Supercavitation technology creates a gas bubble around the submarine, drastically reducing water resistance and enabling unprecedented underwater speeds. Advanced systems now overcome earlier limitations, maintaining stable cavitation at various depths and speeds. The technology incorporates highly developed control systems and specially designed hull shapes to sustain the gas envelope and ensure directional stability. While challenges remain in maintaining stealth during high-speed operation, recent breakthroughs in bubble generation and control have made this technology more feasible for military applications.
