Orang Airport (IATA: RGO, ICAO: ZKHM) is a small airport located approximately 40 kilometres from 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, Chongjin 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.
There is one runway in Chongjin Airport, originally 1,200m long, but which was extended to 2,000m. There are plans to further extend the runway to 4,000m to allow it to serve as a second international gateway to North Korea.
