The 10.5 cm SK C/33 was a German anti-aircraft gun used during World War II by the Kriegsmarine on a number of their larger capital ships. It was later adapted for Luftwaffe as a competitor to the famed 8.8 cm FlaK 18 as the 10.5 cm FlaK 38. In this role it proved to be too heavy for field use while having roughly similar performance as the 88, so was used primarily in static mounts. An improved version replacing the electrical gunlaying with a mechanical system was also introduced as the 10.5 cm FlaK 39.
