5.2 cm SK L/55 naval gun

The 5.28 cm SK L/55 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.

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:
 * SMS V106 torpedo boat (ex-Dutch)
 * A-class torpedo boat (coastal)
 * S90-class torpedo boat (ocean-going)
 * Dresden-class cruiser
 * Kolberg-class cruiser
 * Pillau-class cruiser

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 L/40 gun in some older torpedo boats.
