HMS H43

HMS H43 was a British H class submarine built by Armstrong Whitworth at Newcastle upon Tyne. She was laid down on 4 October 1917 and commissioned on 25 November 1919, with a complement of twenty two. She displaced 423 long tons on the surface and 510 long tons submerged, was 171 feet long, and carried four 21 inch bow torpedo tubes with eight torpedoes; she was a Holland 602 type boat designed to Royal Navy specifications. In July 1940 she landed Lieutenant Hubert Nicholle on German occupied Guernsey for a reconnaissance and recovered him three days later. One of only seven H class boats to survive to the end of the Second World War, she was sold in November 1944 and scrapped at Troon in 1945.
