The graf zepplin was a german aircraft carrier, launched but never completed. It would have been a decent ship, but a single carrier would have been crushed in the theater, with RAF an RN aircraft attacking it the second they had the chance. However a single carrier launched before the war, and ready to go at the start could have posed a threat, as did the other elements of the Kreigsmarines surface fleet in the opening stages of the conflict. The carrier would have been equipped with the extended wing and carrier equipped Me-109T, and the Ju-87C, a carrier equipped, stuka with jettisonable landing gear and attachments for bombs or torpedoes. (some Me-109T's were built and would serve on short airfileds with a great service career, into 1944). Had the graf zepplin and and some other warships, preferably commerce raiders slipped into the atlantic on the first days of the war, they would have caused merry hell for the british...what are your thoughts?
