Spanish
24 cm/42 (9.45") Model Canet-Guillen
Updated 09 May 2006
By the middle of the 1890s, the Spanish Naval Ministry was investigating a replacement for the obsolete 24 cm Hontoria gun, which was the standard weapon for most of their larger ships.  Brigadier de Artilleria de la Armada Don Enrique Guillen, with the help of the French armament firm of Schneider, designed a more modern weapon based on previous Hontoria and Canet designs.  The mountings for these weapons used electric motors for most functions.

The Italian-built Cristobal Colon was sunk during the Spanish-American War before her guns could be installed.
