An underwater airplane is an airplane capable of diving, is also called a submarine capable of flying, and is a new concept weapon under development, which can hit a target like a submarine under water and can fly like an airplane after rushing out of the water surface. The principle of a traditional underwater airplane is basically similar to that of a submarine. When the underwater airplane is submerged, the valve is opened, a certain amount of water is filled into the water tank of the airplane, and when the gravity of the airplane exceeds the buoyancy, the airplane is submerged. When the airplane needs to float out of the water surface, the airplane floats out of the water surface under the action of buoyancy larger than gravity as long as water in the airplane water tank is discharged. When submerged, the jet engine nacelle of an underwater aircraft is sealed and can be started quickly once it is out of the water.
