ELA-1, short for Ensemble de Lancement Ariane 1 (French for Ariane Launch Area 1), also known as Ensemble de Lancement Vega, ELV, and CECLES, is a launch pad at the Centre Spatial Guyanais in French Guyana. It has been used to support launches of the Europa rocket, Ariane 1, 2 and 3, and is currently being rebuilt as a launch site for the future Vega programme.
