WASHINGTON - The United States will deploy a Terminal High-Altitude Area Defense (THAAD) battery to Israel in order to bolster the country's air defense in the wake of missile attacks from Iran, the Department of Defense said Sunday.

According to a statement issued by Pentagon press secretary Patrick Ryder, along with the deployment, which was authorized by Defense Secretary Lloyd Austin at the direction of President Joe Biden, will be the dispatch of associated crew of US military personnel to Israel.

While expected to "augment Israel's integrated air defense system", the THAAD deployment is "part of the broader adjustments the US military has made in recent months, to support the defense of Israel and protect Americans from attacks by Iran and Iranian-aligned militias," Ryder said.

The United States deployed a THAAD battery to the Middle East following the Oct 7, 2023 attack on Israel by Hamas.
