Iron Fist (countermeasure)
Hard kill APS designed by IMI for light to heavy vehicles.
Iron Fist (Hebrew: חץ דורבן, Hetz Dorban, lit. "Porcupine Arrow") is a hard kill active protection system (APS) designed by Israel Military Industries (IMI). It features a modular design allowing adaptation to a range of platforms from light utility vehicles to heavy armoured fighting vehicles. The system senses incoming threats via a fixed active electronically scanned array radar sensor and an optional passive infrared detector, then launches an explosive projectile interceptor that destroys or deflects the threat by detonating its warhead.

Lore & Background
The concept of Iron Fist was revealed by IMI in 2006 and was expected to enter Israel Defense Forces tests by mid-2007. Acquisition was approved in June 2009 for installation on several units of the Namer armoured personnel carrier. In November 2010, the Israeli ministry of defense announced the end of funding of the system development. In May 2011, the system intercepted kinetic energy penetrators and Metis anti tank missiles during a test in the U.S.
In early 2013, the MoD tested both the IMI Iron Fist and Rafael Trophy in a competition to select a single second-generation APS for IDF vehicles. At the time, Trophy was already an operational second-generation APS (deployed on Merkava tanks since 2011), while Iron Fist was still in development. After 2013 trials, completion of a second-generation APS would be completed within a few years. In December 2014, Rafael, Israel Aerospace Industries, and IMI agreed to jointly develop a next-generation active defense system, with Rafael as main contractor and IMI providing the interceptor.
In June 2016, the U.S. Army chose to test the Iron Fist Light configuration for its light and medium armored vehicles. In December 2018, the Army revealed it would install Iron Fist on M2 Bradleys of one armored brigade. The new version, Iron Fist Light Decoupled, features a new countermeasure solution with a 70% successful intercept rate and the ability to counter drones. In December 2016, BAE Systems received a contract to test Iron Fist on CV9035 infantry fighting vehicles, with procurement decided in January 2021.
Reader's Guide
Iron Fist represents a significant development in vehicle active protection systems, offering a modular hard kill solution tested against a wide variety of threats including rocket-propelled grenades, anti-tank guided missiles, tank-fired HEAT ammunition, and kinetic energy penetrators. Its design emphasizes minimal collateral damage through the use of combustible interceptor casing materials. The system's history reflects the competitive and collaborative dynamics of Israeli defense procurement, including a period of suspended funding and later joint development with Rafael and IAI. International adoption by the U.S. Army and the Netherlands underscores its relevance, with the U.S. Army planning to field a brigade set in 2025. The system's evolution into the Iron Fist Light Decoupled configuration, with drone countermeasure capability, demonstrates ongoing adaptation to modern battlefield threats. Its integration onto platforms such as the Eitan APC, armored D9 bulldozers, and the Spanish Dragón VCR further illustrates its versatility across different vehicle classes.
Did You Know?
- The interceptor casing is made of combustible materials to minimize fragmentation and collateral damage.
- In May 2011, the system intercepted kinetic energy penetrators and Metis anti-tank missiles during a test in the U.S.
- The U.S. Army chose to test the Iron Fist Light configuration in June 2016 mainly because of the system's light weight.
- The Iron Fist Light Decoupled version has a 70% successful intercept rate and the ability to counter drones.
Frequently Asked Questions
What is Iron Fist (Hetz Dorban)?
It is an Israeli hard-kill active protection system that detects and destroys incoming projectiles before they can hit a vehicle. The Hebrew name literally translates to 'Porcupine Arrow.'
Who designed Iron Fist?
Israel Military Industries (IMI) is the company that developed the system. It was first shown to the public back in 2006.
How does Iron Fist actually stop an incoming threat?
Instead of a kinetic intercept, it launches a small explosive projectile whose warhead detonates close to the incoming round, using the blast to destroy or deflect it. The interceptor casing is built from combustible materials so it burns away after the burst.
What vehicles can Iron Fist be mounted on?
Its modular design lets the same sensor-and-launcher concept scale from light utility trucks up to heavy armoured fighting vehicles. This flexibility is a key selling point over bulkier reactive-armour solutions.
Why is Iron Fist important for modern armoured warfare?
It gives even lightly armoured ground vehicles a realistic layer of protection against anti-tank missiles and rockets without the weight penalty of thick composite or reactive armour. In that sense it extends survivability to the lighter end of the vehicle spectrum.
