U.S. Forces Korea (USFK) has moved Patriot missile defense batteries to Osan Air Base in Pyeongtaek, Gyeonggi, from other bases, raising speculation the systems could be deployed to the Middle East, according to sources on Friday.

Multiple government sources said additional Patriot batteries were recently spotted at the base alongside units already deployed there.

The Patriot missile system is an air defense system designed to intercept enemy ballistic missiles at low to medium altitudes.

The system is considered a key component of missile defense for USFK, along with the high-altitude interception system THAAD, or Terminal High Altitude Area Defense, designed to defend against North Korean missile threats.

Large U.S. military transport aircraft have also been spotted at the base. The C-5 Galaxy and C-17 Globemaster III transport aircraft were reportedly observed at Osan Air Base.

While C-17 aircraft regularly land at the base, the appearance of the larger C-5 transport aircraft is considered unusual.

Tensions in the Middle East have escalated following recent U.S. and Israeli strikes on Iran, leading some observers to speculate that preparations may be underway to move Patriot batteries stationed in Korea to the region.

Two Patriot batteries deployed with USFK were temporarily rotated to the Middle East during Operation Midnight Hammer, a strike targeting Iranian nuclear facilities in June last year, and returned to Korea in October.

It remains unclear whether the latest movement is related to potential deployments to the Middle East or preparations for next week's annual Freedom Shield joint military exercise between Korea and the United States.

“It would not be appropriate for the government to comment on the operational deployment of United States Forces Korea,” a Ministry of National Defense official said during a briefing.

USFK does not comment on the movement, relocation, or potential repositioning of specific military capabilities or assets for operational security reasons, a USFK official said when asked about the speculation.

USFK remains focused on maintaining a strong, ready, and combat-credible force posture on the Korean Peninsula, and the United States remains firmly committed to the defense of South Korea, the official added.
