Qatar Signs $42 Billion U.S. Defense Deal Including THAAD Air Defense Missile System

On May 14, 2025, President Donald Trump publicly endorsed a $42 billion mutual security agreement between the two nations during a ceremony held at Al Udeid Air Base in Qatar. The centerpiece of this deal is Qatar committing to purchasing the Terminal High Altitude Area Defense (THAAD) system—a major step forward in improving the nation’s air and missile defense.

THAAD was created by Lockheed Martin to neutralize incoming ballistic missiles using an effective “hit-to-kill” method at the very last stage of their flight. The THAAD system allows Qatar to intercept and destroy missiles long before they reach land, frequently high up in the atmosphere, reducing the risks of collateral damage. The AN/TPY-2 radar is capable of sensing and monitoring targets up to 1,000 km distant. It functions alongside systems such as the Patriot PAC-3 for layered protection against various threats.

The deal provides Qatar with THAAD batteries, radars, interceptors, command systems, and thorough preparation for its personnel. The agreements secure Qatar’s defense against intensifying challenges posed by missiles and drones in the region.

The presence of nearly 10,000 American troops at Al Udeid Air Base illustrates the longstanding military cooperation between Qatar and the United States. The agreement underlines Qatar’s importance in regional security and underscores the United States’ key objectives in the region.

Faced with increased instability and growing missile threats, Qatar’s decision demonstrates their focus on securing the country and cooperating with allies. This agreement serves to enhance the partnership between the United States and Qatar and establishes a model for future Gulf defense cooperation.
