Israel has multi-layered air defenses against attacks by Iran, which has fired hundreds of ballistic missiles and suicide drones at Israel over the past two days as the Middle East rivals traded heavy blows.
Israel has been honing its air defenses since coming under Iraqi Scud salvoes in the 1991 War, in addition to receiving support from the US, which has provided its ally with advanced anti-missile equipment.
An Israeli military official said on Saturday that the defensive umbrella had an "80 or 90% success rate", but emphasized that no system is 100% perfect, meaning that some Iranian missiles were breaking through the shield.
Here are details of Israel's missile defenses:
ARROW
The long-range Arrow-2 and Arrow-3 interceptors, developed by Israel with an Iranian missile threat in mind, are designed to engage incoming targets both in and outside the atmosphere respectively. They operate at an altitude that allows for safe dispersal of any non-conventional warheads.
State-owned Israel Aerospace Industries is the project's main contractor while Boeing is involved in producing the interceptors.
DAVID'S SLING
The mid-range David's Sling system is designed to shoot down ballistic missiles fired from 100 km to 200 km (62-124 miles) away.
Developed and manufactured jointly by Israel's state-owned Rafael Advanced Defense Systems and RTX Corp, a US company previously known as Raytheon, David's Sling is also designed to intercept aircraft, drones and cruise missiles.
IRON DOME
The short-range Iron Dome air defense system was built to intercept the kind of rockets fired by Palestinian movement Hamas in Gaza.
Developed by Rafael Advanced Defense Systems with US backing, it became operational in 2011. Each truck-towed unit fires radar-guided missiles to blow up short-range threats such as rockets, mortars and drones in mid-air.
A naval version of the Iron Dome, to protect ships and sea-based assets, was deployed in 2017.
The system determines whether a rocket is on course to hit a populated area. If not, the rocket is ignored and allowed to land harmlessly.
Iron Dome was originally billed as providing city coverage against rockets with ranges of between 4 km and 70 km (2.5-43 miles), but experts say this has since been expanded.
US THAAD SYSTEM
The US military said last October that it had sent the advanced anti-missile system THAAD, or the Terminal High Altitude Area Defense system, to Israel.
THAAD is a critical part of the US military's air defenses and is designed to intercept and destroy short, medium and intermediate-range ballistic missile threats in their terminal phase of flight.
The US military helped to shoot down Iranian missiles fired at Israel on Friday, using ground-based systems, one US official said. A US Navy destroyer in the Eastern Mediterranean also helped to shoot down incoming ballistic missiles, Israeli media has reported.
AIR-TO-AIR DEFENSE
Israeli combat helicopters and fighter jets have fired air-to-air missiles to destroy drones that were heading to Israel, military officials have said.
Jordan’s air force also intercepted missiles and drones entering its airspace Friday, its state news agency said.

A Week Into the Fragile Israel-Iran Peace Agreement, Here's What We Still Don't Know

It's been a week since the United States pressed Israel and Iran into a truce, ending a bloody, 12-day conflict that had set the Middle East and globe on edge.

The fragile peace, brokered by the US the day after it dropped 30,000-pound "bunker-busting" bombs on three of Iran's key nuclear sites, is holding. But much remains unsettled, The Associated Press reported.

How badly Iran’s nuclear program was set back remains murky. The prospects of renewed US-Iran peace talks are up in the air. And whether US President Donald Trump can leverage the moment to get Israeli Prime Minister Benjamin Netanyahu 's government and Hamas focused on a ceasefire and hostage deal that brings about an end to the 20-month war in Gaza remains an open question.

Here is a look at what we still don't know:

How far Iran's nuclear program has been set back Trump says three targets hit by American strikes were “obliterated.” His defense secretary said they were “destroyed.”

A preliminary report issued by the US Defense Intelligence Agency, meanwhile, said the strikes did significant damage to the Fordo, Natanz and Isfahan sites, but did not totally destroy the facilities.

Rafael Grossi, head of the International Atomic Energy Agency, said on CBS’ “Face the Nation” on Sunday that the three Iranian sites with “capabilities in terms of treatment, conversion and enrichment of uranium have been destroyed to an important degree.” But, he added, “some is still standing” and that because capabilities remain, “if they so wish, they will be able to start doing this again.” He said assessing the full damage comes down to Iran allowing inspectors access.

