While en route over eastern Nevada we were zapped by military jamming and lost all GPS and INS navigation.  Initially this caused some confusion in the flight deck as multiple ECAMS were rolling through and initially we didn't know the why.  We drifted left of course by approx a mile and were correcting back to an initial heading when ATC called to issue us a new heading towards INOYE.  I assumed the Flying Pilot duties and instructed the First Officer to run the ECAM and Pilot Monitoring duties.  Approximately 10 minutes later; we heard other aircraft telling ATC that navigation/transponder or auto flight failures were occurring.  That was when we first heard of the military jamming going on in the Warning Area.  We continued for another 20-30 mins on ATC issued headings and regained internal navigation capability.
