Project history: Provided under the 1906 programme. Double-hull submersibles designed by Laubeuf - they were a diesel-powered version of Pluviôse class. MAN type diesels produced by A C Loire, Sautter-Harlé, Normand, Indret and Sabathé.
It was planned in 1917 to convert six boats of the Brumaire class into minelaying submarines but the project was abandoned.
Modernizations: 1916, Arago, Faraday, Le Verrier and others: + 1 x 1 - 47/50 M1902 or 1 x 1 - 75/35 M1897
7/1919, Curie was returned as given in the table

Naval service: Bernouilli was lost on Austrian mine 13.2.1918. Foucault was sunk by Austro-Hungarian aircraft off Cattaro 15.9.1915. Joule was mined in the Dardanelless 1.5.1915 on Turkish mine. Curie 20.12.1914 at attempt to get into harbour of Pola entangled in anti-submarine nets and was scuttled by crew. Later Austrians salvaged her and commissioned as U14; after war submarine was returned to France and received former name.
