When I left the Navy in '98 we were already pretty well networked through satellite communications and GPS technology. I always wondered what the impact would be if these networks were disrupted. For all it's whizzbang wonders and the accuracy and efficiencies produced, I always feared we were becoming to dependent on technology. On my last cruise, we almost exclusively relied on GPS, myself and a couple of others were the only ones to bother with a sextant and celestial navigation. Judging from what I see on the military channel this is really a dangerous development for the military.
