Israeli and US defence officials on Wednesday successfully carried out a second intercept test of a new system against short-range missiles.
"The Israel Missile Defence Organisation and the US Missile Defence Agency completed a successful intercept test of the David's Sling Weapon System (DSWS) against a short-range ballistic missile today," it said in a statement.
"This is the second intercept test of the Stunner interceptor for the DSWS. The intercept test was conducted at a test range in southern Israel," it said, without specifying where.
The first such test took place in November 2012, days after a truce brought an end to eight days of fighting between Israel and Palestinian militants in Gaza during which over 1,000 rockets were fired at the Jewish state, many of which were intercepted by the Iron Dome short-range defence system.
"The DSWS is designed as an additional layer of defence against ballistic missiles, to add interception opportunities to the joint US-Israel Arrow Weapon System and to improve the active defence architecture of the State of Israel against missile threats," the defence ministry said.
The Arrow, a cutting-edge system designed to counter long-range missiles, has successfully intercepted missiles comparable to Iran's Shihab-3 in a variety of test conditions.
David's Sling, which Israeli television said is designed to intercept missiles fired from a distance of 50 to 250 kilometres (30 to 155 miles), is meant to bridge the gap between Arrow and Iron Dome.
Expected to be ready for deployment in 2014, it is being developed by Israel's Rafael Advanced Defence Systems and US company Raytheon.

Israel to Deploy Sixth Iron Dome, Awaits David's Sling
Israel is all set to deploy its sixth Iron Dome counter-rocket battery, produced by Rafael Advanced Defense Systems, and is preparing to take delivery of the first unit of David's Sling, another Rafael anti-missile system.
The fifth and sixth batteries received by the Israel 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.
The new Iron Dome battery, intended to shoot down short-range missiles, has been upgraded and its range extended. That means the system, the only combat-tested weapon in the multilayered anti-missile shield Israel is building, can intercept hostile rockets earlier in their trajectory and minimize damage and casualties.
Iron Dome, funded by the United States, became operational in early 2011.
The Israel’s local daily reported that two further batteries could be deployed by January 2014.
Military planners have said they need 20 Iron Dome batteries to cover all of Israel, although the new-model systems, which can cover wider areas than the earlier variants and intercept multiple targets coming from different directions, may mean that fewer batteries will be required.
Israel's Defense Ministry, hit by budgetary cuts, has had to turn to U.S. for funds to buy the batteries, which cost more than $50 million per piece.
The Pentagon's Missile Defense Agency included $220 million in its annual budget in March for Israel to buy more Iron Dome batteries in fiscal 2014. That was the first time the MDA had specifically sought funds for Iron Dome, underlining the U.S. Defense Department's commitment to maintain military aid for Israel, outside the $3.1 billion it gets every year, despite major cuts in U.S. defense spending.
The U.S. House of Representatives Armed Services Committee approved a $284 million funding increase June 6 for Israel's anti-missile shield, including an additional $15 million for the Iron Dome program.
The United States provided $205 million in 2011 for the Israeli Air Force to buy the first four Iron Dome batteries.
Iron Dome is the bottom tier of the four-level anti-missile shield the Israelis call "Homa," the wall, which will protect the tiny Mediterranean state against the short-range Grads, the longer range Iranian-built Zelzals and Fateh-110s possess by Hezbollah and Iran's strategic Shehab-3 intermediate-range ballistic missiles -- with more advanced Sejjil-2 weapons in the pipeline -- and Syria's Scud-D weapons.
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 termed 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.
After these comes Arrow-2, developed by state-owned Israel Aerospace Industries. The $1 billion program was heavily financed by the U.S. Two Arrow-2 batteries are known to have been deployed to intercept ballistic missiles at high altitude and long range.
A more advanced variant, Arrow-3, is currently being developed by IAI and the Boeing Co. of the United States. It will be more powerful, capable of intercepting missiles at altitudes of 70 miles or more outside Earth's atmosphere earlier in their trajectories than Arrow-2.
The primary function of the road-mobile David's Sling system in Israel's current threat environment is to counter the medium-range missiles.
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.
