U.S. military transport aircraft have been spotted arriving at and departing from a U.S. air base in Korea over the past week amid speculation that the U.S. Forces Korea (USFK) may be deploying some of its assets to the Middle East amid the Iran war.

According to real-time flight tracking website Flightradar24, several C-5 and C-17 U.S. transport aircraft have landed at Osan Air Base in Pyeongtaek, Gyeonggi, since late last month and departed between Wednesday and Saturday.

At least two C-5 aircraft arrived at the air base in late February and were spotted departing last Saturday and Monday, while C-17 aircraft departed between Tuesday and Saturday, with six confirmed to be heading to Anchorage, Alaska.

The C-17 aircraft regularly stops at the key U.S. base to transport U.S. assets and personnel, but the arrival of the C-5 appears to be rare.

The latest move has fueled speculation that the USFK may be preparing to move Patriot missile defense systems, as it is known to have recently relocated some Patriot batteries to Osan Air Base from other U.S. bases.

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 were previously deployed to the Middle East in June last year when Washington carried out major operations targeting Tehran's nuclear facilities, before they were returned to Korea in October.

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 Terminal High Altitude Area Defense, or Thaad.

It was not immediately known whether the aircraft carried missile systems or their exact destinations, though the timing has raised speculation that they may have been bound either for the U.S. or the Middle East.

It also 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.

The USFK said it does not comment on the relocation or movement of its assets due to operational security, while Seoul's defense ministry said it is not appropriate to comment on USFK troop operations.
