Design and description
[edit]The C class was essentially a repeat of the precedingB class,albeit with better performance underwater. The submarine had a length of 142 feet 3 inches (43.4 m)overall,abeamof 13 feet 7 inches (4.1 m) and a meandraftof 11 feet 6 inches (3.5 m). Theydisplaced287 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 fourteenratings.[1]
For surface running, the boats were powered by a single 16-cylinder 600-brake-horsepower(447 kW)Vickerspetrol enginethat drove onepropeller shaft.When submerged the propeller was driven by a 300-horsepower (224 kW)electric motor.[1]They could reach 12knots(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 910nautical miles(1,690 km; 1,050 mi) at 12 knots (22 km/h; 14 mph).[2]
The boats were armed with two18-inch (45 cm)torpedo tubesin 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]
