Yechon (Yecheon) Air Base
3738'N, 12821'E

Yechon Air Base (also spelled Yecheon and also referred to as K-58) is located in a valley at an elevation of 354 feet (108 meters). The Naesong Chon (River), flowing west to east, is about 4 miles (7 km) south of Yechon. This river can provide an additional moisture for fog and cloud formation. Hills and mountains cover about 75 percent of the Korean peninsula, with the remainder covered by scattered lowlands. Most of the rivers are short, swift, and shallow due to topography, narrowness, and sand deposits within the river. The base is surrounded by fairly low rugged hills within 4-5 miles (7-9 km). Elevations are in the range of 500-700 feet (152-213 meters). About 20-25 miles (37-46 km) west is the Sobaek Range, which forms a north-south interior divide on the Korean peninsula. These mountains have a general elevation of 3,500 feet (1,067 meters).

Yechon Air Base, though primarily a Republic of Korea Air Force facility, also hosts US Marine Corps squadrons as part of their WESTPAC rotation. Units rotating through often patricipate in various exercises during their stay. Yechon also served as the storage point for USMC aircraft War Reserve Munitions, which would provide prepositioned stockpiles in the event of a conflict on the peninsula.

In 1981 the United States and the Republic of Korea signed a memorandum of understanding concerning the pre-positioning USAF-owned combat communications assets at the following ROK Air Bases: Cheong Ju, Sachon, Suwon and Yechon. Under the agreement the ROKAF was required to provide the following at Yechon Air Base:

  • A: Provide rent free and at no cost to the USAF 6,664 square feet of outside storage space near the Supply Squadron building. Allow the USAF to connect into existing electrical system in order to provide security lighting.
  • B: Provide rent free and at no cost to the USAF inside storage space within the Base Supply warehouse to store one conex container.
  • C: Permit the use of base motor pool facilities as required by USAF personnel for routine operator maintenance of vehicles and mission esseatial emergency repairs. Routine operator maintenance includes, but is not limited to, cleaning, lubrication, oil changes, maintaining tire pressures and corrosion control. USAF will provide all reqviired materials.
  • D: Provide telephone communications support, emergency medical support, emergency firefighting support and any fuels and/or lubricants needed for USAF personnel during deployments and visits to perform periodic maintenance and operational testing of USAF assets.
  • E: All requests for reimbursement for support provided in paragraph D above will be submitted annually or as needed to the comptroller 51 Composite Wing, Osan AB, USAF.
  • F: Provide for protection of pre-positioned USAF assets as part of their installation security program.

In 2002 the United States and the Republic of Korea agreed to a Land Partnership Plan (LPP) for the reorganization of US facility assets in the ROK. This included the closure, partial closure, and return of a wide array of facilities to the ROK. Yechon Air Base, however, was not included in the original 2002 agreement or the 2004 ammendments, as it was an ROKAF facility.
