H39

 I've just added a hypothetical German ship the H39 class of battleships that was part of the abandoned Z plan. 

As stated on the photo the name is pure guesswork and could be easily changed. I've left the Class name as H39 but I assume this would have also be changed to a Class name (if it had ever been built).

The aircraft is modelled coming out of the hanger. I assume 'Y' turrets guns would have had to be raised to their maximum to allow it to launch (looking at where the catapult is).
