French orbital launch vehicle. In December 1961 France decided to demonstrate an indigenous satellite-launch capability, using stages in development for its ballistic missile program. Following careful evolutionary development, Diamant was successful on its first attempt in 1965. Improved versions were flown over the next ten years.

Failures: 10. Success Rate: 76.19%. First Fail Date: 1964-06-15. Last Fail Date: 1973-05-21. Launch data is: complete.

Status: Retired 1975.
First Launch: 1964.06.10.
Last Launch: 1975.09.27.
Number: 42 .
