| Operators of the Arrow 3 battery at Palmahim air base on the 
				Mediterranean coast canceled the launch of its interceptor 
				missile after it failed to lock on to a target missile fired 
				over the Mediterranean, the sources said.
 "There was a countdown to the launch, and then nothing 
				happened," one source told Reuters on condition of anonymity. "A 
				decision was made not to waste the interceptor missile."
 
 Arrow is among several elements of an integrated Israeli aerial 
				shield built up to withstand potential future missile and rocket 
				attacks by Iran, Syria or their guerrilla allies in Lebanon and 
				Gaza.
 
 In a statement, Israel's Defence Ministry said that "within the 
				framework of preparations for a future interception test, a 
				target missile was launched and carried out its trajectory 
				successfully".
 
 Asked whether Tuesday's trial had been intended as a full 
				interception that had failed, a Defence Ministry spokesman had 
				no immediate comment.
 
 Arrow 3 interceptors are designed to fly above the earth's 
				atmosphere, where their warheads detach to become kamikaze 
				satellites, or "kill vehicles", that track and slam into the 
				targets. Such high-altitude shoot-downs are meant to safely 
				destroy incoming nuclear, biological or chemical missiles.
 
 Arrow is jointly developed by state-owned Israel Aerospace 
				Industries (IAI) and U.S. firm Boeing Co. Its earlier version, 
				Arrow 2, was deployed more than a decade ago and officials put 
				its success rate in trials at around 90 percent.
 
 But an Arrow 2 interception test on Sept 9 ended inconclusively, 
				according to the Defence Ministry. The U.S. journal Defense News 
				later reported that the Arrow 2 interceptor missile missed its 
				target.
