7 cm/50 (2.75") K10 and K16 Skoda
Updated 01 August 2006
Used as both anti-torpedo boats and as anti-aircraft guns in easily removable mounts.  Some of these were mounted on top of main gun turrets where they could be coupled with the 30.5 cm guns for gunnery practice.  The K16 was slightly different but had the same ballistic characteristics as the K10.

Actual bore diameter was 6.6 cm (2.6").
