 The LOGIDUC program consisted of a series of three stealth aerial vehicles, from scale 1/100 to 1/1, in view to collect data required by the production of a fighter-sized stealth UCLAV type supporting the Dassault Rafale in the 2010s and to design autonomous stealth fighters primary used by the French Air Force circa 2025.The two first vehicles, AVE-D and AVE-C, are scale model 1/100 (50kg) and 1/10 (500kg) stealth "tactical drones" (UAV), while the final version was to be a full-scale (5,000kg) prototype stealth "combat drone" (UCAV).Each vehicle was given an owl name as "Duc" ("duke") is the French name of a nocturnal bird of prey species known in Latin as "Otus" aka Scops owl.
