Lest there be any doubt, I did notice the smiley at the end of Alexandre's comment. At the same time, it wouldn't surprise me if various branches of the US military are trying to figure out what to do if GPS is jammed (and, yes, I know that at the military level it's pretty jam-proof) or becomes available in some circumstances ranging from solar storms to unexpected satellite outages. Not too long ago, the US Coast Guard was prevented from switching off Loran C to keep it as a backup.
