Two stage. Launched 6 August 1964 at 02:45. Apogee 374 miles.

This was the first launch with the Gamma 301 motor rated at the full thrust of 21,600 lb, and all vehicle systems were successful. The re-entry head for this flight was a copper sphere, which was recovered the next morning. Although it had split into two and had been scored and dented by the impact with the ground, it was in surprisingly good condition.
