The GZ never would have made it out of the channel. First of all the British aircraft in the area would have far out numbered the Luftwaffe and she would not have had sufficient carrier support from BB's, Cruisers, and Destroyers.
As far as I know, the hull of the Peter Strasser was only about 60 percent completed before she was scrapped. They already had one white elephant on their hands, with the Graf Zeppelin.
Yeah the Peter Strasser was never even close to being finished. Atleast the GZ resembled an aircraft carrier. She deffinatly would have been a beautiful ship and would have been neat to see today.
