Kunsan K-8 Air Base (Korean: 군산공군기지) is a United States Air Force base located at Gunsan Airport, on the west coast of the Korean peninsula bordered by the Yellow Sea.
It is located in the town of Gunsan (also romanized as Kunsan), about 180 kilometres (110 mi) south of Seoul.
In their rapid advance, the invading North Koreans captured Kunsan Air Base on 13 July 1950.
By August, construction had progressed to the point that heavier units could be based at Kusan and the USAF assigned the 3rd Bombardment Wing to Kunsan.
The 474th bombed and strafed such targets as bunkers, troops, artillery positions, bridges, vehicles, airfields, and power plants, and sometimes escorted bombers that attacked munitions factories and other objectives.
During 1957–1958, a Republic of Korea Air Force (ROKAF) F-86 Sabre crashed into the Yellow Sea south of the base after having a flame out and a USAF F-100 Super Sabre crashed in the rice paddies north of the base.
This ROKAF unit was the only permanently assigned flying contingent at Kunsan until after the Pueblo incident in 1968.
At an unknown date in this time frame, the US Army 38th Air Defense Artillery Brigade assigned Battery B, 6th Battalion, 44th Air Defense Artillery Regiment, a HAWK missile unit to the base.
Under the command of Col. Jack Hayes, F-4D Phantom IIs arrived at Kunsan on January 29, 1968, as part of Operation Combat Fox.
Aircraft came primarily from Misawa AB Japan, 475th Tactical Fighter Wing after it was inactivated and as were most of the personnel initially assigned to the 3rd TFW.
In September 1974, the 8th Tactical Fighter Wing, the "Wolf Pack," was transferred from Ubon Air Base, Thailand to replace the 3rd at Kunsan.
In February 2018, it was announced that following the completion of construction of hangars and supporting facilities at the base, 12 MQ-1C Gray Eagle UAS' will be deployed to Kunsan in March/April 2018.
