HMS E10 was a British E class submarine built by Vickers, Barrow-in-Furness. She was laid down on 10 July 1912 and was commissioned on 10 March 1914. She costed £105,700. E10 was lost in the North Sea on or around 18 January 1915.

Design

Like all post-E8 British E-class submarines, E10 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. E10 was capable of operating submerged for five hours when travelling at 5 kn. As with most of the early E class boats, E10 was not fitted with a deck gun during construction, and it is not known whether one was fitted later, as was the case with boats up to E19. 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.
