Korean War The
Republic of Korea Army Capital Division captured Wonsan Airfield on 10 October 1950. On 13 October, Major General Field Harris, commander of the
1st Marine Air Wing, flew into the airfield, followed the next day by
VMF-312 and other elements of
Marine Aircraft Group 12. The airfield was used by the
United States Marine Corps and USAF under the designation
K-25. By 12 October the USAF's Cargo Combat Command was flying supplies into the airfield. On 24 September 2015, the first commercial civilian flight landed at Wonsan Airport as a part of an aviation-related tour with thirty passengers. Photographs of the inaugural flight reveal a very much redesigned terminal building, doing away with the original dual-terminal circular layout. The new terminal has a single L-shaped building. It is reported that the airport cost around $200 million to build, with most of the work being carried out by the military. In July 2015, the first major event, an aeronautics display and contest, took place at the airport. In September 2016 the
Wonsan Air Festival took place for the first time, with the
Korean People's Army Air Force and the North Korean airline
Air Koryo displaying a number of their aircraft. A second edition was planned for September 2017 but it was cancelled amidst international tensions.
Asiana Airlines became the first foreign airline to operate to the newly reconstructed airport at Wonsan. Air Koryo previously operated charter services from the original Wonsan Airport to South Korea prior to the end of the
Sunshine policy. In July 2018 a
C-17 of the
US Air Force's
204th Airlift Squadron collected 55 cases of human remains from Wonsan. It is thought that these are remains of US or other UN servicemen from the Korean War. The C-17 then flew to
Osan Air Base in South Korea. In April 2026 satellite imagery showed that the runway was extended and the airport went through upgrade and expansion. ==Infrastructure==
