The 8.8 cm SK C/35 was a German naval gun used in World War II.
The 8.8 cm SK C/35 gun weighed 776 kilograms (1,711 lb) and had an overall length of 3.985 meters (13 ft 0.9 in) with a vertical sliding-block breech. The gun fired a 9.5 kg (21 lb) projectile 88 mm in diameter, and the barrel is sometimes described as 45 caliber. A 2.82 kg (6.2 lb) propellent charge produced muzzle velocity of 700 m/s (2,300 ft/s) with nose-fuzed high explosive and high explosive incendiary projectiles (with or without tracer). Useful life expectancy was 12,000 effective full charges (EFC) per barrel.
