HMS E35

HMS E35 was a British E class submarine built by John Brown, Clydebank. She was laid down on 20 May 1916 and was commissioned on 14 July 1917.

E35 sank U-154 (one of the 1,512 ton U-boat cruisers originally designed as cargo carrying blockade runners) off the island of Madeira on 11 May 1918. This sinking was helped by British intelligence who had learned of a planned rendezvous between two U-boats off Cape St Vincent. E35 was sold in Newcastle on 6 September 1922.

Design

Like all post-E8 British E-class submarines, E35 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) 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. Its complement was thirty-one crew members.

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).E35 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.
