U.S. to Deploy Missile Defense System and About 100 Troops to Israel

The United States is sending an advanced missile defense system to Israel, along with about 100 American troops to operate it, the Pentagon announced on Sunday. It is the first deployment of U.S. forces to Israel since the Hamas-led attacks there on Oct. 7, 2023.

President Biden directed Defense Secretary Lloyd J. Austin III to deploy the Terminal High Altitude Area Defense system, or THAAD, and its crew, Maj. Gen. Patrick Ryder, the Pentagon press secretary, said in a statement on Sunday.

The move will put American troops operating the ground-based interceptor, which is designed to defend against ballistic missiles, closer to the widening war in the Middle East. It comes after Iran launched about 200 missiles at Israel on Oct. 1 and as Israel plans its retaliatory attack.

The THAAD battery, a mobile defense system, will give the Israel Defense Forces another layer of protection to defend cities, troops and installations from short- and intermediate-range ballistic missiles like those deployed by Iran in its last attack.

When asked about it on Sunday, Mr. Biden said only that he had ordered the Pentagon to deploy the system “to defend Israel.” General Ryder said in his statement that the battery would “augment Israel’s integrated air defense system.”

“This action underscores the United States’ ironclad commitment to the defense of Israel, and to defend Americans in Israel, from any further ballistic missile attacks by Iran,” the statement said. “It is part of the broader adjustments the U.S. military has made in recent months to support the defense of Israel and protect Americans from attacks by Iran and Iranian-aligned militias.”
