Canon de 65 mm Modèle 1891

The Canon de 65 mm Modèle 1891 & Modèle 1902 were a family of widely used naval guns of the French Navy that were also used by the Ottoman Navy during World War I. Guns removed from decommissioned ships also saw use as coastal artillery and as fortress guns in the Maginot Line fortifications during World War II.

Construction
The Canon de 65 mm Modèle 1891 & Modèle 1902 were developed and built by Schneider at the Le Creusot works. The guns were constructed of an A tube, a jacket, a wedge breech block, a locking ring, a trunnion hoop and used fixed quick fire ammunition. The Modèle 1891 & Modèle 1902 had similar dimensions, but the Modèle 1902 fired a slightly heavier projectile at a higher muzzle velocity. Both models are sometimes referred to as 9 pounders in English publications.

History
The Canon de 65 mm Modèle 1891 & Modèle 1902 were mainly used as anti-torpedo boat defense aboard armored cruisers, destroyers, ironclads, pre-dreadnought battleships, protected cruisers, seaplane carriers and torpedo gunboats.
