China is reportedly working on a laser-propelled submarine that could achieve jet-like speeds underwater — a potential game-changer in naval warfare.
Ditching traditional propellers, this next-gen sub would use directed energy propulsion to slice through the ocean with minimal drag, possibly reaching supersonic speeds beneath the surface.
If successful, it could outrun torpedoes, dodge sonar, and redefine undersea combat as we know it.
A stealthy, lightning-fast submarine may no longer be sci-fi — it could soon be sailing through the depths.
