The tonnage limit led to proposals for smaller submarines which was also prompted by trials with larger submarines demonstrating that they were easier to find and lacked manoeuvrability. The Royal Navy was limited to no more than 52,700 long tons (53,500 t) of submarines by the London Naval Treaty of 1930. A further development was the British V-class submarine of 1942.

The class is sometimes known as the Undine class, after the first submarine built. The British U-class submarines (officially ' War Emergency 19 programmes, short hull') were a class of 49 small submarines built just before and during the Second World War.
