Design and description
The C class was essentially a repeat of the preceding B class, albeit with better performance underwater. The submarine had a length of 142 feet 3 inches (43.4 m) overall, a beam of 13 feet 7 inches (4.1 m) and a mean draft of 11 feet 6 inches (3.5 m). They displaced 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.
For surface running, the boats were powered by a single 16-cylinder 600-brake-horsepower (447 kW) Vickers petrol engine that drove one propeller shaft. When submerged the propeller was driven by a 300-horsepower (224 kW) electric motor. 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).
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.
Construction and career
C9 was laid down on 20 January 1906 by Vickers at their Barrow-in-Furness shipyard, launched on 3 April 1907, and completed on 18 June. During the war, the boat was generally used for coastal defence and training in home waters. C9 was sold for scrap in July 1922.
