The Israelis have Patriots and their own home grown system, should be interesting to see those side by side. Are you talking about the Arrow? It was developed with US assistance but Israel right now is the only one building or buying any. My (perhaps inaccurate) understanding was that it would be between the Patriot and the coming generation of American ABMs in effectiveness. Apparently it is now operational. ishitech.co.il "Selling arrows to the Indians Now that the U.S.-Soviet Anti-Ballistic Missile (ABM) Treaty is dead and buried, President Bush and Russian President Vladimir Putin are free to confront — cooperatively — the post-Cold War ballistic-missile threat. Coincidentally, Israel wants to sell India the Arrow ABM system we have cooperatively developed... ...In addition to terminal defense, we and the Israelis also cooperatively developed a boost-phase ballistic-missile intercept (BPI) capability. A ballistic missile is especially vulnerable in the boost phase, shortly after launch. It ascends rather slowly for several minutes, its intensely hot rocket exhaust making it a big fat target for infrared homing missiles. The Patriot-Arrow BPI capability involves: (1) detecting the ballistic missile, either before launch or within seconds after launch, and (2) having unmanned aerial vehicles (UAVs) — armed with heat-seeking missiles — within range of the launch point at launch time. The BPI capability utilizes "stealthy" UAVs, much akin to those we have used to great effect in Afghanistan: the low-flying Predator and the high-flying Global Hawk. The missile-armed Predator-like UAV, cued by our space-based assets, would attack stationary and mobile ballistic-missile launchers. It would use much the same all-weather sensor package and satellite command-and-control system our Predators used in Afghanistan. The Predator-like UAV needs to carry a missile with a bit more range than the Hellfire it carried in Afghanistan. What happens if the rogue missile gets launched and the low-flying Predator isn't close enough to destroy it? That's where the Hawk-like UAV comes in. Cued by our space-based assets, it will patrol a much larger area for days at a time, flying above 65,000 feet, high above the weather and anti-aircraft defenses. The Hawk-like UAV needs to carry a hypervelocity interceptor with as much slant range as possible. We developed — for terminal defense — such interceptors for the Arrow and Patriot. The Patriot PAC-3 interceptor weighs only 700 lbs., and has a range straight-up of about 12 miles. The Hawk-like UAV can carry one, perhaps even two." washtimes.com
