Project history

Single-hull type boats to a design by Maugas, 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.

Turquoise stranded in the Dardanelles 30.10.1915, was seized by the Turks, salvaged that day and commissioned 10.11.1915.

Modernizations

None.

Naval service

In December 1915 Müstecip Onbaşi was converted to floating battery charging plant for German submarines. She was stricken in October 1918, 1.7.1919 officially returned to France and in 1921 broken up at Istanbul.
