Design and description
[edit]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
[edit]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]
