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.
