The 5.28 cm SK L/55[Note 1] was a German naval gun that was used before and during World War I on a variety of mounts, in torpedo boats and cruisers.

Design and description

The 5.2 cm SK L/55 gun was designed around 1905, and used fixed ammunition. It had an overall length of about 2.86 m (9 ft 5 in).[1] The gun was of built-up steel construction with a central rifled tube, reinforcing hoops from the trunnions to the breech. The gun used a semi-automatic Krupp horizontal sliding-block breech and used fixed quick fire ammunition.

Service

This gun was installed in several torpedo boats and cruisers of the Imperial German Navy, as well as in some torpedo boats ordered by the Royal Netherlands Navy, among them:

During World War I it was sometimes replaced with larger guns (as the 8.8 cm L/30, 8.8 cm L/35 or 8.8 cm L/45), while in turn replaced the less powerful 5 cm SK L/40 gun in some older torpedo boats.[1]
