HMS E43 was a British E class submarine built by Swan Hunter, Wallsend. She was laid down on 22 December 1914 and was commissioned on 20 February 1916. On 19 January 1917 E43 collided with E36 off Harwich in the North Sea; E36 sank with all hands. E43 was sold on 3 January 1921 but became stranded under tow west of St Agnes Head, Cornwall on 25 November 1921.
Design
Like all post-E8 British E-class submarines, E43 had a displacement of 622 tonnes (686 short tons) at the surface and 807 tonnes (890 short tons) while submerged. It had a total length of 180 feet (55 m)[1] and a beam length of 22 feet 8.5 inches (6.922 m). It contained two diesel engines each providing a power of 1,600 horsepower (1,200 kW) and two electric motors each providing 840 horsepower (630 kW) power.[2] Its complement was thirty-one crew members.[1]
The submarine had a maximum surface speed of 16 knots (30 km/h; 18 mph) and a submerged speed of 10 knots (19 km/h; 12 mph). British E-class submarines had fuel capacities of 50 tonnes (55 short tons) of diesel and ranges of 3,255 miles (5,238 km; 2,829 nmi) when travelling at 10 knots (19 km/h; 12 mph).[1] E43 was capable of operating submerged for five hours when travelling at 5 knots (9.3 km/h; 5.8 mph). It was fitted with a 12 pounds (5.4 kg) quick-firing gun gun (12 pounder), five 18 inches (460 mm) torpedo tubes, and one spare torpedo tube. Its torpedo tubes were fitted at the front and the aft; unlike pre-E9 submarines, the two midship section torpedo tubes were not included.[1]
E-Class submarines contained wireless systems with 1 kilowatt (1.3 hp) power ratings; in some submarines, these were later upgraded to 3 kilowatts (4.0 hp) systems by removing a midship torpedo tube. Its claimed highest dive depth was 100 feet (30 m) although it was capable of reaching depths of below 200 feet (61 m). Some submarines contained Fessenden oscillator systems.[1]
