HMS E39 was a British E class submarine launched by Palmers, Jarrow in 1916 and was completed by Armstrong Whitworth, Newcastle upon Tyne. She was laid down on 18 May 1916 and was commissioned in October 1916.[1]

HMS E39 was sold on 13 October 1921, but in December 1922 she foundered in Watwick Bay at the entrance to Milford Haven, Pembrokeshire, while on tow to the shipbreakers.[2]

Design[edit]

Like all post-E8 British E-class submarines, E39 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)[3] 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.[4] Its complement was thirty-one crew members.[3]

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).[3] E39 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.[3]

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.[3]
