  • Israel has one of the most advanced air defense systems.

  • In January, Israeli officials amended its 2024 budget to allocate $15 billion more in war spending.

  • Its air defenses are being tested amid its war against Hamas and Iran's retaliatory attacks.

Israel has some of the most advanced air defenses in the world, systems that have defended its troops and citizens from rocket and missile barrages.

Air defenses are essential to Israel's security. Much of its population is within reach of rockets and missiles fired by Hamas and Hezbollah, as well as the ballistic missiles fired by Yemen's Houthis. Israel, with some help from the US, managed to intercept 99% of the drones Iran fired during its retaliatory attacks on April 13.

Earlier this year, Israeli officials amended its 2024 budget to allocate $15 billion more in war spending as Israel's war in Gaza stretches the country's budget and tensions rise throughout the region.

About 15% of Israel's defense budget comes from the US. Since its founding in 1948, the US has sent Israel about $300 billion in economic and military aid, making it the largest cumulative recipient of US foreign aid.

Nearly all of the aid the US has sent in recent months has been allocated to its advanced defense systems and military equipment. But America's involvement in Israel's war on the Gaza Strip has grown controversial. The US is providing limited humanitarian aid to Palestinians in Gaza while also providing military support and weapons to Israel.

More than 30,000 Palestinians have died since October 7, 2023, according to the Ministry of Health in Gaza.

The most well-known of Israel's air-defense system, the Iron Dome consists of a network of radar detectors and missile launchers used to intercept enemy fire, including short-range rockets and artillery.

Deployed in southern Israel in 2011 following the war between Israel and Hezbollah, the US helped and funded the development of the short-range rocket defense system. It contributed at least $1.6 billion to the Iron Dome system from 2011 to 2021, as well as another $1 billion in 2022.

The first layer of defense

The Israel Defense Forces said the objective of the Iron Dome is to "protect Israeli civilians from the constant threat of rockets by intercepting them." The IDF described the Iron Dome with three adjectives: "accuracy, speed, and capacity."

Armed with Tamir interceptor missiles, the multi-mission defense system can shoot down enemy rockets and artillery up to 43.5 miles away. The advanced missile system has a radar station that detects and tracks the course of enemy rockets before launching a missile to intercept it. The missiles track their target with electro-optical sensors and detonate in the air when close.

While the Iron Dome doesn't have a perfect interception record, it has blocked a majority of enemy fire in Israeli airspace, especially at times of intense barrages from Hamas militants.

But the Iron Dome is just one layer of what is considered one of the most advanced air defense systems in the world.

Missiles are much longer range than shells, but they have the disadvantage of also being expensive. The Tamir missiles fired by Iron Dome are estimated to each cost around $50,000.

David's Sling

The middle layer of Israel's Iron Dome defense system is David's Sling, a medium- to long-range air defense system designed to intercept rockets fired from up to 185 miles.

Also known as the Magic Wand, the versatile missile system carries up to 12 interceptors. Its command and control center, known as the Golden Almond, provides threat assessment and plans and controls interception, complemented by the system's multi-mission radar used to detect and track airborne threats.

Developed in collaboration with the US and Israel, David's Sling is "a central factor in Israel's multi-tiered defense array," according to Israel's Ministry of Defense, supporting other layers of its air defense system by "tackling large-caliber rockets, short-range ballistic missiles," and other types of enemy fire.

The top layer of Israel's sophisticated air defense system is Arrow-3, capable of engaging targets at longer ranges and higher altitudes, as well as more precisely intercepting ballistic missiles.

Arrow-3 interceptor operates with the Arrow Weapon System, the world's first operational, national, stand-alone anti-tactical ballistic missile defense system, according to Israel Aerospace Industries, the primary contractor for the AWS. The system was developed in partnership with Boeing and significant funding from the United States.

Arrow-3 works in conjunction with its predecessor, Arrow-2, to intercept ballistic missiles and other warheads using a two-stage interceptor.

Arrow-3's "interceptor is a world-class missile that, together with the Arrow-2, significantly expands the State of Israel's defense capabilities," according to Israel's Ministry of Defense.

In November 2023, Israel confirmed the first operational use of the Arrow-3 to stop an inbound enemy missile launched by Houthi militants from Yemen, marking the first time all three layers of Israel's aerial defense were working simultaneously.

"All of these provide protection in every layer of aerial defense and enable optimal protection of the Israeli home front," the IDF said in a statement at the time.

Israel also deployed Arrow 3 to intercept the drones and missiles Iran fired during its retaliatory attacks on April 13.

Israel's chief military spokesman Rear Adm. Daniel Hagari, told reporters on April 14 that Arrow 3 had "proved itself against a significant number of ballistic missiles" fired by Iran.

"IAI's engineers have been working for years to deal with the varied threats against the State of Israel. They have reached a degree of excellence reflected in the results we saw tonight, and this with the full support and cooperation of Israel's Ministry of Defense and the IDF. We are proud to contribute to maintaining Israel's security against any threat, however complex it may be," Boaz Levy, the president and CEO of Arrow's primary contractor, Israel Aerospace Industries, told Business Insider in an emailed statement.

Israel's air defense system isn't just limited to land. The country also has a naval version of its Iron Dome system, mounting it aboard Israeli missile boats.

The naval version of the aerial defense system, known as C-Dome, is deployed aboard Sa'ar 6-class corvettes, four German-made warships ordered for Israel's navy.

In addition to the C-Dome, Sa'ar 6 vessels are also equipped with a 76mm Oto Melara Super Rapid main gun that's effective against close aerial threats.

After two years of development, Israel's military announced Monday that the seaborne defense system was used for the first time to intercept a "suspicious aerial target" that entered Israeli airspace near the city of Eilat, which has been frequently targeted by Houthis in Yemen in support of Hamas.

"Overnight, for the first time ever, an IDF Sa'ar 6-class corvette missile ship successfully intercepted a UAV (unmanned aerial vehicle) that had approached from the east and had crossed into the area of the Gulf of Eilat," the IDF said.

The Israeli naval fleet also includes 11 other warships in addition to the four Sa'ar 6-class corvettes, as well as five Dolphin-class submarines.

To further bolster its air defenses, Israel is also looking at a new "all-in-one" surface-to-air missile system called SPYDER, manufactured by Israeli defense company Rafael Advanced Defense Systems.

Israel, in collaboration with Rafael, is testing a new configuration for the weapons system, taking the missile launcher, radar, command and control system, and technology for surveillance and target acquisition and fitting it to an eight-wheel drive vehicle.

"Developed to address the critical operational needs of the modern battlefield, the SPYDER AiO provides an agile, autonomous, air defense asset, capable of rapid deployment within minutes, in challenging terrains, and with short reaction times," according to a fact sheet from Rafael.

Designed to carry up to eight canisterised missiles, including I-Derby SR, I-Derby ER, and Python-5 SR, it can engage up to four targets at a time, with a maximum range of up to 24.8 miles and an altitude of up to 7.4 miles, according to the fact sheet.

In January, Israel's defense ministry announced a successful test run of the new weapons system configuration, which is capable of intercepting drones, aircraft, cruise and ballistic missiles, and precision-guided munitions.
