Associated Launch Sites
  • Ile du Levant In October 1950 a military missile test site was established at the French naval base on the Ile du Levant, an offshore island in the Mediterranean near Toulon. This was named CERES (Special Weapons Research and Tests Center) in 1952 and replaced a beach site at Pampelone used for ad-hoc launches since 1948. In 1968 it was expanded to include the La Renardiere site on Pont ST Mandrier and renamed CEM (Mediterranean Test Center). La Renardiere had been used in 1945 for testing the first French liquid propelled rocket, the EA 41. Ile du Levant was known to have been used for at least 111 launches from 1956 to 1969, reaching up to 270 kilometers altitude. More...
