At the time the program was cancelled full-range G-38 missiles were in fabrication with first flight test planned by the end of 1958. The engines, missile frame manufacturing techniques, inertial and stellar navigation equipment, and telemetry/guidance techniques developed for Navaho established the technical basis for many subsequent US rocket developments.

Fired from AMR at 0159 hours EST, impacted at the predicted range. This success proved conclusively that the planned ablative-type heat protection for Jupiter warheads was satisfactory. The missile was a three-stage configuration--the first stage an elongated Redstone missile, the second and third stages 11 and 3 six-inch scaled Sergeant rockets, respectively. The one-third scale Jupiter nose cone was attached to the final stage with scheme for separation provided. The nose cone travelled to a 1,168 nm range, reached a velocity of 4,004 m/sec, and experienced a total heat input at stagnation point at 95% of that for the full scale nose cone at 1,500 nm. Naval units recovered the scaled nose cone according to plan. References: 2.
