Canet gun

The Canet guns were a series of weapon systems developed by the French engineer Gustave Canet (1846–1913), who was design engineer for Schneider et Cie of Le Creusot.

Canet developed a 12.6 in (32 cm) 38 cal naval gun, an extremely powerful weapon for its time, specifically for the export market. The gun was first selected by the Spanish Navy in 1884 as part of a large naval expansion program which called for six new battleships. The Spanish armaments firm Hontoria obtained a manufacturing license to produce the weapon, but due to budgetary reasons, only one vessel, the Pelayo, was completed.

Canet was more successful in sales to the Empire of Japan, when the gun was selected by the French military advisor and naval architect Louis-Émile Bertin as the main battery of the Matsushima-class cruiser, new type of cruiser he had designed in 1887. The usage was consistent with the Jeune École philosophy, which advocated placing overwhelming firepower (strong guns, torpedoes) on relatively small ships. This philosophy was of great interest to the Imperial Japanese Navy, which lacked the resources at the time to purchase modern pre-dreadnought battleships.

The guns supplied to Japan equipped the cruisers Matsushima, Itsukushima, and Hashidate. Each gun weighed 67 tons, and had a barrel 12 meters long, firing a 112 mm long projectile with weight of 350 kg (or 449 kg high explosive) for an effective range of 8000 meters.
