Single-hull type boats to a design by Maugas, they were all built under the 1903 programme. Although proper submarines their surface buoyancy was not good; similarly their diesels were poorly designed which meant that trials were delayed and fraught with problems.
1915, Topase, Turquoise: + 1 x 1 - 37/40 M1902
Saphir sank in the Dardanelles after hitting a mine in 15.1.1915. Turquoise was damaged by Turkish gunfire and consequently beached on 30 October 1915. The Turks changed her name to Mustadieh Ombashi (or Müstecip Ombasi) after refloating her but she was not commissioned. She was condemned shortly after being returned to the French in 1919.
