This incident, disinterred on Wednesday by Russian and Chinese sources, actually happened 18 months ago, It was revealed by DEBKAfile on June 23: Two missiles of the David’s Sling cutting-edge air defense system were launched against Syrian SS-21 missiles on Monday, July 23. One landed in Syria; the other one self-destructed. Both missed their targets. The IDF spokesman eventually came clean about what happened to the David Sling on its maiden combat mission. The built-in mechanisms of the two interceptors already in flight were ordered to self-destruct. Only one did. DEBKAfile’s now wonder why Chinese and Russian sites have decided to run this old story now. They report that Russian missile experts are studying the secret systems and features of the Israeli David’s Sling, which is designed to intercept medium-range ballistic and low-flying cruise missiles.
