Largest joint US-Israel missile defense drill ... JPost - Defense US military forces have begun arriving in Israel to take part in the largest joint missile defense exercise of its kind, which will begin next week. One thousand American soldiers will arrive on Israeli territory, and a further 2,000 US troops in Europe and the United States will take part via remote defense computing systems. An equal number of Israeli soldiers will be involved.

American naval ships carrying the Aegis combat system, which can intercept missiles, will take part, and at least one US Navy ship will dock at Haifa. The IDF and the US military's European Command will set up missile defense batteries across Israel. Most of the drill will involve computer simulations of incoming rockets, though in the last stage, a Patriot will be fired at a mock enemy projectile. "Anyone can take away any message they want from this," said the IDF's Brig-Gen. Nitzan Nuriel, who is heading the Israeli side of the exercise. "The fact that we are working together is a strong message by itself," he added. Nuriel defined a successful program as "the interception of all incoming missiles to reduce damage to Israeli infrastructure." Air Force Lt. Gen. Craig Franklin, US Third Air Force Commander and the senior American commander in Israel for the exercise, said Washington will be spending 30 million dollars on the drill. Nuriel said Israel would be spending the same amount.
