On 16 November 1935, the contract for "Flugzeugträger A" (Aircraft carrier A)—later christened "Graf Zeppelin"—was awarded to the Deutsche Werke shipyard in Kiel. Construction of the ship was delayed since Deutsche Werke was working at capacity, and the slipway needed for "Graf Zeppelin" was occupied by the new battleship , which was launched on 8 December 1936. Work started on "Graf Zeppelin" on 28 December, when her keel was laid down. She was launched on 8 December 1938, the 24th anniversary of the Battle of the Falkland Islands, and she was christened by Helene von Zeppelin, the daughter of the ship's namesake. At the launching ceremony, Hermann Göring gave a speech. By the end of 1939, she was 85% complete, with a projected completion by the middle of 1940. By September 1939, one carrier-borne wing, "Trägergruppe" 186, had been formed by the Luftwaffe at Kiel Holtenau, composed of three squadrons equipped with Bf 109s and Ju 87s.
