Israel's Iron Dome is Not So Iron
Designed by the Israelis to shoot down the incoming Hamas\Hezbollah Iranian made rockets based on the Soviet Grad short range missiles, it has been only moderately successful. The system is not perfect yet it does work, though not 100% effective. The recent deluge of rockets falling upon Israel in the past few days has shown that out of 530 rockets only 184 from Gaza were intercepted, the remaining hit and exploded. Facing the Gaza, there are four Iron Dome systems, each with 3-6 launchers and each launcher has 20 interceptor rockets. The cost effectiveness has shown that it is not so. Most of the rockets fired from Gaza cost only a few hundred dollars while one Iron Dome costs between $30-100,000.
To not waste interceptor rockets, Israeli soldiers have tweaked the computer systems and tracking so that only rockets with a probable trajectory of a city or town will be intercepted, while those destined to hit farmland or less populate areas, will not. Israel is also developing another interceptor system called David's Sling, which will intercept longer ranged missiles for the Lebanon border area, like Iran's Shahab-3 or Syrian Scuds. Also, the Arrow, is another Israeli system that will intercept long range ballistic missiles.
