HMS C21 was one of 38 C-class submarines built for the Royal Navy in the first decade of the 20th century. The boat survived the First World War and was sold for scrap in 1921.

Design and description

The C-class boats of the 1907–08 and subsequent Naval Programmes were modified to improve their speed, both above and below the surface. The submarine had a length of Шаблон:Convert overall, a beam of Шаблон:Convert and a mean draft of Шаблон:Convert. They displaced Шаблон:Convert on the surface and Шаблон:Convert submerged. The C-class submarines had a crew of two officers and fourteen ratings.[1]

For surface running, the boats were powered by a single 12-cylinder[2] Шаблон:Convert Vickers petrol engine that drove one propeller shaft. When submerged the propeller was driven by a Шаблон:Convert electric motor.[1] They could reach Шаблон:Convert on the surface and Шаблон:Convert underwater. On the surface, the C class had a range of Шаблон:Convert at Шаблон:Convert.[3]

The boats were armed with two 18-inch (45 cm) torpedo tubes in the bow. They could carry a pair of reload torpedoes, but generally did not as they would have to remove an equal weight of fuel in compensation.[4]

Construction and career

C21 was laid down on 4 February 1908 by Vickers at their Barrow-in-Furness shipyard, launched on 26 September and was completed on 18 May 1909. During World War I, the boat was generally used for coastal defence and training in home waters. C21 was sold for scrap on 5 December 1921.
