[4] JU-87C
* A carrier-capable variant of the Stuka, the "Ju-87C", was planned for the aircraft carrier GRAF ZEPPELIN. The Ju-87C featured:
* A catapult attachment.
* Arresting hook.
* Manually folding outer wing panels that hinged back along the fuselage.
* Flotation gear built into the airframe.
* A rubber life raft.
* Full cockpit heating.
* Jettisonable main landing gear.
The jettisonable landing gear was a puzzling feature. It clearly made ditching at sea easier, since the fixed landing gear would pitch the aircraft nose-over, and it apparently was also intended to help the crew escape if their Stuka was jumped by enemy fighters, allowing them to get away alive even if they had to splash or belly-in their aircraft. However, Germany never completed any aircraft carriers, and though some preproduction "Ju-87C-0" machines were manufactured beginning in the summer of 1939, the production "Ju-87C-1" variant was never built. It would have featured automatic wing folding.
Some of the Ju-87C-0s saw action in Poland. One had to drop its main landing gear, and German propaganda played up pictures of the machine to suggest that they had been shot off, with the Stuka proving so tough it made it back home anyway.
