Owning THAAD Does Not Mean the Ability to Use It: Saudi Arabia Between Defensive Independence and Tactical Dependence

In recent days, American media reports have confirmed that the Pentagon is deploying additional batteries of the THAAD (Terminal High Altitude Area Defense) system and Patriot systems throughout the Middle East, in preparation for a potential Iranian response to possible American strikes. The United States has sent over 100 aircraft in recent weeks, carrying advanced air defense equipment to its bases in the region. What is striking here is not the scale of the deployment, but the irony: Saudi Arabia paid $15 billion to purchase seven THAAD batteries between 2017 and 2025, activating the first battery in July 2025; yet Washington needs to deploy its own systems to protect the region when the threat becomes real.

From a military perspective, this is not surprising. Possessing advanced weaponry does not equate to the ability to use it effectively under the pressures of war. The THAAD system is one of the most complex missile defense systems in the world: the AN/TPY-2 radar can detect ballistic missiles at distances of up to 1,000 kilometers, but it requires integration with an American command and control network, operators trained for years, and a complex logistics chain for maintaining interceptors and infrared guidance systems. Saudi Arabia received its first battery only seven months ago, after training at Fort Bliss in Texas. In any serious military assessment, this is an insufficient period to transform a complex system into an independent combat capability.

The Saudi contract with Lockheed Martin included 360 interceptors, 44 launch platforms, and seven radar units, with a delivery schedule extending until 2028. However, the gradual delivery means that Saudi Arabia will not have complete defensive capability for years to come. Even when the seven systems are complete, the fundamental problem remains: THAAD is not a weapon that you operate alone. The system operates within an integrated American command structure known as IAMD (Integrated Air and Missile Defense), linking radars and missiles to command centers in Qatar and Bahrain and data from American spy satellites. Saudi Arabia can launch the missiles, but the eye that sees and the mind that decides remain partially in Washington's hands.

This situation explains why the United States continues to deploy its own systems in the region. When confrontation with Iran becomes imminent, one cannot rely on modern systems operated by crews that are still learning. The U.S. military knows that a THAAD battery requires at least five years of field operation before it becomes reliable in a real battle. The UAE has operated THAAD since 2016 and has better integration with American systems, but even Abu Dhabi has benefited from additional American batteries during previous crises.

Saudi Arabia is trying to mitigate this dependence through a localization program linked to Vision 2030. In May 2025, Lockheed Martin and the Arab International Company for Metal Structures (AIC Steel) announced the local production of the first MRP-T (Missile Transport Platform) in Jeddah. This is a symbolic achievement, but it does not change the strategic equation. The MRP-T is merely a logistical platform for transporting missiles, not the missile itself, the radar, or the guidance software. The critical components—the infrared seeker, processing chips in the radar, and algorithms for distinguishing between missiles and decoys—remain entirely American and are protected by ITAR (International Traffic in Arms Regulations) laws that prevent the transfer of critical technology.

What we are witnessing in the Gulf today is a manifestation of a structural contradiction: Gulf states are spending tens of billions on advanced weapons to achieve "strategic independence," yet at the critical moment, they discover that true independence cannot be bought with money. Defensive capability is built on decades of investment in training, research, development, and field experience. The United States has spent 40 years and tens of billions developing THAAD, operating it in the UAE, South Korea, and Israel before trusting its capabilities. Saudi Arabia wants to leapfrog these stages by purchasing ready-made systems, but war does not fall for shortcuts.

The problem lies not in the intent, but in the logic governing Gulf military purchases. The political logic says: buy the most expensive weapons to demonstrate power and strengthen ties with Washington. The military logic says: buy what you can operate, maintain, and use effectively without foreign assistance. The gap between these two logics explains why Saudi Arabia possesses THAAD but still needs American THAAD when the time for a real test comes.
