The Dassault LOGIDUC – sometimes spelled Logiduc in French and LogiDuc in English – (Logique de Développement d'UCAV, French for "Unmanned Combat Aerial Vehicle development solution") was an autonomous industrial program launched in 1999 by the French aircraft manufacturer Dassault Aviation in view to develop its UAV design capacities.
This French programme eventually led to the creation of the Dassault-Sagem Tactical UAV company and to the European "combat drone" project nEUROn.
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.
