HMS E50 was a British E class submarine built by John Brown, Clydebank. She was laid down on 14 November 1916 and was commissioned on 23 January 1917. E50 was damaged in a collision with the Imperial German Navy submarine UC-62 while submerged in the North Sea off the North Hinder Light Vessel on 19 March 1917. E50 struck a mine in the North Sea off the South Dogger Light Vessel on 1 February 1918 and sank.


Like all post-E8 British E-class submarines, E50 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). E50 was capable of operating submerged for five hours when travelling at 5 knots (9.3 km/h; 5.8 mph).

E50 was armed with a 12-pounder QF gun mounted forward of the conning tower. She had five 18 inches (460 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.
