JERUSALEM (Reuters) - Israel successfully tested its upgraded Arrow missile interceptor for the second time on Friday, pushing forward work on a U.S.-backed defence against ballistic threats it sees from Lebanon's Hezbollah guerrillas as well as from Iran and Syria.
One of several elements of an integrated Israeli aerial shield, Arrow III is designed to deploy kamikaze satellites - known as "kill vehicles" - that track and slam into ballistic missiles above the earth's atmosphere, high enough to safely disintegrate any chemical, biological or nuclear warheads.
