Now I've been looking all over the place so this is the second to last thing to do before I make myself go bald. There are two pieces under the fore hull of the Graf Zeppelin I have been tryin to figure out. Either they are an error or the devs know what they are. The reason I would like to find out is I am lovin the technical side of the ship and other vehicles in there games. As well as finding the history behind them, such as the the use of different props for the german R-boats. But this its messin with me.

I also had the same question, https://forum.worldofwarships.com/topic/200496-what-are-these-crowns-beneath-my-cvs-hull/?tab=comments#comment-4690337

many thanks to @mofton for the info.

I presume they were used in lieu of bow thrusters to allow for manouvring in harbours, or station keeping at sea.

Emergency Steering if I remember correctly. added after builders trials on Bismarck where she had proved to be difficult to steer without the rudders. (truly ironic considering how Bismark was sunk) Graf Zeppelin would have handled worse.

I had thought as much. When I looked at the prints I hadn't seen them and didn't  look at the prop. side of it. Plus I didn't gone through the forums. Thanks.

It wasn't due to Bismarck. I think she was designed with them early on. As I recall GZ's sides were so tall that they feared they would act as a sail and let the wind push her into the sides of the Kiel Canal or her dock. They feared her rudder alone wasn't enough to prevent that from happening at the low speeds needed to traverse the canal or move into her dock so they designed her with the Voith-Schneider thrusters to help her navigate at low speeds.

Depending on how detailed the prints are they will likely not show them. The retracted into the hull and were only intended for slow maneuvering. They were specifically to help going through the Kiel Canal and for docking. Other than Wargaming's model I've never seen them shown on any model or diagram. It's a really cool touch that Wargaming is showing them.
