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 cost £105,700. E10 was lost in the North Sea on or around 18 January 1915.
Like all post-E8 British E-class submarines, E10 had a displacement of 662 tonnes (730 short tons) at the surface and 807 tonnes (890 short tons) while submerged. She had a total length of 180 feet (55 m) and a beam length of 22 feet 8.5 inches (6.922 m). She was powered by two 800 horsepower (600 kW) Vickers eight-cylinder two-stroke diesel engines and two 420 horsepower (310 kW) electric motors. 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). E10 was capable of operating submerged for five hours when travelling at 5 knots (9.3 km/h; 5.8 mph).
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 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. Their maximum design depth was 100 feet (30 m) although in service some reached depths of below 200 feet (61 m). Some submarines contained Fessenden oscillator systems.
