The 15 cm Schnelladekanone Länge 35, abbreviated as 15 cm SK L/35, was a German naval gun developed in the years before World War I that armed a variety of warships from different nations. The navies of Austria-Hungary, China, Denmark, Japan, The Netherlands, The Ottoman Empire, Romania and Spain all used this gun.

History

In 1880 Krupp designed the 15 cm SK L/35 and started production in 1883 to arm protected cruisers, turret ships and coastal defense ships then under construction. It was also used to rearmed a number of earlier iron clad warships. Originally designed to use one piece ammunition 1.33 m (4 ft 4 in) long and weighing 68 kg (150 lb) the gun was redesigned to use two part quick loading cased charges and projectiles due to complaints about the size and weight of the ammunition. By breaking the ammunition down into two pieces the rate of fire was improved and crew workload was eased.[1]

Land use

In addition to its naval artillery role the 15 cm SK L/35 was also used as coastal artillery in either armored gun turrets or on garrison mounts. The garrison mount consisted of a rectangular steel firing platform which sat on a concrete slab behind a parapet with a pivot at the front and two wheels at the rear to give a limited amount of traverse. The recoil system consisted of a U shaped gun cradle which held the trunnioned barrel and a slightly inclined firing platform with a hydro-gravity recoil system. When the gun fired the hydraulic buffers under the front slowed the recoil of the cradle which slid up a set of inclined rails on the firing platform and then returned the gun to position by the combined action of the buffers and gravity.[5]

Ammunition

Ammunition was of separate quick loading type with a cased charge and projectile. The charge for AP and Common shells weighed 8 kg (18 lb). The charges for Shrapnel were 3.7–5.2 kg (8.2–11.5 lb).
