The Émeraude class was a submarine - class of the French Navy in the First World War .
The single-hulled boats carried six 450 mm torpedo tubes , four of which were mounted in the bow and two in the stern. Reserve torpedoes were not carried. With the Émeraude class , deck guns were introduced on submarines for the first time in the French Navy . The last two boats built, Topaze and Turquoise , each had a 37 mm gun. The early French submarine design suffered from various problems. The boats had poor buoyancy on the surface and the diesel engine was too weak.
One boat was lost in World War I, another fell into enemy hands:
- The Saphir ran into a sea mine in the Dardanelles on January 15, 1915 and sank.
- The Turquoise was damaged by Ottoman gunfire on October 30, 1915 and ran aground. The Turks raised the boat and renamed it Mustadieh Ombashi . The Turkish Navy never put the captured boat into service. After the war ended, the submarine returned to France.
In November 1919, the Émeraude-class submarines were scrapped.
