HMS C35 was one of 38 C-class submarines built for the Royal Navy in the first decade of the 20th century.

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 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 290 long tons (290 t) on the surface and 320 long tons (330 t) 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] 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.[1] They could reach 13 knots (24 km/h; 15 mph) on the surface and 8 knots (15 km/h; 9.2 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).[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

HMS C35 was built by Vickers, Barrow. She was laid down on 3 March 1909, launched 2 November 1909 and commissioned on 1 February 1910. HMS C35 was part of the British submarine operations in the Baltic from 1915 to 1918. She was scuttled at Helsingfors (now Helsinki) 1.5 miles (2.4 km) off Harmaja on 5 April 1918 to avoid seizure by advancing German forces. She was salvaged in August 1953 for breaking up in Finland.
