G-500 Airport

Not applicable. The facility is an active military installation and has not been closed. The premise of a closed airport at this location is incorrect.

The site is the active ROK Army Aviation School, a major military airbase in Nonsan, South Chungcheong Province. Satellite imagery confirms a well-maintained facility with a main runway, numerous helipads, extensive hangar and maintenance facilities, and administrative buildings. It is a restricted military area and is not accessible to the public or used for any civilian aviation.

The site is the location of the Republic of Korea (ROK) Army Aviation School (육군항공학교). It serves as the primary training center for all ROK Army helicopter pilots, maintenance crews, and other aviation personnel. Established to centralize and standardize army aviation training, it has been crucial in developing South Korea's military rotary-wing and tactical air mobility capabilities for decades. Operations consist exclusively of military training flights using a variety of helicopters (such as the UH-60 Black Hawk, CH-47 Chinook, MD 500 Defender, and KUH-1 Surion) and light fixed-wing aircraft.

Not applicable. As a critical and fully operational military installation, there are no plans or prospects for it to cease operations or be converted for civilian use.
