Aiming at the difficult questions that working principle of super-cavit underwater vehicles and the formation of super-cavity are very complex, super-cavit under vehicles ballistic visual simulation system was firstly developed. The framework structures of this kind of underwater vehicles visual simulation system were designed. The simulation environments including sky, surface and underwater were established by making use of the Vega Prime and the C＋＋. After investigation on the working principle of super-cavit underwater vehicles, the 3D the super-cavity model was devised some main visualization functions were realized, such as the launching, navigating, disengaging the auxiliary engine, forming of the super-cavity, and attacking process. etc. The navigation processes of the super-cavit underwater vehicles were perfectly simulated The simulation result shows that the models fidelity, the specific effect, and the visualization impression effectively reflect the real process. Engineers and scholars can achieve intuitionistic and clear cognition during the research process of super-cavit under vehicles. The work satisfies requirements for investigation on super-cavit underwater vehicles.
