15 cm/60 (5.9") SK C/25

History

This weapon was used on light cruisers built in the 1920s and 1930s and was slightly more powerful than the 15 cm guns used on battleships and destroyers. The Germans considered this weapon to be too heavy and powerful for any other 15 cm (5.9") application.

The main components of this gun were the loose barrel, a jacket and a breech end-piece with a vertical sliding wedge breech. The breech mechanism was hand worked. The guns were individually sleeved in the three-gun mountings.

All German 15 cm guns had an actual bore diameter of 14.91 cm (5.87 in).
