龍山基地
With the Korean Armistice Agreement signed on July 27, 1953, the 18th FBW remained at Osan-Ni AB for defensive purposes until November 1954. Meanwhile, plans called for HQ Fifth Air Force (Advance) to move from Seoul National University to Yongsan Garrison in Seoul. This plan was changed, and in January 1954, the headquarters relocated to Osan-Ni AB, and established the base as the major hub of operations for U.S. air power in South Korea.
