Dassault AVE Grand Duc
Full-scale stealth UCAV prototype cancelled in 2003.
The Dassault AVE Grand Duc was the planned full-scale prototype of the French LOGIDUC program, intended to be a 5,000 kg stealth combat drone (UCAV). It was the third and final vehicle in a series of three stealth aerial vehicles, following the AVE-D Petit Duc and AVE-C Moyen Duc scale models. The Grand Duc was cancelled in 2003 and replaced by the European nEUROn project.

Lore & Background
The Dassault AVE Grand Duc was the culmination of the LOGIDUC program, a French autonomous industrial initiative launched in 1999 by Dassault Aviation to develop UAV design capacities. The program aimed to produce a fighter-sized stealth UCAV to support the Dassault Rafale in the 2010s and to design autonomous stealth fighters for the French Air Force circa 2025. The Grand Duc was to acquire full mission system representativity, composite pack airborne control, collaborative flight with drones and aircraft, and live air-to-ground weapon release.
Like the earlier Petit Duc and Moyen Duc, the Grand Duc was named after an owl species: Grand Duc is the French name for the eagle owl. The program's naming convention used 'Duc' (duke) as the French name for a nocturnal bird of prey, with Petit Duc for scops owl, Moyen Duc for long-eared owl, and Grand Duc for eagle owl. The Grand Duc never reached the flying stage; it was cancelled in 2003 and its objectives were folded into the European nEUROn project.
Reader's Guide
The Dassault AVE Grand Duc represents a pivotal moment in European unmanned combat aerial vehicle development. As the intended full-scale prototype of the LOGIDUC program, it was designed to validate key technologies for a stealth UCAV that would complement the Dassault Rafale. Its cancellation in 2003 marked a shift from a purely national French effort to a collaborative European project, the nEUROn, which absorbed the Grand Duc's goals. The Grand Duc's planned capabilities—full mission system representativity, composite pack airborne control, collaborative flight with drones and aircraft, and live air-to-ground weapon release—highlight the ambitious scope of the LOGIDUC program. Although never built, the Grand Duc's legacy lies in the data and experience gained from the earlier Petit Duc and Moyen Duc flying prototypes, which informed the nEUROn demonstrator and subsequent European UCAV research. The program demonstrated France's commitment to developing autonomous stealth combat aircraft, a field that continues to evolve through multinational cooperation.
