Just because something works, we don’t necessarily need it. Such is the case with Fire Scout, a Navy unmanned helicopter that operates from small ships, though it can fly 115 miles or so from its mother ship. But is there any reason to have an unmanned helicopter that operates at sea? One that, in the era of a fully networked global intelligence system, is redundant. One that would be highly vulnerable in a real war with a peer adversary. Is it just because we can? That unmanned everything is now within reach? There’s nothing wrong with Fire Scout per se, but in its story is an interesting parable: That just because something isn’t attracting Washington enemies bellowing about cost or “fraud, waste and abuse,” doesn’t mean we should keep using it.
