The 15 cm SK L/45 was a widely used naval gun on many classes of World War I dreadnoughts and cruisers in both casemates and turrets. It was constructed of an A tube and two layers of hoops with a Krupp horizontal sliding-wedge breech block. During World War I a few pre-war cruisers that were armed with 10.5 cm guns were rearmed with these weapons. In World War II the 15 cm SK L/45 was widely used as coastal artillery and as primary armament on German auxiliary cruisers.
Ship classes that carried the 15 cm SK L/45 include:
Ammunition was of separate loading quick fire type. The projectiles were 61 cm (2 ft) long with a single bagged charge which weighed 13–14 kg (29–31 lb).
The same gun was used for coast defense duties in concrete emplacements after World War I. One example was 3./Marine-Artillerie Abteilung 604 ("3rd Battery of Naval Artillery Battalion 604") in Jersey.[2] They show it using 44 kilograms (97 lb) shells with a range of 18,000 metres (20,000 yd)
