I don't think it's China, but India!

China is reportedly developing a laser-propelled submarine capable of reaching jet-like speeds beneath the ocean’s surface — a potential leap in naval technology.

Unlike conventional subs that rely on propellers, this futuristic design could use directed energy propulsion, drastically cutting down drag and enabling supersonic underwater travel.

If successful, it could outrun torpedoes, evade sonar, and change how wars are fought at sea.

A stealthy, lightning-fast submarine might soon be a reality.
