Shock Tactics
The US Navy is considering a defence system that destroys incoming
torpedoes by firing high-powered acoustic shockwaves at them. Ships
with the system would be decked out with hundreds of transducers,
each 1 metre square, running along the hull under the waterline.
When an incoming torpedo is detected, the transducers fire a focused
pulse of such crushing force that the incoming weapon is disabled or
destroyed. As you might imagine, these are no ordinary loud
speakers...
