“铁拳”主动防护系统由以色列飞机工业公司埃尔塔（Elta）子公司研制的雷达，由埃尔比特/埃利斯拉（Elbit/Elisra）公司研制的快速反应红外传感器、拦截弹发射器以及计算机控制装置组合而成。安装在车辆周围的4块平板天线为其提供360°的水平探测以及未定大角度的垂直探测。雷达探测和跟踪近距离的来袭威胁物，而与雷达和红外传感器相连的控制装置则操纵拦截弹发射器，并确定是否或何时发射拦截弹。
有2个快速横向摆动的拦截弹发射器，一般位于车辆对角处，每个发射器覆盖270°弧面，以确保二者有一定的重叠度。每个发射器可人工装填2枚干扰弹或拦截弹。拦截弹通过在来袭威胁物附近爆炸来摧毁来袭威胁物，引爆时间在发射时预先设定，通过无线电向其发送指令信号。表面上拦截弹类似迫击炮弹，但它具有可燃药筒，因此发射时不会溅射破片，最大程度地减小了间接损害。
试验中，拦截弹的爆炸波充分证明了它能将反坦克火箭弹的聚能装药战斗部与其尾部断开，这将引起爆燃且不能起爆战斗部。在动能弹攻击的情况下，拦截弹在动能弹前面爆炸，并使动能弹向下倾斜，因而动能弹攻击的是一个偏斜的目标，这就大大减小了侵彻威力。
“铁拳”主动防护系统能够很容易地安装在从装甲人员输送车到主战坦克的装甲车辆上，目前正在研制应用在像美国“悍马”（HMMWV）一类轻型装甲车辆上的主动防护系统。在这期间，2套主动防护系统原始型样品中的一套已被安装在M113装甲人员输送车上，另一套则安装在美国制造的M60主战坦克的改进型Sabra MkⅢ上。
Iron Fist incorporates radar developed by the Elta subsidiary of lsraeI Aircraft Industries．infrared(IR)sensors for short response time developed by Elbit／Elisra, 1aunchers ofcountermeasures and a computerised control unit． Four flat-panel antennas installed around a vehicle provide 360°coverage for it in the horizontal plane and also a large but unspecified angle in elevation． The radar detects and tracks approaching threats at close range while the control unit, which is connected to it and the IR sensors, operates the launchers and determines whether or when to activate them．
There are two rapidly traversable launchers typically located at opposite corners of a vehicle and each covering an arc of 270°， which ensures a degree of overlap． Each launcher is armed with two countermeasures or’interceptors’which are loaded manually． The interceptors’kill’approaching threats by blast， being pre-set to explode near them at launch or by command signalssent to them by a radio link． In appearance the interceptors resemble mortar bombs but have combustible casings so that they do not spray fragments and therefore minimise collateraI damage．
During trials the blast of the interceptors’explosions proved sufficiently powerful to separate the shaped charge warhead of an antitank grenade from its tail， causing deflagration and not exploding it． In the case of attack by KE Projectiles the interceptors are exploded in front of them, to tilt them downwards so that they strike their targets yawed and therefore with much reduced penetration capability．
The Iron Fist svstem can be installed easily on vehicles ranging from armoured personnel carriers to main battle tanks and is being developed for use on vehicles as light as the US High-Mobility Multipurpose Wheeled Vehicle(HMMWV)． In the meantime one of two prototype systems has been installed on a M113 tracked armoured personnel carrier and the other on a Sabra Mk III, a modified version of the USbuilt M60 main battle tank．
