Ship project history: Constructed under the 1905 programme, laid down in 1906 and completed between October 1908 and January 1911. These 18 twin-hulled submarines (named after scientists and the Revolutionary months) were built to a design by Laubeuf. Their steam propulsion prevented them from submerging very quickly although in fact they were good sea boats. Despite their one main drawback the class were almost constantly employed during the war.

Modernizations: 1914, Pluviôse, Prairial, Messidor, Thermidor, Fructidor, Papin, Fresnel, Berthelot, Ampère, Gay-Lussac, Watt, Cugnot, Giffard: - 1 - 450 TT (bow)

Monge was sunk 29/12/1915 in the south Adriatic by the Austro-Hungarian cruiser Helgoland. Vendémiaire collided 8/6/1912 with French battleship Saint-Louis. Prairial collided 29/4/1918 off Le Havre with the British SS Tropic.
