The Pentagon has mysteriously tested a technology that can block GPS in front of a large area, and it is likely that this ability will also be used in the Nellis testing and training area for this Red Flag 18-1. Visual contact and distance affect the way GPS users, especially other aircraft operating well outside of the training area, are affected.
The fact that the Department of Defense will conduct widespread GPS jamming operations during such a high-end exercise is further evidence of the magnitude of the threat these new electronic warfare tactics pose. It will be interesting to see if the USAF admits that the technology was actually used for the Red Flag after the exercise is complete, but given the fact that quite a number of position, navigation, and timing technologies ( PNT) Loss of handheld gps jammer during combat, advisories like these occurring during major military exercises are likely to become more and more normal in the years to come.
