Israel revamps air defences
Changes are to systems that protect against missiles and rockets.
ARIEH O’SULLIVAN THE MEDIA LINE
Even before the recent upheaval in the Arab world, Israel began implementing a major overhaul of its air defences, which have been rushed to the field with newly designed anti-rocket batteries backed up by an integrated central control centre to better protect the home front.
“We are the pioneers in the world in this field,” said Brig.-Gen. Doron Gavish, the officer who first fired missiles against incoming rockets in the 1991 Gulf War when
Saddam Hussein lobbed Scuds on Tel Aviv.
After he took over the Israeli air force’s anti-aircraft corps, he changed its name to the Air Defence Forces and brought in a new unit insignia. More importantly, under his command, the Air Defence Forces have been revamped with higher quality manpower and reorganized to deal with what is arguably the greatest threat to Israel – incoming rockets and missiles.
“Unfortunately, we’ve had to develop capabilities against those threats and under those circumstances I can say that, yes, we are a kind of pioneer because we have to deal with it,” Gavish said in an interview. “We have to develop systems very, very fast. We have to develop our doctrines and technologies in order to deal with the threats of rockets and missiles against our civilians.”
Israel’s enemies long ago learned they would not achieve strategic parity in the conventional battlefield. Their Soviet-equipped divisions and squadrons were no match for Israeli armored columns and its top-of-the-line air force. In the 1980s, Israel’s foes began investing in surface-to-surface missiles to bypass its frontlines and take the war to the rear.
“Israel had wars of luxury where the battles were fought without a threat on the home front, but that all changed in 1991” when Iraq’s Saddam Hussein fired 39 Scud missiles on Tel Aviv and Haifa, said Home Front Defence Minister Matan Vilnai at an international aerospace conference in Jerusalem last month.
Israel is arguably the state with the most missiles pointed at it. The Lebanese movement Hezbollah alone is said to have some 40,000 rockets in their arsenal. Early on Nov. 29, a number of Katyusha rockets landed in northwestern Israel, which were fired from areas controlled by Hezbollah in southern Lebanon. While no group claimed responsibility and residents were not ordered into bomb shelters, it showed how volatile the region could be.
Israel’s air defence network is one of the densest in the world. Not only are all aircraft in the region monitored but every drone, rocket and missile launch is detected and monitored from as close as the Gaza Strip to as distant as Iran, some 1,300 kilometres away.
Gavish said the advances in missile defence have revolutionized Israel’s security doctrine. He said that, since the state’s inception in 1948, its security doctrine has rested on three pillars: early warning, subjugation and deterrence. The innovations of the past 10 years have added “defence” as another pillar.
The anti-aircraft arm of the air force – which last shot down an enemy aircraft during the 1982 Lebanon War – was tasked with downing rockets and missiles too and began integrating first the U.S.-made Patriot, then PAC-2 batteries, anti-aircraft missiles refigured to shoot down mid-range missiles. Later, it deployed the Israeli-designed and -built Arrow batteries aimed at shooting down long-range ballistic missiles. New batteries such as the David’s Sling and the Magic Wand are being developed to flesh out its multi-layered missile and rocket defences.
“What has been happening in the past few years is that missions that were not part of our classic mission became part of our mission. One of them is the alert. We are now in a phase where we can give a better alert to our civilians. There are all kinds of radars and sensors which are deployed all around Israel and this way we can give better alert and save lives,” Gavish said. “And the other mission is to intercept rockets and missiles.”
With no answer for the short-range rockets like Grad, Katyushas and Qassams fired by the Hezbollah in Lebanon or the Palestinian Hamas movement in the Gaza Strip, Israel began designing its own system, called the Iron Dome. Because of the nature of the conflict and the intimacy between the defence and defence industry establishments, weapons development is unusually swift in Israel. Gavish said the first Iron Dome batteries were actually fielded a year ahead of schedule.
The air force recently integrated a national Ballistic Picture Control Centre (BPCC) in order to enhance its early warning capabilities. In March, two Iron Dome batteries were rushed into field operation before the system had completed its final development to meet an escalation of tensions along the border with the Hamas-controlled Gaza Strip. In April, the batteries successfully intercepted eight out of nine Grad-type rockets fired at Israeli cities. In a flare up in October, Iron Dome batteries intercepted four more rockets.
“I can say that, in the last year, in the three rounds of escalation that, unfortunately, we saw in the southern part of Israel, we intercepted a big number of rockets which were launched on the southern cities of Israel,” Gavish reported.
Each Iron Dome battery costs some $80 million. A senior officer said Israel is planning to procure another six to 11 batteries so that the entire area under missile threat is covered. A top Israeli defence official was quoted as saying that the Ministry of Defence planned to invest $1 billion for development and manufacturing of Iron Dome defences. This reportedly includes a U.S. grant of $205 million. Interceptors are costly, too, at about $1 million each, which has led to a search for cheaper defensive shields.
Michael Rinn, vice-president of Directed Energy Systems at the U.S. aerospace company Boeing, said it is developing high-energy laser to destroy small rockets, mortar and artillery rounds.
“A system like this complements kinetic systems like the Iron Dome,” Rinn explained. “A system that runs off an electrical generator power runs and runs and runs, so you don’t run out of rockets. It continues to run. If you let your imagination go, you can see that these kinds of systems which are just starting to hit the test ranges could be so important for a country like this which has a constant threat.”
Gavish said that cooperation with the United States was extremely important in fostering interoperability necessary for future cooperation against missile threats. “We are working very close with U.S. forces and hold a series of exercises named Juniper Cobra every two years. The next one will be next year and this is the biggest exercise in the world for active defence. We see interoperability as a very important issue and, obviously, we see the United States as our strategic ally and friends and working with them is always a learning experience for us and obviously enhances our capabilities here in Israel.”
Meanwhile, Israel’s PAC-2 radars were recently shipped to the United States for upgrade. The process is reportedly expected to cost some $15 million, which is to be paid for out of the $3 billion in annual U.S. military aid. In the interim, Germany, which loaned Israel two PAC-2 batteries in 2003 prior to the U.S. invasion of Iraq, shipped another PAC-2 radar to the Israeli air force for free while the older ones are being refurbished, Defence News reported.
