The invention discloses a high-submergence-depth underwater vehicle based on liquid jet and supercavity coupling resistance reduction and a driving method of the high-submergence-depth underwater vehicle. The power system for doing work through expansion of compressed gas is used for providing power for the underwater vehicle, meanwhile, waste gas of the power system generates supercavitation to reduce resistance of the vehicle, a traditional lithium battery underwater vehicle power system is replaced, the system compactness is improved by adopting the method that the power system and a resistance reduction system are coupled, and the navigation resistance is reduced. The navigational speed, the endurance time and the high-speed maneuverability of the underwater vehicle are effectively improved, and better benefits are obtained. In addition, a method of combining liquid jet with the cavitator is used as a supercavitation generation method, so that the endurance time of the aircraft is further prolonged, and the deep sea navigation capability of the aircraft is further improved.
