Right but they're heavier with far fewer weight concerns then an aircraft. Torpedos are large, heavy and expensive.

The point is a very thin wire had a surprisingly long range - versus this system which has a very low bitrate much past 1km.

For an active weapons system it's just not a great choice when you already have the wires and they work.

But for sensors or vehicle meshing, where you can't lay wires in advance? Potentially huge.
