The US MDA has started delivering key components for the David's Sling Weapon System (DSWS) to the Israeli Air Force.
The surface-to-air missile system was successfully tested in December last year.
The Israeli Defence Ministry was quoted by media sources as saying: "In the first stage, project managers from the administration in charge of developing missile defences together with military industries, headed by the prime contractor, Rafael, will begin handing over the interception, command and control, and radar systems."
A statement on the Israeli Defence Ministry read: "The process of delivery takes place gradually, according to the development plan of a "magic wand", and is expected to continue for several weeks."
According to DefenseNews, the latest phase of development will involve the forces receiving multi-mission radar by Elta Systems, stunner interceptors by Rafael and its US partner, Raytheon Missile Systems, and the Golden Almond Battle Management Centre by Elbit Systems Elisra.
The next development phase will involve the integration all system components prior to a declaration of initial operational capability (IOC).
Also known as the 'Magic Wand', the DSWS surface-to-air missile system is designed to intercept medium-to-long-range rockets and cruise missiles, fired at ranges from 40km to 300km.
The system is said to be the future of Israel's aerial defence formation, and has been developed to work alongside Iron Dome, Patriot and Arrow missile systems.
DSWS incorporates its own interception management centre, in which operators can issue orders for interceptions of aerial threats.
Its missiles broadcast real-time sensory information, and it is expected to be linked to Home Front Command, which provides civilian projectile alerts and information to air defence systems.
