The pan-European Neuron UCAV is making its public debut, outside Hall 2 here as part of the Dassault Aviation static display. But you could easily miss it. For security reasons, the stealthy, arrow-shaped drone has been enclosed in a dome, with the only public view being through a clear plastic curtain. Dassault is lead contractor, and France the lead country, for the six-nation technology demonstration project. The other participants are Greece (HAI); Italy (Alenia); Spain (EADS-CASA); Sweden (Saab); and Switzerland (Ruag).
