Iron Fist Active Protection System
Definition/Scope: The Iron Fist Active Protection System (Iron Fist APS) uses a fixed radar sensor, mounted on the protected platform, to detect potential threats, measure distance and trajectory, providing the fire control system with data for calculation of engagement plans. When a threat is identified as imminent, an explosive projectile interceptor is launched toward it. The interceptor, shaped similar to a small mortar bomb, is designed to defeat the threat even when flying in very close proximity. Unlike other systems, the Iron Fist uses only the blast effect to defeat the threat, crushing the soft components of a shaped charge or deflecting and destabilizing the missile or kinetic rod in their flight. The interceptor is made of combustible envelope, fully consumed in the explosion. Without the risk of shrapnel, Iron Fist provides an effective, close-in protection for vehicles operating in dense, urban environment. The use of close proximity, rather than "hit to kill" mechanism avoids complex interception techniques and contributes to reduced cost. One of the main advantages of the Iron Fist is its integration into routine operations. Its sensor provides essential input to situational awareness systems, based on ground radar surveillance, moving target detection, classification and tracking and motion detection. Furthermore, by loading other types of projectiles, such as non lethal, anti-personnel, smoke or illumination, the system can be used in support of routine operation. The program is designed to protect medium and light vehicles, but based on its performance, has the potential to be fielded on heavy armor as well. In future configurations, the system has a growth potential to protect sensitive elements of fixed installations or patrol boats, protecting from RPG attacks, frequently encountered in counter insurgency operations.
