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. The stealthy drone quietly floats to the surface and goes about its business of putting the hurt on those who hate America, and then when all the killing is done, slips back under the waves to be retrieved by a sneaky robotic underwater vehicle. Testing should be done by September, when the Defense Advanced Research Projects Agency (DARPA) will decide if it will commission a flying prototype. So it's not real yet, but even so, this has to be one of the coolest-looking airplane drawings ever, which was done, incidentally, by John MacNeill Illustration.
