How Israel Defended Itself Against Iran’s Missile Attacks

On Oct. 1, Iran fired almost 200 ballistic missiles, but Israel sheltered under a highly complex range of missile defense systems.

Iran fired 181 long-range ballistic missiles at Israel on Oct. 1, with each missile capable of killing dozens in a single strike. But, according to Rear Adm. Daniel Hagari, spokesman for the Israel Defense Forces, after the millions of Israelis emerged from the air raid shelters where they had hunkered down, he was not aware of a single reported casualty.

How? The answer lies in Israel’s multi-layered missile defense system, built with the assistance of the United States.

Tim Ripley, a military analyst and editor of the Defence Eye website, said Israel’s different missile defense systems come under the umbrella of a single structure.

He told The Epoch Times: “The key thing is that all these different systems are integrated into a coherent network. They recognize that no one system has everything covered.”

Ripley said ballistic missiles go into space before dropping down. The first line of defense—known as the Arrow system—fires missiles that intercept the ballistic missiles at the tops of their trajectories. Then the next layer—David’s Sling—targets the missiles in “mid-atmosphere.” Those that make it past that layer are intercepted by the Iron Dome system, more commonly known for shooting down rockets fired by the Hezbollah and Hamas terror groups.

He said the overriding structure relies on artificial intelligence (AI)-driven algorithms.

“These AI-driven algorithms work out the trajectories of these missiles, estimate where they’re going to land, and then allocate specific batteries of missiles to intercept them with the best chance. So, it’s very advanced AI algorithms that process all this information, particularly if you’ve got 100 missiles in the air at once,” Ripley told The Epoch Times.

He pointed out a key difference between Israel and Ukraine.

“The Ukrainians don’t have as big an air defense network, they don’t have as many missiles to fight back with, and stuff gets through,” Ripley said.

According to the Pentagon, the U.S. Navy also assisted the Israelis in shooting down some of the missiles, and the United States and some other allies were able to plug into the Israeli system.

So what are Israel’s missile defense systems?

Iron Dome

Iron Dome, which was developed by Israel with U.S. support, is the most well known of the systems.

It specializes in shooting down projectiles fired at short range and has been used countless times to defend against Hamas rockets fired from the Gaza strip and Hezbollah attacks from southern Lebanon.

It has intercepted thousands of rockets, and Israel says it has a success rate of more than 90 percent.

But it has a limited range of about 45 miles.

David’s Sling

Named after the biblical figure’s famous weapon, which killed the giant Goliath, David’s Sling is a rocket system designed to intercept medium-range missiles.

David’s Sling fires interceptors, known as the Stunner or SkyCeptor, at incoming missiles. Each interceptor is worth at least $1 million.

It was also developed with assistance from the United States.

David’s Sling has been used mainly to bring down Hezbollah rockets fired from southern Lebanon and aimed at Jerusalem or Tel Aviv, a distance of about 100 miles. It has a range of up to 185 miles.

The Arrow

The Arrow system was designed to intercept long-range ballistic missiles, such as those that were fired at Israel by Iran on Oct. 1.

The newest iteration, Arrow 3, has a range of 1,490 miles and has also been used to take down missiles fired by the pro-Iran Houthi rebels in Yemen.

Only missiles fired from eastern Iran are beyond its range.

On April 13, 2024, Arrow 3 was used to great effect during what Iran called Operation True Promise.

The Iranians fired 120 missiles, 170 drones, and 30 cruise missiles at Israel in retaliation for the Israeli bombing of their embassy in Damascus.

Israel said the attack was successfully thwarted, with 99 percent of the missiles and drones shot down and no casualties.
However, an Institute for the Study of War article published in April pointed out a potential benefit for Iran. “The attack probably helped Iran identify the relative strengths and the weaknesses of the Israeli air defense system,” it stated.

“The only Iranian missiles that got through hit an Israeli military base, limiting the damage, but a future strike in which several ballistic missiles penetrate Israeli air defenses and hit Tel Aviv or Haifa could cause significant civilian casualties and damage to civilian infrastructure, including ports and energy.”

Patriot

The oldest layer of missile defense is the Patriot system, which was first used in 1991 to intercept Scud missiles that were fired by Iraq’s then-leader, Saddam Hussein, during the first Gulf War.
Nowadays, it’s also used to shoot down drones, but it could also intercept planes, should the Iranian air force attack Israel.

Iron Beam

Israel is constantly developing new systems, with U.S. funding and technical support, to intercept emerging threats.

The newest system, which is still in development, is called Iron Beam and, as its name suggests, is based on laser beam technology.

According to Israel, the high-energy laser weapon will be a game changer, as well as much cheaper to operate.

Rafael, the Israeli firm that is building Iron Beam, states on its website: “It quickly and effectively engages and neutralizes a wide array of threats from a range of hundreds of meters to several kilometers. Engaging at the speed of light, Iron Beam has an unlimited magazine, with almost zero cost per interception, and causes minimal collateral damage.”
In 2022, The Times of Israel reported that Lockheed Martin had signed a deal with Rafael to develop Iron Beam.

Lockheed Martin Chief Operating Officer Frank St. John was quoted as saying, “This unique capability will enhance Israel’s vital air and missile defense system with state-of-the-art laser technology, and we are honored by the opportunity to expand Lockheed Martin’s role as a security teammate for the state of Israel.”

A promotional video by Rafael on YouTube shows a live field test that it says was carried out in March 2022.
In August, The Jerusalem Post said Rafael CEO Yoav Tourgeman was hoping that Iron Beam would become operational in 2025.
