LC/25 triple-gun mount was the only mount used for this gun in the Kriegsmarine. The mount weighed between 136.91 - 147.15 t ton, depending on its armor thickness; the German cruiser Nürnberg 2's mounts had between 20 - 80 mm in on of armor while the other ships had 20 - 30 mm in on. Each mount was designed for full 360° of traverse, but was limited to much less than that by the ship's superstructure. The electrically powered hydraulic pumps had a maximum elevating speed of 8° per second, while train was a maximum of 6-8° per second. The maximum firing cycle was 7.5 seconds, or 8 rounds per minute, despite being hand-loaded and rammed. Ammunition was supplied by three hoists, one between the left and center guns and the other two between center and right guns at the rear of the mount.http://www.navweaps.com/Weapons/WNGER_59-60_skc25.htm German 15 cm/60 (5.9") SK C/25 20 November 2008 2009-06-23 Tony DiGiulian https://web.archive.org/web/20090815044426/http://navweaps.com/Weapons/WNGER_59-60_skc25.htm 15 August 2009 live Ammunition The SK C/25 had a number of different shells available.
