U-10 Class Submarine

U-10 Class Submarine

The U-10 class was a class of five submarines or U-boats of the Austro-Hungarian Navy (German: Kaiserliche und Königliche Kriegsmarine or K.u.K. Kriegsmarine) during World War I. The class was similar to the German Type UB I submarine of the German Imperial Navy (German: Kaiserliche Marine); the first two boats delivered to Austria-Hungary had previously been commissioned in Kaiserliche Marine.

The U-10 class as a whole did not have much wartime success, with three of the boats sinking either one or no ships. Only one boat, U-15 sank more than 1,000 gross register tons (GRT) of enemy ships. Of the five submarines of the class, only U-16 was sunk during the war; the remaining four were delivered as war reparations and broken up by 1920.
