The 8.8 cm SK C/31[Note 1] was a German naval gun that was used in World War II.
The 8.8 cm SK C/31 gun weighed 4,255 kilograms (9,381 lb), had an overall length of 6.87 meters (22 ft 6 in) and its bore length was 6.341 meters (20 ft 9.6 in). It used a vertical sliding-block breech design. The gun was normally mounted on the twin Dopp LC/31, the mount plus guns weighed 27,300 kilograms (27.3 t). The Dopp LC/31 mount was later modified to carry the 10.5 cm SK C/33 naval gun. Useful life expectancy was fairly short 1,500 effective full charges (EFC) per barrel.[3] The 8.8 cm SK C/31 was briefly deployed on the Cruiser Lutzow. Lutzow's anti-aircraft battery originally consisted of three 8.8 cm SK L/45 naval guns, though in 1935 these were replaced with six 8.8 cm SK C/31 guns and in 1940, the 8.8 cm guns were removed, and six 10.5 cm L/65 guns were fitted.[4]
Fixed type ammunition with and without tracer, which weighed 18.5 kg (41 lb), with a projectile length of 1,227.5 mm (48.33 in) was fired. Ammunition Types Available:
