The 15 cm SK L/40 was a German naval gun that was used as secondary armament on pre-dreadnought battleships, protected cruisers and armored cruisers of the Imperial German Navy in World War I. It was also used as a coast-defence gun during World Wars I and II.




Construction


The 15 cm SK L/40 gun was constructed of A tube, two layers of hoops and used a Krupp horizontal sliding-wedge breech block. It used separate loading metallic cased propellant charges and projectiles. Unlike other large naval guns of the time which used separate loading bagged charges and projectiles, this gun used charges inside of a brass cartridge case to provide obturation. The guns were often mounted in single casemates or single turrets amidships. In addition to guns produced for the Imperial German Navy comparable export models were produced for the Royal Netherlands Navy and produced under license by Škoda for the Austro-Hungarian Navy.




Naval Use


Ship classes that carried the 15 cm SK L/40 include:

Ammunition

The gun was able to fire:

Armor Piercing 51 kg (112 lb)
High Explosive Base Fuzed 45 kg (99 lb)
