  • Diamant A French orbital launch vehicle. Diamant development could be done relatively quickly using stages and systems being developed for strategic missiles. In May 1962 CNES selected DMA as program manager, with SEREB as the prime contractor. The Diamant orbital launch vehicle was created by replacing the payload of the existing Saphir test vehicle with a new third stage. Prior to any all-up satellite launch attempt the P064 third stage was flight tested on the smaller suborbital Rubis test vehicle. This evolutionary approach paid off. More...

Associated Launch Sites
  • Hammaguira The constellation of launch complexes and nuclear weapons test sites established by France in Algeria began with the Special Weapons Test Center (CIEES). This began operations at Colomb-Bechar, Algeria, on April 24, 1947. Development of the larger Veronique series required a new facility. This went into operation at Hammaguir, 120 km southwest of Colomb-Bechar, in May 1952. The evacuation of these launch sites was a condition of the final agreement signed in March 1962 that ended the Algerian Civil War. The sites continued in use until finally turned over to the Algerian government on 1 July 1967. French missile test activities moved to Biscarosse, in France, and orbital launches to Kourou, in French Guiana. Hammaguira was known to have been used for at least 271 launches from 1952 to 1967.
