Armide-class submarine

The Armide-class submarines were a class of three diesel-electric submarines built for the Greek and Japanese Navies before and during World War I. They were built in the Schneider-Creusot shipyards 1913 to 1918, but were seized during the war by the French government before they could be sold. The Armide class ships operated in the Mediterranean during the course of World War I and were stricken from the Navy list between 1928 and 1935.

Design
56.2 m long, with a beam of 5.2 m and a draught of 3 m, The submarines had a surfaced displacement of 457 t and a submerged displacement of 670 t. Propulsion while surfaced was provided by two 2200 hp diesel motors built by the Swiss manufacturer Schneider-Carels and two 900 hp electric motors. The submarines' electrical propulsion allowed it to attain speeds of 11 kn while submerged and 17.5 kn on the surface. Their surfaced range was 2600 nmi at 11 kn, with a submerged range of 160 nmi at 5 kn.

The ships were armed with 4 to 6 (depending on the ship) 450 mm torpedo tubes and 1 × 47 mm L/50 M1902 Hotchkiss or 75 mm L/34 M1897 deck gun. The crew of one ship consisted of 31 officers and seamen.
