    The U.S. Military Is Finally Testing Shotgun-Based 'Force Field' Technology

    Years ago, Israeli defense outfit Rafael developed the equivalent of a “bubble shield” for military vehicles. The Trophy Active Protection System basically blasts incoming missiles into oblivion with a turreted shotgun. Now this tech is finally running on American M1 Abrams tanks and Stryker armored vehicles.

    Active protection systems like Trophy are increasingly important in asymmetrical wars like the United States has tended to fight over the past few decades. Tanks can cost millions of dollars, are stuffed with actual, living humans, and are covered in many layers of the toughest armor known to humanity, but some rocket-propelled grenades can slice through them like a hot knife through butter.

    That’s a problem. But if a tank could stop the RPG from getting close before it made a contact, it could go a long way towards increasing its own survivability. That’s how systems like Trophy work:



    The Trophy is a radar rigged paired with shotgun-like weapons that destroy projectiles moving toward itself. It has conceptually been around for over a decade, but we’ve only seen it in action in the field within the last couple years.

    Much like its much larger Iron Dome cousin, Trophy – which is called Windbreaker locally – tracks objects rapidly approaching the vehicle it is mounted on, via an array of fixed radar antennas placed around the vehicle. The system automatically predicts the objects trajectory and then instantly aims a launcher that fires a canister of ball bearings at high speed directly at the object.

    Trophy is completely automated and capable of responding to an incoming projectile much faster than a human could, even at close range.

    And it does seem to actually work. Back in 2014, video emerged of an RPG being fired at an Israeli Merkava Mk IV tank during one of the country’s many conflicts with Gaza, and the Trophy system was seen easily swatting the RPG out of the sky:



    Coupled with electronic jamming systems, it seems to work pretty well.

    Lt. Gen. Robert Walsh, deputy commandant for combat development and integration, explained in a USNI report that testing is finally about to begin on American armor, after years of deployment in other countries:

    To that end, the Marine Corps is partnering with the Army to test out the Israeli Trophy Active Protection System (APS). The Army is leasing four systems and will experiment with their Stryker combat vehicle and M1A2 tanks. The Marine Corps is currently modifying some of its M1A1 tanks to install mounts for the Trophy system, and the service will later work with the Army to test the protective system on the Marine tanks against anti-tank guided missiles and RPGs, he told USNI News after the hearing.

    The United States Navy already uses technology on its warships using similar ideas, Walsh explained, but the issue with land vehicles is even more complicated.

    Weapon systems like tanks and Stryker armored personnel carriers are – strangely enough I know – stuck to land. And because of that, they’re limited in how big they can be and how heavy they can be. As Walsh touched upon in the USNI report, you can’t just keep slapping more and more armor onto them. Either they become too unwieldy to use in battlefield environments, bogged down with overtaxed engines and infrastructure, or they become more and more expensive, with no guarantee that the armor will be able to stop current-generation projectiles, let alone next-generation ones.

    That’s where countermeasure systems like Trophy come in to play. In a perfect world, a vehicle equipped with such a system wouldn’t need any hard armor. The incoming artillery shells, missiles, and rocket-propelled grenades would never even touch the vehicle.

    As it stands, the Army will reportedly test four such systems in Stryker vehicles and M1A2 tanks while the Marines will modify some of their own M1A1 tanks to mount the Trophy system.

    Oh my God its about time. I hope we can get a good deal on these from Israel, after all we did pay for the development of the Iron Dome. After a decade of war we are getting APS.

    Its still a new technology, the Israelis have only had it in service for a few years.Military programs generally take years so I am actually impressed that this is going so quickly.

    Our Strykers with the upgraded weapons and now with an APS will be very effective. They are silent, carry a lot of firepower, and now have very good protection.
