1/35 scale model of the 10,5 cm SK C/32.
​The 10.5 cm SK C/32 (SK - Schiffskanone (ship board cannon) C - Construktionsjahr (year of design), was a widely used German naval gun on a variety of Kriegsmarine ships during WWII. Originally designed as a surface weapon, it was used in a number of other roles such as anti-aircraft and coastal defence.

The 10.5 cm SK C/32 was a built-up gun, 45 calibers long, with a jacket and breech that weighed about 1.8 tons. The gun fired 10.5 centimeters (4.1 in) fixed ammunition, which was 1.51 m (5.0 ft) long, weighed 24.2 kg (53 lb) and had a 4.08-kilogram (9.0 lb) propellant charge. Useful life expectancy was 4,100 effective full charges (EFC) per barrel.

Surface ships

The 10.5 cm SK C/32 was widely deployed on three different types of single mounts. The high-angle MPLC/30 was a modified 8.8 cm mount. The low-angle MPLC/32 was used on Type 35 torpedo boats, Type 37 torpedo boats and Type 40 minesweepers. The high-angle MPLC/32 gE was used on the cruiser Emden, the battleship Schlesien, the battleship Schleswig-Holstein, Elbing class torpedo boats, Type 35 minesweepers and Type 43 minesweepers.

Two guns formed the main armament of the Romanian multi-purpose vessel Amiral Murgescu.

U-boats

The 10.5 cm SK C/32 was the standard low-angle deck gun mounted forward of the conning tower in type I, type IX and type X U-boats. The Ubts LC/32 mounting used in type I and early type IX U-boats weighed about 5 tonnes. Later type IX and type XB U-boats used the lighter Ubts LC/36 mounting with a maximum elevation of +30° . During the early war years, these guns were used to encourage surrender of independently routed merchant ships or to sink ships damaged by torpedoes.
