Lockheed Martin is now testing Cormorant, a stealthy autonomous spy jet that starts and ends its mission 150 feet under water. Launched from Ohio-class submarines, the four-ton aircraft is designed with folding wings that allow it to fit inside a Trident missile tube, which is about 48 feet long but just 7 feet wide.
