The U.S. military is worryingly dependent on GPS. Our global positioning satellites tell planes where they are, provide targeting info for smart weapons, and support communication and navigation systems. But in a war with a tech-advanced adversary—think China, Russia, or Iran—GPS could become a big liability because it could be jammed, spoofed, or outright destroyed.
So how does the U.S. Air Force train for such a scenario? Simple—just turn it off.I learned to navigate long before GPS was a thing. Map and compass, declination angles, back azimuths and terrain association. In tanks, compasses were useless. Sixty tons of steel plays havoc with a compass.A buddy of mine flew B-52s during the Vietnam war.. He could pick Polaris and Rigel our of the night sky in an instant.
GPS is cool, but when the balloon goes up, there is no guarantee that it will survive the opening shots. Soldiers, sailors, airmen and marines had best learn to get out the map and do stubby-pencil navigation. It might be the difference between life and death.
