Shields Up!
November 8, 2004: Rocket propelled grenades (RPGs) are the typical weapons of choice when someone wants to attack trucks and armored vehicles in Iraq. RPGs are cheap, simple to operate, and if used properly can inflict significant damage on Stryker and Bradley armored vehicles. Unarmed and armored Hummers are especially vulnerable, since the various armor kits for the Hummer are designed to protect occupants from small arms and machine gun fire, not anti-tank grenades.One quick fix to protect the Hummer is a unique airbag system developed by a small California company that deploys a "curtain" down outside the side of the vehicle being attacked. Four bags are needed to protect all quadrants and are held in place with simple Velcro straps. A small radar detects the incoming RPG or RPGs and inflates the airbag with a carbon dioxide gas cartridge. The RPG is literally "caught" by the airbag like a pillow and slowed enough so the nose-mounted fuse doesn't detonate the warhead. Instead, the RPG ends up collapsing upon itself, shredding the secondary self-destruct fuse and looking like a stomped-on beer can. Currently, the airbag and cartridge have to be replaced after one use, but the designers are working on a reusable airbag that can simply be rolled up and put back into place.
