I haven't seen any other data on how many aircraft are affected by U.S. military exercises involving GPS interference, but here's my attempt to analyze a 13-day exercise at WSMR in May. 4000 civilian aircraft with major GPS jamming: 90% were commercial jets. 30% were *outside* posted NOTAM hours.
After cleaning up my analysis, I believe I underestimated: I think about 4000 civilian aircraft flights had no GPS for at least 5 minutes during their flight because of GPS jamming during NAVFEST 2026.
