Israel's defense ministry says the country's newest missile defense system has been successfully tested.

The "David's Sling" system is designed to stop mid-range missiles and makes up the final leg of what Israel calls its "multilayer missile defense."

The ministry said the system detected and destroyed a test ballistic missile Wednesday. It said this marked a "step forward" toward deployment next year.

"David's Sling," also known as "Magic Wand," is designed to intercept projectiles with ranges between 70 kilometers (45 miles) and 300 kilometers (180 miles). That would include countering the large arsenal of Hezbollah rockets in Lebanon and those of President Bashar Assad's government in Syria.

Israel also has deployed Arrow system for longer-range threats from Iran and the Iron Dome system against short-range rockets from the Gaza Strip.
