A similar system is also under development in israel – ‘Invisible Reactive Armor Protection (IRAP)’ utilizing the ‘Blax Fox’ thermal camouflage system from Eltics and IMI’s hybrid armor technology. In the U.S., DARPA and the U.S. Army research and development center have pursued similar capabilities for future spirals of the ‘Manned Ground Vehicle’ – the core maneuver element of the now terminated Future Combat System.
