How long could Göring prevent carrier-aircraft development in Germany without a war?
Short answerNot indefinitely; once a carrier exists, the navy can expose the Luftwaffe's failure to supply aircraft directly to Hitler.
NotesGöring might delay cooperation once, but an operational Graf Zeppelin creates visible political pressure that is difficult to evade repeatedly. The Kriegsmarine can show Hitler a completed carrier and identify the Luftwaffe as the service withholding its air group. That does not guarantee a good German carrier force, because aircraft design, training, and operating doctrine still have to mature. Procurement outcomes depend on interservice bargaining and access to political authority as much as technical feasibility.
