LORAN's gone everywhere I'm gonna boat.
The bad guys can't take the system out.... maybe jam it until we blow them off the face of the map as they would be interupting the entire world's safe commerce....or a more resonable approach would be to negate their jamming capability either electronically or precision "vaporizing".* I would love a backup to GPS but I doubt you'll ever see LORAN again.
If LORAN did come back...it would probably be LORANe at which point I would want a new receiver anyway.
OK with the nav/comms stuff...ANY OTHER reason to keep a bronze ground plate???
