Up Key Field ANG Base in Meridian, Mississipi is unknown type with call sign ROKT. ICAO hex code AE6272 returns as unknown in database (see links). Not always, but often, this means it is a fairly new aircraft. PF is guessing F-35. Flight profile so far seems to indicate a pretty high performance capability. But no way to be certain. Apparently it is a rocket though.
