Farfadet-class Submarine
The ''Farfadet'' class consisted of four submarines built for the French Navy at the beginning of the 20th century designed by Gabriel Maugas. Two boats were lost in diving accidents. All were disposed of prior to the outbreak of the First World War. Design and description The ''Farfadet''s were designed by Gabriel Maugas, an early French submarine engineer at the Arsenal de Rochefort, Rochefort Naval Dockyard. The ''Farfadet''s were single-hulled, and powered by electric motors only, limiting their range and surface performance compared to the contemporary ''Sirene'' class. However they had Variable-pitch propeller (marine), variable-pitch propellers, developed by Maugas, obviating the need for a reversing engine. The submarines Displacement (ship), displaced surfaced and submerged. They had an length overall, overall length of , a beam (nautical), beam of , and a draft (hull), draft of . They had an Submarine depth ratings, operational diving depth of . Their crew numbered 2 ...

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...
