These guns were used as secondary armament on many pre-dreadnoughts and large cruisers of the late 1890s and early 1900s. A number of guns were exported to Austria-Hungary where they were used on a few ships. Guns were also used to arm the auxiliary cruiser Wolf, one of the more successful commerce raiders of World War I.
During the Second World War, this gun equipped a few transports and supply ships and was used in some coastal artillery batteries. Many of the latter were supplied with a new, more streamlined shell.
Spain acquired three of these guns in the summer of 1941 and these formed the Mesa de San Juan Battery located on the Island of Gran Canaria. The battery was deactivated in 1956.
Constructed of A tube and two layers of hoops. Used the Krupp horizontal sliding wedge breech block.
All German 15 cm guns had an actual bore diameter of 14.91 cm (5.87 in).
