Vanguard TV-1 (Viking 14)
The Vanguard TV-1 was a two-stage test vehicle . The first stage was the Martin Viking type II slightly modified for the Vanguard program. The second stage was a prototype for the solid propellant Vanguard third stage, built by Grand Central. The second-stage payload was an instrumented nose cone. Primary goal was flight testing the new solid-stage for spin-up, separation, ignition, and propulsion performance. The secondary goal was for further evaluation of ground handling procedures, techniques and equipment, and in-flight vehicle instrumentation and equipment.
The flight was successful: flight operation and performance of all powerplant systems were very good. The vehicle was properly controlled throughout flight to an altitude of 12l miles and a range of 451 miles.
