Korrigan was one of four Farfadet-class submarines built for the French Navy at the beginning of the 20th century.
Derived from the Morse by Gabriel Maugas,[1] the Farfadets were single-hulled, and powered by electric motors only, limiting their range and surface performance compared to the contemporary Sirène class. However they had variable-pitch propellers, developed by Maugas, obviating the need for a reversing engine.[2]
The boats displaced 185 metric tons (182 long tons) on the surface and 202 metric tons (199 long tons) submerged. They had an overall length of 41.35 meters (135 ft 8 in), a beam of 2.9 meters (9 ft 6 in), and a draft of 2.7 meters (8 ft 10 in). The crew of all of the submarines numbered 2 officers and 12 enlisted men. The boats were powered by a pair of Sautter-Harlé electric motors providing a total of 300 metric horsepower (296 bhp; 221 kW), both driving the single propeller shaft. The boats were fitted with side-thrusting propellers (French: évoleurs) at the stern to assist in steering. They could reach a maximum speed of 6.1 knots (11.3 km/h; 7.0 mph) on the surface and 4.3 knots (8.0 km/h; 4.9 mph) underwater. The Farfadet class had a surface endurance of 430 nautical miles (800 km; 490 mi) at 5 knots (9.3 km/h; 5.8 mph) and a submerged endurance of 28 nmi (52 km; 32 mi) at 4.3 knots (8.0 km/h; 4.9 mph).[2]
The boats were armed with four external 450-millimeter (17.7 in) Tissier torpedo launchers, two aimed forward and two aimed to the rear.[2]
