HMS H43 was a British British H-class submarine constructed by Armstrong Whitworth in Newcastle Upon Tyne. Her keel was laid on 4 October 1917, and she entered service on 25 November 1919. The vessel accommodated a crew of twenty-two personnel. Notably, H43 was among the seven H-class submarines that remained operational through the conclusion of World War II. In November 1944, she was sold and subsequently dismantled at Troon in 1945.
Design
Following the design principles of post-H20 British H-class submarines, H43 displaced 423 long tons (430 t) when surfaced and increased to 510 long tons (520 t) submerged.[1] The submarine measured 171 feet (52 m) in length,[2] with a beam spanning [convert: invalid number], and had a draught of approximately 12 metres (39 ft).[3] Propulsion was provided by a diesel engine delivering 480 horsepower (360 kW), supplemented by two electric motors each rated at 320 horsepower (240 kW).[3] This configuration enabled a surface speed of up to 11 knots (20 km/h; 13 mph). Typically, the fuel capacity was around 16.4 long tons (16.7 t), with a maximum allowance of 18 long tons (18 t).[4]
The vessel could achieve a maximum velocity of 13 knots (24 km/h; 15 mph) on the surface and reach speeds of 10.5 knots (19.4 km/h; 12.1 mph) when submerged. These post-H20 H-class submarines were capable of covering approximately 2,985 nautical miles (5,528 km; 3,435 mi) cruising at 7.5 knots (13.9 km/h; 8.6 mph) while surfaced.[1][3] Armament consisted of an anti-aircraft gun along with four bow-mounted 21 inches (530 mm) torpedo tubes, loaded with a total of eight torpedoes.[1] Although based on the Holland 602 design, H43 was tailored to conform to Royal Navy standards. The standard complement included twenty-two crew members.[1]
Operational use
In July 1940, the submarine H43 transported Lieutenant Hubert Nicholle to German-controlled Guernsey for a reconnaissance mission and successfully retrieved him after three days.
