The Vultee XP-68 Tornado was proposed American high-altitude interceptor aircraft. It was based on the experimental XP-54 Swoose Goose and powered by the Wright R-2160 Tornado 42-cylinder radial engine driving a set of contra-rotating propellers in a twin-boom pusher configuration. When the engine was cancelled on 22 November 1941, the XP-68 was also cancelled.
