes. Fifty-three members of the class were built just before and during the Second World War, where they played a major role in the Royal Navy's submarine operations. Four boats in service with the Royal Netherlands Navy were known as the Zwaardvisch class. [2] At.
The Royal Navy's T class (or Triton class) diesel-electric submarines emerged in 1935 on paper to replace the early interwar O, P, and R classes. This was the start of a very long production unding in 1945, with 53 boats made. They played a major role for the Royal Navy, making the bulk of WW2 oceanic submersibles.. The basic design of the O, P and R-classes was now over ten old and even that of the S and Narwhal-classes was over five years old. With the re-armament of the country getting into its stride there was a strong case for a new design of patrol submarine to be produced. A patrol submarine capable of operating in the Far East was still required but one that was not too large for European waters.
