General info

Although the 12.7 cm SK C/34 may not pack as much of a punch as its 150 mm rivals, it makes up for it with its rather quite impressive reload speed, being able to fire 18 rounds per minute on average with a full ready-rack, and 15 rounds per minute otherwise.

Available ammunition

The 12.7 cm SK C/34 can fire three types of ammunition.

The default shell is the Sprgr. Kpf.Z high explosive shell with 1.905 kg of TNT equivalent and a muzzle velocity of 830 m/s. It is most effective against small motor boats, as it has a high chance of causing hull-break.

The next shell is the Sprgr. Bd.Z, a base-fused HE shell with more penetration in most cases but with less explosive mass, only 1.4 kg of TNT equivalent and the same muzzle velocity of 830 m/s. It is most effective against armoured targets, such as other destroyers.

The last shell is the Sprgr. Zt.Z, it has 1.905 kg of TNT equivalent and has a time-fuse to detonate after an automatically set amount of time. It is most effective against airplanes and slower gun motor boats.
