Ships in class: Several
Normally, each S-boat flotilla had its own S-boat tender, which was used to refuel and rearm the small fast attack craft and to serve as a floating barrack for the S-boat crews between their operations.
The Tsingtau was the first S-boat tender (Schnellbootbegleitschiff) which was build for the Kriegsmarine. Smaller than the later designs, it had many similarities with the U-boat tender Saar which was build at the same time.
The Carl Peters class was built to support an equip the fast attack boats with torpedoes, depth charges, ammunition, fuel and fresh water, in addition they were used as floating barracks and hospitals for the small S-boats.
