How Missile Defense Works (and Why It Fails)


Once a ballistic missile is fired in the air, a defender has only a few minutes to identify his precise trajectory and try to shoot him.

The target, An enemy warheadis inside an object the size of a car which usually flies through the edge of the space several times the speed of the sound.

Since Friday, Iran has drawn a barrage of ballistic missiles to targets through Israel, a reprisals for a devastating surprise attack that the Israeli government has launched against Iranian nuclear and military sites.


The most advanced anti -missile defense systems in the world, deployed by Israel and the United States, have stopped some of the missiles – but not all. Strikes, like these, the Israeli of Iran, have killed civilians, according to officials from the two countries.


This is why stopping a ballistic missile attack is so difficult.

Ballistic missiles like those pulled by Iran escape the atmosphere and accelerate high speeds while falling on earth. Just about Iranian missiles to reach Israel, analysts believe. There is much less time to make critical decisions about how to stop them.

In a few seconds, satellite Must detect the thermal signature released by a missile launch. Radars Must find the missile and try to calculate its exact course.

A defensive missile called a interceptor Must be dismissed shortly after reaching the missile in time.

It’s pretty hard with a missile. But Iran fired A large volley of them. The objective seems to be to overwhelm the Israeli defenses.


Radars can only follow so many targets at a time, and launchers, once emptied, may need half an hour or more to recharge.

Beyond that, if they are concerned about future attacks, targeted countries may also need to make a critical decision to the fraction Reserve precious interceptors Only for incoming missiles that seem likely to do the most damage.

The best known defense system in Israel, the Iron Dome, was built to stop Short -range RocketsAnd is too slow and limited with regard to ballistic missiles. For this, Israel relies on several more advanced defense layers designed to counter the ballistic missiles at different flight stages.

The most advanced systems, long -range interceptors such as arrow 3, work in space, where ballistic missiles like these drawn Iran spend most of their time. They are the first chance to stop a missile, but above the atmosphere, there is no room for error.

Both a interceptor and a enemy missile Lose the boosters that feed them in space. There are only two small vehicles left, rushing to each other.

The interceptor seeks A direct blow To destroy the warhead. At home, the interceptor carries sensors to follow the enemy missile and propellants to move to him. But when a interceptor detects his target to a distance mile, he has only a fraction of a second to adapt.

This is because missiles like the last Iran Three feet wide At the base when they are in space, and they travel about two miles every second.

If it was not difficult enough, some ballistic missiles carry lure To deceive the interceptor. Booster debris remains can also confuse it.

We do not know how often interceptions above the atmosphere actually work. Governments tend to avoid disclosing specific interception rates, and they have every reason for present a positive imageEven when interceptions fail. The same goes for companies that make expensive systems.

When combined with American anti -missile systems in the region, Israel currently has the most anti -missile defense layers in the world. If the external layer defenses fail to stop a missile, short -term systems that intercept the missiles closer to the ground can have another chance.

But time is running out quickly. The closer a ballistic missile, the more dangerous it becomes. And even if a low -altitude interception is successful, the resulting debris can always be fatal.

If a missile succeeds in entering the atmosphere, it often remains less than a minute before it strikes.


Defenses that work in the high atmosphere – like Israel’s arrow 2 or the Thaad system that the United States recently sent to Israel – must dismiss its interceptors in a few seconds.

While the missile is approaching the ground, nearby defenses As the Patriot system in the United States gives a last chance to stop it. But these systems have a range of around 12 miles and can only protect from limited areas.

An attacker can rely on a variety of tactics. To distract the enemy, he can draw a cheaper volley Timed weapons to arrive at the same time like ballistic missiles. This is what Iran tried during its attack in April, but Israel and its allies seem to have been able to sort between faster and slower weapons, using other defenses such as fighter planes to counter them.

Last year, Iran also pulled large missile dams in Israel, but left limited damage. When Israel and Iran clashed last year, they fought in short and contained bursts which generally ended in a few hours, and the two parties looked for ramps out of ramps which allowed tensions to reflige.

But this time, the two countries have incitement To stop and without obvious route to the pure and simple victory.

During a prolonged conflict, it could become a question of which team first lacks missiles.
