HMS E21 was a British E class submarine built by Vickers, Barrow-in-Furness. She was launched on 24 July 1915 and commissioned on 1 October 1915. E21 was sold on 14 December 1921.

Design

Like all post-E8 British E-class submarines, E21 had a displacement of Шаблон:Convert at the surface and Шаблон:Convert while submerged. She had a total length of Шаблон:Convert[1] and a beam of Шаблон:Convert. She was powered by two Шаблон:Convert Vickers eight-cylinder two-stroke diesel engines and two Шаблон:Convert electric motors.[2][3] The submarine had a maximum surface speed of Шаблон:Convert and a submerged speed of Шаблон:Convert. British E-class submarines had fuel capacities of Шаблон:Convert of diesel and ranges of Шаблон:Convert when travelling at Шаблон:Convert.[1] E21 was capable of operating submerged for five hours when travelling at Шаблон:Convert.

E21 was armed with a 12-pounder 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.[2]

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

Crew

Her complement was three officers and 28 men.[1]
