After the end of the Korean War, the 30th Weather Squadron began to turn over several of its locations to the Republic of Korea (ROK) Air Force. In 1957, headquarters of the 30th moved from Korea to Japan, to oversee the weather detachments in Korea and Japan with the inactivation of the 20th Weather Squadron. In 1957, the 30th was assigned to the 10th Weather Group. In 1959, the 30th was inactivated and its detachments assigned directly to the 10th Weather Group. The 10th Weather Group was inactivated in 1960.
