What is THAAD? An overview of the anti-missile system and its significance

The Terminal High Altitude Area Defense ( THAAD ) is an advanced missile defence system developed by the U.S. to intercept and destroy short, medium, and intermediate-range ballistic missiles during their terminal phase (the last phase of their flight). Unlike other missile defence systems, THAAD doesn’t use explosives to neutralise threats. Instead, it relies on the "hit-to-kill" technique, where it physically collides with incoming missiles to destroy them through impact. This system was developed in response to the Scud missile threat identified during the Gulf War in 1991 and has been operational since its first deployment in May 2008.


How does THAAD work?

Unlike traditional defence systems that use explosive warheads, THAAD uses a "hit-to-kill" approach. This means it doesn't explode to destroy enemy missiles. Instead, it uses the sheer force of impact (kinetic energy) by directly colliding with incoming missiles. This method allows for more precise destruction without creating additional explosive damage.


Why was THAAD created?

THAAD was developed as a response to the threat posed by Scud missiles, which were a significant danger during the Gulf War in 1991. It was created to defend against ballistic missile threats that could target civilian or military sites.


Operational range

THAAD can destroy incoming missiles at high altitudes (up to 93 miles or 150 km) and over long distances (up to 125 miles or 200 km), making it effective against various types of missile threats.


System components

• Interceptor missiles: These missiles are launched to intercept and destroy the threat.
• Mobile launch vehicles: These vehicles carry the interceptor missiles and can be moved to different locations.
• Radar systems: These track and detect missile threats from far away (up to 3,000 km), allowing for early warning.
• Fire control system: This coordinates the launch and targeting of interceptors, ensuring the missiles hit their targets.

THAAD: Recent developments

The U.S. recently decided to deploy a THAAD system to Israel , along with 100 military personnel, after Iran launched a massive missile attack against Israeli territory. Almost 200 ballistic missiles were fired, highlighting the need for enhanced missile defence in the region. This deployment is part of the U.S.'s ongoing support for Israel, reinforcing its defence against potential threats from Iran and its allies.

• Strategic importance: THAAD will work alongside other Israeli defence systems like the Iron Dome and David's Sling. It shows the U.S.'s commitment to protecting Israel and maintaining stability in the region.

• Operational context: This deployment comes as tensions rise, with Israel preparing for potential retaliation from Iran following key assassinations linked to Iran and Hezbollah. Iran has warned that any Israeli action could provoke a strong response.

Why is THAAD role in missile defence important?

THAAD’s role in missile defence is crucial, particularly in regions like the Middle East, where tensions are high, and missile threats are frequent. It enhances security by providing a reliable defence against ballistic missiles, contributing to the overall military readiness of both the U.S. and its allies.


THAAD is a powerful defence tool designed to protect against dangerous missile threats, offering precise and effective interception without relying on explosive warheads. Its recent deployment to Israel underscores its importance in safeguarding nations from rising geopolitical threats.