What future US-Iran relations might look like

After the ceasefire deal came together, Trump spoke of potentially easing decades of biting sanctions on Tehran and predicted that Iran could become a “great trading nation” if it pulled back once-and-for-all from its nuclear program.

The talk of harmony didn't last long.

Ali Khamenei, in his first public appearance after the ceasefire was announced, claimed Tehran had delivered a “slap to America’s face." Trump responded by suggesting the supreme leader own up to the fact Iran “got beat to hell. The president also said he was backing off reviewing any immediate sanction relief, because of Khamenei's heated comments.

White House officials say the US and Iran are already in early discussions about resuming negotiations that had ended after Israel began launching strikes. But Iranian Foreign Minister Abbas Araghchi says there's no agreement in place to restart talks.

It's unclear if Iran's leadership is ready to come to the table so soon after the fighting has ended — especially if Trump holds to the position that Iran must give up nuclear enrichment for even civilian use. And Trump has offered conflicting statements about his commitment to talks. “We may sign an agreement,” he said Wednesday at a NATO summit press conference. He added, “I don’t think it’s that necessary.”

What role Iran's supreme leader will play

Khamenei's age and recent diminished appearance have raised questions about the scope of his involvement in US-Iran relations and Iran's response to both American and Israeli strikes. But despite having spent the last few weeks in a bunker as threats to his life escalated, there is little indication that Khamenei does not still reign supreme over the country's massive military and governmental operations.

Khamenei has ruled three times longer than his predecessor, the late Ruhollah Khomeini, and has shaped life for the country's more than 90 million people perhaps even more dramatically.

He entrenched the system of rule by the “mullahs,” or Shiite Muslim clerics. That secured his place in the eyes of hard-liners as the unquestionable authority, below only that of God. At the same time, Khamenei built the paramilitary Revolutionary Guard into the dominant force in Iran’s military and internal politics.

How Iran might strike back Iran's retaliatory missile attacks on a US base in Qatar following the American bombardment were sloughed off by the White House as a half-hearted, face-saving measure. The US was forewarned and the salvos were easily fended off.

Yet Iran remains a persistent threat, particularly via cyberwarfare. Hackers backing Tehran have already targeted US banks, defense contractors and oil industry companies — but so far have not caused widespread disruptions to critical infrastructure or the economy.

The US Department of Homeland Security last week issued a public bulletin warning of increased Iranian cyber threats. And the US Cybersecurity and Infrastructure Security Agency, is urging organizations that operate critical infrastructure like water systems, pipelines or power plants to stay vigilant.

Whether the Israel-Iran ceasefire will hold It remains a fragile peace.

Immediately following the US strikes, Trump got on the phone with Netanyahu and told the Israeli leader not to expect further US offensive military action, according to a senior White House official who was not authorized to comment publicly about the sensitive diplomatic talks.

But even as he agreed to deal, Netanyahu made clear that Israel will strike again “if anyone in Iran tries to revive this project.”

The ceasefire deal came without any agreement from Tehran on dismantling its nuclear program. Khamenei claims the attacks “did nothing significant” to Iran's nuclear facilities.

Trump expressed confidence that Iran, at the moment, has no interest in getting its nuclear program back up. “The last thing they’re thinking about right now is enriched uranium,” Trump said.

Still, Trump says he expects Iran to open itself to international inspection to verify that it doesn’t restart its nuclear program by the International Atomic Energy Agency, the UN nuclear watchdog, or some other organization "that we respect, including ourselves.”

Whether Trump can now press Netanyahu on Gaza

The president took a big gamble with his decision to order strikes on Iran's nuclear fortress.

As a candidate, he promised to quickly end Russia's brutal war in Ukraine and the Israel-Hamas conflict in Gaza, but has failed to find a resolution to either. He also vowed to keep the US military out of foreign conflicts.

But after helping Israel with US strikes on Iran, Trump — in conversations with Netanyahu and other world leaders in recent days — has made clear he wants a deal completed soon, according to two people familiar with the private discussions and were not authorized to comment publicly.

On Friday, Trump told reporters, “We think within the next week we’re going to get a ceasefire.”

Trump didn't offer any further explanation for his optimism. But Israeli Minister for Strategic Affairs Ron Dermer is expected to be in Washington this week for talks on a Gaza ceasefire, Iran and other matters, according to an official familiar with the matter. The official spoke on condition of anonymity because they were not authorized to speak to the media.
