Graf Zeppelin Class Aircraft Carrier - Design and Construction

Design and Construction

After 1933, the Kriegsmarine began to examine the possibility of building an aircraft carrier. Wilhelm Hadeler had been Assistant to the Professor of Naval Construction at the Technical University of Berlin for nine years when he was appointed to draft preliminary designs for an aircraft carrier in April 1934. Hadeler's first design was a 22,000-long-ton (22,000 t) ship that could carry 50 aircraft and steam at 35 knots (65 km/h; 40 mph). The Anglo-German Naval Agreement signed 18 June 1935 allowed Germany to construct aircraft carriers with total displacement up to 38,500 tons, though Germany was limited to 35% of total British tonnage in any category of warship. The Kriegsmarine then decided to scale back Hadeler's design to 19,250 long tons (19,560 t), which would permit the construction of two ships within the 35% limit.

The design staff decided that the new carrier would need to be able to defend itself against surface combatants, which necessitated armor protection to the standard of a heavy cruiser. A battery of sixteen 15 cm (5.9 in) guns were deemed sufficient to defend the ship from destroyers. In 1935, Adolf Hitler announced that Germany would construct aircraft carriers to strengthen the Kriegsmarine. A Luftwaffe officer, a naval officer, and a constructor visited Japan in the autumn of 1935 to obtain flight deck equipment blueprints and inspect the Japanese aircraft carrier Akagi. The Germans also unsuccessfully attempted to examine the British carrier HMS Furious.

The keel of Graf Zeppelin was laid down on 28 December 1936, on the slipway that had recently held the battleship Gneisenau. The ship was built by the Deutsche Werke shipyard in Kiel. Two years later, Großadmiral (Grand Admiral) Erich Raeder presented an ambitious shipbuilding program called Plan Z which would build up the German Navy to a point where it could challenge the British Royal Navy in the North Sea. Under Plan Z, by 1945 as part of the balanced force the navy would have four carriers; the pair of Graf Zeppelin-class ships were the first two in the plan. Hitler approved the construction program on 1 March 1939. In 1938, a second carrier, ordered under the provisional name "B", was laid down at the Germaniawerft dockyard in Kiel. Graf Zeppelin was launched on 8 December 1938.

Famous quotes containing the words design and/or construction:

    Delay always breeds danger; and to protract a great design is often to ruin it.
    Miguel De Cervantes (1547–1616)

    When the leaders choose to make themselves bidders at an auction of popularity, their talents, in the construction of the state, will be of no service. They will become flatterers instead of legislators; the instruments, not the guides, of the people.
    Edmund Burke (1729–1797)
