U.S., Israel Sign Deal to Tackle Iran's Long-Range Missiles
Israel and the U.S. have signed an agreement to make the Arrow II ballistic shield capable of shooting down missiles at a higher altitude, the Israeli Defense Ministry said on Sunday. The Arrow III will allow Israel "to deal with the threat of ballistic missiles with long range" and will give it "the ability to shoot down weapons of mass destruction outside the atmosphere," the ministry said. Israel, which describes its Arrow system as a defense against Iran, says the upgraded version will cap off its multi-tier air defenses.
The IDF plans to operate three anti-missile systems: Iron Dome, to tackle rockets with a shorter range of up to 60 km.; David's Sling, which has a range of hundreds of kilometers; and the Arrow III, designed to shoot down missiles outside the earth's atmosphere. (Reuters-Ha'aretz)
