The Dassault Mirage 2000-5 and its derivatives are the result of an initially private venture by Dassault Aviation, aimed at providing Mirage 2000 interceptor aircraft with improved capabilities. This new slew of upgrades was centred around the Thomson-CSF RDY radar, an upgraded human-machine interface, the integration of MICA missiles and the ICMS Mk.II self-defence system for the export variants.
