We’ve written about the sci-fi sounding Army’s Future Combat System before, but the Army’s just demonstrated a successful test of one of its components: the Quick Kill vehicle defence system. Check it out: the Raytheon system uses an electronically-scanned radar array to detect an incoming anti-tank rocket-propelled grenade, then vertically launches a countermeasure missile that blows the round to smithereens in mid-flight, saving the RPG’s intended target. It’s a very simple test setup, and, of course the real system will have to deal with complications like vehicles in motion, but it’s an important first step. And it goes boom. [Danger Room]
