Israel in partnership with the US Missile Defense Authority performed a successful test, its second, early Friday on the Arrow 3 missile interceptor. The Israeli defense ministry said a new version of the system was put through its paces in and outside the atmosphere “according to a preset plan and targets” for testing improvements adapted to future challenges to Israel’s security. DEBKAfile adds: The system is designed to intercept and destroy a hostile ballistic missile heading for Israel close to its launching pad.  Although the test was important, it was just one in a series. The Arrow 3 is still under development and will not be ready for operational service before 2016.
