Israel warns Iron Dome still at experimental stage

The Guardian, amongst many others (including BBC News, three days ago), has the story - with a video:
The initial success of Israel's Iron Dome missile-defence system has been hailed as an example of "Jewish genius" – but the army insists it is still at an experimental stage. Since 7 April the system has shot down nine rockets fired at Israel from Gaza, although it was unable to stop at least 11 others.

Boaz Ganor, the director of the Institute for Counter-Terrorism said: "It's a technical revolution that shows us what may be possible in the future. The success has been limited by the fact that we only have two batteries, but it has proven itself accurate and efficient."

The Iron Dome consists of three units: a missile-tracking radar, a control centre and a missile-firing unit. The moment a rocket is launched its trajectory is relayed to the control centre, which decides whether it will land in an open or built-up area. If the rocket threatens a densely populated area a missile is fired at it.

The world first became aware of the possibilities of missile defence during the Gulf war in 1991. US Patriot missile batteries in Israel and Saudi Arabia appeared to be successful at eliminating scud missiles fired by Iraq. In fact, the system was far less effective than it appeared and subsequent analysis estimated it had a success rate of about only 10%.

During the Iraq war in 2003 the improved Patriots proved more successful against allied aircraft than long-range rockets. Iraq did not fire any long-range rockets and the Patriots downed one British jet and one American jet, killing both crews.

Israel has long been the target of short-range rockets such as the Russian-designed Katyusha, supplied to Palestinian groups in Jordan and Lebanon in the 1970s and 80s. More recently, Hezbollah fired some 4,000 rockets at Israel in the 2006 Lebanon war, killing 44 people.

Israel has developed the Arrow long-range missile-defence system but, after its experience in 2006, the government decided to invest in the Iron Dome system instead. The cost of its development and deployment is estimated at more than £1bn, some of which will be subsidised by the US.

Critics point out that each Iron Dome missile costs about £25,000, while the rockets they eliminate are worth less than a few hundred, which could allow militants to wage economic warfare against Israel. Others suggest it would be easy to fool missile-defence systems with decoys.

"We know that terrorists are elusive and on a learning curve. There is no doubt that this success will challenge them to rethink and fine tune their tactics," said Ganor, "The whole idea of launching rockets at Israel was a response to the failure of other tactics. If Iron Dome proves to be successful, Hamas and Hezbollah will certainly try to think of new methods of attack."
