A sophisticated anti-missile system successfully completed its second round of testing today in Israel.

David’s Sling was tested against a short-range ballistic missile Wednesday in southern Israel. The drill was conducted by the Israel Missile Defense Organization with help from the US Missile Defense Agency.

The US has spent considerable time and money to help develop the system, which is designed to work in conjunction with Israel’s Iron Dome defense batteries and the Arrow 2 system.

David’s Sling can shoot down rockets with a range between 60 to 125 miles, considered mid-level range. The Iron Dome focuses on short-range missiles, while the Arrow 2 combats long range.

Israel’s Defense Department said the new system is “designed as an additional layer of defense against ballistic missiles, to add interception opportunities to the joint US-Israel Arrow Weapon System and to improve the active defense architecture of the State of Israel against missile threats.”

The test came as Israel stands off with the US on a proposed easing of sanctions on Iran in return for reduced uranium enrichment. The Jewish state has said it will not abide by such a deal, and will take solo military action if need be.

“The successful test is a major milestone in the development of the David’s Sling Weapon System and provides confidence in future Israeli capabilities to defeat the developing ballistic missile threat,” the statement said.

David’s Sling is built by Israel’s Rafael Advanced Defense Systems with the US’s Raytheon Co.
