Description

Anti-aircraft weapon used to replace old 8.8 cm Flak 45 guns on the "K" class light cruisers. Later used on other German light cruisers and apparently exported to Spain. Although a less powerful gun than the 8.8 cm SK C/31, it had nearly equivalent performance and a much longer barrel life.

Construction was loose-barrel with a vertical sliding breech-block.
