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:
- SMS V106 torpedo boat (ex-Dutch)
- A-class torpedo boat (coastal)
- S90-class torpedo boat (ocean-going)
- Dresden-class cruiser
- Kolberg-class cruiser
- Königsberg-class cruiser
- Pillau-class cruiser
- Wiesbaden-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 SK L/40 gun in some older torpedo boats.[1]
