The Škoda 15 cm K10 was developed and built by Škoda Works in Plzeň. The barrel was made of steel with a horizontal sliding breech block and the gun used separate loading ammunition with a cartridge case and bagged charge.

They were used as secondary armament on the four battleships of the Tegetthoff-class. Each ship had six guns per side mounted on pedestal mounts in casemates amidships. After World War I Tegetthoff was delivered to Italy as a war reparation. Tegetthoff was decommissioned and remained in Venice until 1923 when it was moved to La Spezia to be scrapped in 1925. The guns recovered from Tegetthof were assigned to coastal batteries in Libya and Croatia where they were used in World War II. The barrel, pedestal and semi-circular armored shield from the casemates were reused, but the mounts were modified to increase elevation to +35 ° and traverse to 360°. The only remaining complete 15 cm/50 gun of the four-gun battery Batterie Madonna is located on the island of Veli Brioni near Pula, Croatia. The engravings on this gun have been obscured by rust, but it appears that this gun is serial number 15 and was manufactured in 1912.
