Terminal High Altitude Area Defense (THAAD), formerly Theater High Altitude Area Defense, is an American anti-ballistic missile defense system designed to shoot down short, medium, and intermediate-range ballistic missiles in their terminal phase (descent or reentry) by intercepting with a hit-to-kill approach.[2][3] THAAD was developed after the experience of Iraq's Scud missile attacks during the Gulf War in 1991.[4] The THAAD interceptor carries no warhead, instead relying on its kinetic energy of impact to destroy the incoming missile.

Originally a United States Army program, THAAD has come under the umbrella of the Missile Defense Agency.[5] The Navy has a similar program, the sea-based Aegis Ballistic Missile Defense System, which also has a land component ("Aegis Ashore"). THAAD was originally scheduled for deployment in 2012, but initial deployment took place in May 2008.[6][7] THAAD has been deployed in the United Arab Emirates, Israel, Romania, and South Korea.
On 17 January 2022, THAAD made its first operational interception, of an incoming hostile medium-range ballistic missile in the UAE.[8]
