Das boot ist kaputt: German navy has zero working subs | Ars Technica:
"Germany has a submarine problem. During a test dive in October, the Deutsche Marine's U-35 struck something (probably a rock) with one of its four "X-rudders," the steering planes on its rear fins. 
The damage required the submarine to be towed back to a shipyard in Kiel for repairs—where it joined three other German navy submarines currently drydocked. 
The U-35 was the Deutsche Marine's only working submarine prior to the collision. 
The remainder of the German submarine fleet is in port at the German naval base in Eckernförde—waiting for dry docks in Kiel to open up.
...As a result, Germany's entire submarine service is left essentially sitting on its hands through at least the first half of 2018.
