Thanks to its global coverage, its peacetime capabilities and its availability, ballistic missiles Early Warning (EW) space systems are identified as a key node of a global missile defence system. Since the Gulf war in 1991, several feasibility studies of such an Early Warning system have been conducted in France. The main conclusions are first that the most appropriate concept is to use infra-red (IR) sensors on geo- stationary orbit satellites and second that the required satellite performances are achievable and accessible to European industries, even if technological developments are necessary. Besides that, it was recommended to prepare the development of the EW operational system, by demonstrating its achievable performances on the basis of collected background images and available target IR signatures. This is the objective of the "EW optical space demonstrator", also named SPIRALE (this a French acronym which stands for "Preparatory IR Program for EW"). A contract has been awarded early 2004, by DGA/SPOTI (French Armament Procurement Agency), to EADS Astrium France, with a significant participation of Alcatel Space, to perform this demonstration.
