HMS E36

HMS E36 was an E-class submarine built by John Brown, Clydebank for the Royal Navy. She was laid down on 7 January 1915 and was commissioned on 16 November 1916.

E36 was sunk in a collision with HMS E43 off Harwich in the North Sea on 19 January 1917. There were no survivors. On 15 September 2013, Dutch fisherman Hans Eelman found a large metal object near the island of Texel, using sonar. The object was thought to be the wreck of a submarine of the E-type and was thought to be E36, but later reports proved it was not.

Design
Like all post-E8 British E-class submarines, E36 had a displacement of 662 LT at the surface and 807 LT while submerged. She had a total length of 180 ft and a beam of 22 ft. She was powered by two 800 hp Vickers eight-cylinder two-stroke diesel engines and two 420 hp electric motors. The submarine had a maximum surface speed of 16 kn and a submerged speed of 10 kn. British E-class submarines had fuel capacities of 50 LT of diesel and ranges of 3255 mi when travelling at 10 kn. E36 was capable of operating submerged for five hours when travelling at 5 kn.

E36 was armed with a 12-pounder 76 mm QF gun mounted forward of the conning tower. She had five 18 inch (450 mm) torpedo tubes, two in the bow, one either side amidships, and one in the stern; a total of 10 torpedoes were carried.

E-Class submarines had wireless systems with 1 kW power ratings; in some submarines, these were later upgraded to 3 kW systems by removing a midship torpedo tube. Their maximum design depth was 100 ft although in service some reached depths of below 200 ft. Some submarines contained Fessenden oscillator systems.

Crew
Her complement was three officers and 28 men.
