Israeli army is prepare to take delivery of first Rafael David's Sling anti-missile system 2906134.

Iron Dome, heavily funded by the United States, became operational in early 2011.

The fifth and sixth batteries received by the air force, which has control of all air defenses, are improved versions of a system that currently has a kill rate of around 85 percent of those rockets it engages. The sixth battery is expected to be deployed within two months, and could be delivered as early as July.

David's Sling, being developed by Rafael and the Raytheon Co. of the United States, was unveiled at the Paris Air Show this month. Until then, all that Israelis been seen of it was a brief video of a secret test in the Negev Desert of southern Israel in November 2012.

Also known as Magic Wand, David's Sling is designed to intercept medium-range missiles at a range of 100 miles.

It's the next layer in the shield above Iron Dome and underwent its first test-flight in February. It's scheduled to become operational in 2014. Each missile costs $1 million.

The primary function of the road-mobile David's Sling system in Israel's current threat environment is to counter the medium-range missiles like the Fateh-100s that Hezbollah now has in considerable numbers north of Israel and which can reach pretty much anywhere inside the Jewish state, including all its cities and major towns.

David's Sling will be able to backstop the two Arrow variants against ballistic and cruise missiles that get past them. It can cover all of Israel from a small number of launch sites around the country.
