Rubis was one of six Template:Sclass-s built for the French Navy (Marine Nationale) in the first decade of the 20th century.
Design and description
The Émeraude class were built as part of the French Navy's 1903 building program to a Maugas single-hull design.[1] The submarines displaced 395 metric tons (389 long tons) surfaced and 427 metric tons (420 long tons) submerged. They had an overall length of 44.9 meters (147 ft 4 in), a beam of 3.9 meters (12 ft 10 in), and a draft of 3.8 meters (12 ft 6 in). They had an operational diving depth of 40 meters (130 ft). Their crew numbered 2 officers and 23 enlisted men.[2]
For surface running, the boats were powered by two Sautter-Harlé 300-metric-horsepower (296 bhp; 221 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 300-metric-horsepower electric motor. They could reach a maximum speed of 11.26 knots (20.85 km/h; 12.96 mph) on the surface and 8.5 knots (15.7 km/h; 9.8 mph) underwater. The Émeraude class had a surface endurance of 2,000 nautical miles (3,700 km; 2,300 mi) at 7.3 knots (13.5 km/h; 8.4 mph) and a submerged endurance of 100 nmi (190 km; 120 mi) at 5 knots (9.3 km/h; 5.8 mph).[3]
The boats were armed with four internal 450-millimeter (17.7 in) torpedo tubes, two in the bow and two in the stern, for which they carried six torpedoes.[4]
Construction and career
Rubis was laid down in October 1903[5] at the Arsenal de Cherbourg, launched on 27 June 1907 and commissioned on 11 December 1909.[6]
