To pile on here, one of my Commodores in the mid-2000's said: "There is nothing unmanned about unmanned platforms, aviation or otherwise." If you look at TRITON, the manpower requirements are jynormous. I know when unmanned, autonomous platforms were just a sparkle in the eye of the defense industry and DoD, drastic reductions in manpower was a yuge selling point. It really hasn't turned out that way.
