The Force Aerienne Populaire de Benin has ordered two Grand Duc to monitor their coastlines around the capital Porto-Novo. The Grand Duke is a so-called “aerial territory surveillance system” and differs from the original version only in its comprehensive on-board instrumentation including autopilot, equipment for night flying, GPS, Iridium satellite communications, transponder, digital camera, Geobox system for tracking the aircraft from the ground, etc. The first production Ellipse appeared at the June 2011 Paris Air Show, painted in the colours of the Air Force of Benin.
