1948 May 26 - Launch Vehicle: Navaho. FAILURE: Failure. Nativ first attempted launch Agency: USAF. Apogee: 1.00 km (0.60 mi). First launch attempt of MX-770 technology demonstrator. Seven rockets were built in total. There is very inconsistent information on the flight series. One source speaks of six launches, another of four, and a third of three. It seems that there were six launch attempts, three of which never made it very far off the pad, two made it some distance aloft, and only one was considered somewhat successful (reaching Mach 2.23 and an altitude of 18 km).

1948 Q3? - Launch Vehicle: Navaho. Agency: USAF. Apogee: 15 km (9 mi).

1948 October 15 - Launch Vehicle: Navaho. Nativ Launch Agency: USAF. Apogee: 15 km (9 mi). On the most successful Nativ launch, the missile reached Mach 2.23 and an altitude of 18 km.
