The airfield was originally constructed in the 1960s with assistance from the Soviet Union.^[4] After a long period of dormancy during and after the Khmer Rouge era, the airport formally reopened on 5 January 2007.^[5] The runway was extended to a length of 3,300 metres (10,827 ft) in order to accommodate 4E class aircraft. The 2 existing taxiways were widened and a cargo apron for 4E class aircraft was added.^[6] However, after the crash of PMTair Flight U4 241 in June 2007 shortly before landing, scheduled passenger flight service to the airport was discontinued until 2011.^[7]
