Flight Journal 06/2014

In early 1939, just months before WW II erupted in Europe, the Kriegsmarine formulated Plan Z, a construction program expected to be completed in 1948. It included ten battleships, three battlecruisers, and four carriers. The lead ship of the Flugzeugträger class was named Graf Zeppelin, a logical connection to Germany's dirigible pioneer. A sister ship to be named Peter Strasser (after the Great War Zeppelin commander) was scrapped during construction. Adolf Hitler pledged his support to the Kriegsmarine, with Graf Zeppelin's keel being laid by Deutsche Werke at Kiel in December 1936. She was launched two years later. Originally planned for 18,000 tons, her 361-foot length gained another 10,000 tons but she was originally rated at more than 33 knots. By the end of 1939, with Germany at war, she was 85% finished. All warships have long lead times, but especially aircraft carriers. Graf Zeppelin's progress was complicated by the fact that Reichsmarshal Hermann Goring owned nearly everything that flew in Nazi Germany. Therefore, her air group would belong to the Luftwaffe. Britain operated under the same policy until almost the last minute, as the Royal Air Force provided aircrews and planes to the Royal Navy. Britain's Fleet Air Arm, organic to the RN, only gained independence in May 1939. Realizing that it was starting far behind Britain and the U.S., in 1935 the Kriegsmarine sent a study group to Japan during the large carrier Akagi's modernization. From 1940 onward, the Imperial Navy kept a large delegation in Germany to offer advice and to report back on Graf Zeppelin's progress. We can only wonder what Japan's accomplished aviators and sailors thought of their ally's approach to the esoteric art of carrier aviation. Surely they recognized the practical limitations of the sled launch and compressed-air catapults.
