**HMS *C10*** was one of 38 [C-class submarines](/source/British_C-class_submarine) built for the [Royal Navy](/source/Royal_Navy) in the first decade of the 20th century. The boat survived the [First World War](/source/First_World_War) and was sold for [scrap](/source/Ship_breaking) in 1922.

## Design and description

The C class was essentially a repeat of the preceding [B class](/source/British_B-class_submarine), albeit with better performance underwater. The submarine had a length of 142 feet 3 inches (43.4 m) [overall](/source/Length_overall), a [beam](/source/Beam_(nautical)) of 13 feet 7 inches (4.1 m) and a mean [draft](/source/Draft_(ship)) of 11 feet 6 inches (3.5 m). They [displaced](/source/Displacement_(ship)) 287 long tons (292 t) on the surface and 316 long tons (321 t) submerged. The C-class submarines had a crew of two officers and fourteen [ratings](/source/Naval_rating).[1]

For surface running, the boats were powered by a single 16-cylinder 600-horsepower (447-kilowatt) [Vickers](/source/Vickers) [petrol engine](/source/Petrol_engine) that drove one [propeller shaft](/source/Propeller_shaft). When submerged the propeller was driven by a 300-horsepower (224-kilowatt) [electric motor](/source/Electric_motor).[1] They could reach 12 knots (22 km/h; 14 mph) on the surface and 7 knots (13 km/h; 8.1 mph) underwater. On the surface, the C class had a range of 910 nautical miles (1,690 km; 1,050 mi) at 12 knots (22 km/h; 14 mph).[2]

The boats were armed with two [18-inch (45 cm)](/source/British_18_inch_torpedo) [torpedo tubes](/source/Torpedo_tube) 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.[3]

## Construction and career

*C10* was [laid down](/source/Laid_down) on 30 January 1906 by [Vickers](/source/Vickers) at their [Barrow-in-Furness](/source/Barrow-in-Furness) [shipyard](/source/Shipyard), [launched](/source/Ship_naming_and_launching) on 15 March 1907, and completed on 13 July. During [World War I](/source/World_War_I), the boat was generally used for coastal defence and training in home waters.

*C10* was part of the [6th Submarine Flotilla](/source/6th_Submarine_Flotilla), based on the Humber, but on 8 September 1914, the six submarines of the flotilla were sent to [Queensferry](/source/South_Queensferry) in the [Firth of Forth](/source/Firth_of_Forth) to search for and attack German submarines that had been active in the area. On 17 September, after the British battlecruiser force had left the Forth for [Scapa Flow](/source/Scapa_Flow), the 6th Flotilla was ordered to Cromaty to defend the approaches to Cromaty and Scapa Flow.[4]

On 3 May 1917, *C10* was fired on by the British destroyers [HMS *Ouse*](/source/HMS_Ouse) and [HMS *Bat*](/source/HMS_Bat) off [Blyth, Northumberland](/source/Blyth,_Northumberland). Although one man was killed and a second was wounded, the submarine survived.[5] *C10* was sold for scrap in July 1922.
