British T Class Submarine - Group Two Boats

Group Two Boats

These seven vessels were all ordered under the 1939 War Emergency Programme. The first, Thrasher, was launched on 5 November 1940. The external bow torpedo tubes were moved seven feet aft to help with sea keeping. The two external forward-angled tubes just forward of conning tower were repositioned aft of it and angled backwards to fire astern, and a stern external torpedo tube was also fitted. This gave a total of eight forward-facing tubes and three rear-facing ones. All Group Two boats were sent to the Mediterranean, only Thrasher and Trusty returned.
