The delivery of an upgraded interceptor currently being installed on Israel’s Arrow anti-missile batteries will ramp up its ability to cope with threats from Syria and Iran, Agence France Presse reported Thursday, August 9. “The upgraded Block 4 system will significantly improve the accuracy of the existing Arrow 2 missile defense system,” an official at the Israeli defense ministry said. He was referring to the latest upgrade of Israel’s cutting-edge missile interception program that began as a joint project with the United States in the 1980s. “We find ourselves in a technological race whereby our defense systems must keep up with offensive threats,” the source said. The Block 4 upgrade incorporates a new generation of radar and other technologies which will be synchronized with U.S. systems that are already in use in the region.
