Orang Airport (IATA: RGO, ICAO: ZKHM) is a small airport located in Orang County, approximately 40 kilometres south of Chongjin, North Hamgyong in North Korea. Built by the Imperial Japanese Army, designated as K-33 (Hoemun Airfield) by the USAF during the Korean War, Orang Airport is now controlled by the Korean People's Army. Hoemun Airfield was renamed when the original Chongin Airfield K-34 was abandoned after the Korean War. The airport is normally used by the military, though a small number of commercial passenger flights also operate there. The airport also serves Rason, which is about a three-hour drive away.
