With the advancement of computers and satelites I can sit at my machine and do some pretty snazzy things what with Google Earth or whatever the sat program is and almost scan the world. OK cant tell the time on Big Ben. That aside and back to the sats, modern warships and in particular submarines must surely be more advanced than some old bloke on a PC. By that I mean at periscope depth an arial or antenna capable of looking anywhere on the earth or sea via one of the many satelites in orbit around the planet. This would be a huge plus for " boats" with the missiles etc and a massive advantage over skimmers. It seems even night is no obstacle now with infra red so during an "attack" could a submarine attack team sit in a lounge type setting as if playing a PC game. The ming boggles but it seems anything is possible so is this technology used or have I been watching too many James Bond films, :roll:
