Was watching the news this morning. The US Navy is going to start teaching Navigation using the stars in the Naval Academy they said due to cyber warfare were GPS will be knocked out in time of war. Dam when did they stop teaching that. Maybe the Chronometer will be making a come back. We were taught to navigate with out GPS when I was in SBU XI we navigated from New Orleans to the Mobil River in the gulf of Mexico in four patrol boats the old fashion way with a chart about 2 days travel plus the return back to New Orleans after war games as training. Strange how the Navy lost there way since I been out . The sextant making a come back and maybe the chronometer.
