This is how a Humvee can stop an RPG

The Humvee — High Mobility Multipurpose Wheeled Vehicle (HMMWV) — has been a workhorse for the United States military for over three decades. The vehicle is showing its age, as insurgents have been doing a lot of damage with improvised explosive devices and RPGs. While the former can be a problem, the humble HMMWV may soon have a counter in the form of an active protection system.

Wait, you might be saying, aren't active protection systems a tank thing? Well, not necessarily. Yes, they can be heavy, but they don't have to be. According to a handout from General Dynamics at the Association of the United State Army expo in Washington, D.C., there is an active protection system that can fit on a HMMWV – or bigger vehicles.

The Iron Fist Light is a system that comes in at 551 pounds. Yep, you did not miss a fourth digit there. This means that the cargo carrying capacity of most vehicles is not seriously compromised. The system can be bolted on to just about any vehicle and uses both infra-red and radar systems to track incoming missiles and rockets. Then, it can fire an interceptor to destroy or deflect the incoming projectile.

The system works in both open terrain and urban environments, and also offers the ability to detect other types of hostile fire, such as bursts from small arms. The system provides 360 degrees of coverage and can also handle high-angle shots. Furthermore, it doesn't draw a lot of electrical power from the vehicle.

The Iron Fist was originally developed by Israel Military Industries. It was selected by the Army for use on vehicles last year, and will also be fitted on Dutch infantry fighting vehicles. One thing for sure, the HMMWV, which will be around for a while, is not going to be an easy target for bad guys.
