Iron Fist (countermeasure)

Iron Fist (Hebrew: חץ דורבן, Hetz Dorban, lit. "Porcupine Arrow") is a hard-kill active protection system (APS) designed by Israel Military Industries (IMI), with a modular design allowing adaptation to a range of platforms ranging from light utility vehicles to heavy armoured fighting vehicles. The concept was revealed by IMI in 2006 and was expected to enter Israel Defense Forces tests by mid-2007. The system has been successfully tested against a wide variety of threats including rocket-propelled grenades, anti-tank guided missiles and tank-fired high-explosive anti-tank (HEAT) ammunition and kinetic energy penetrators.^{[citation needed]}

It senses incoming threats via a fixed active electronically scanned array^[1] radar sensor developed by RADA Electronic Industries and an optional passive infrared detector developed by Elbit's Elisra. When a threat is imminent, an explosive projectile interceptor is launched towards it. The interceptor explodes very near the threat, destroying or deflecting and destabilizing it by detonating its warhead. For this, only the blast effect of the explosive is used. The interceptor casing is made of combustible materials so minimal fragmentation is formed in the explosion, helping minimize collateral damage.
