Early years Taichung International Airport was constructed during the era of
Japanese rule and was named . The
United States Air Force (USAF) had been garrisoning the base with two fighter squadrons until the
Sino-American Mutual Defense Treaty came into force on March 3, 1955. The airport then expanded in 1954 according to the
Sino-American Mutual Defense Treaty, and later renamed
Ching Chuan Kang Air Base (CCK) after General
Qiu Qingquan. In 1966 the American Air Force established a joint forces air-base at CCK. It was the largest air force base in the
Far East at the time, allowing
Boeing B-52 Stratofortress bombers to land. During the
Vietnam War, CCK became a depot for the USAF. The US Military used CCK and
Shuinan Airport to run many of its long-distance Vietnam, Cambodia and Laotian bombing, scouting and cargo transport runs during the
Vietnam War era. This base was shut down and most American facilities were removed after the U.S. established diplomatic relations with the
People's Republic of China in 1979.
Developments since the 2000s Construction of passenger facilities was completed in September 2003 and civilian services began on March 5, 2004, replacing the old
Shuinan Airport located closer to downtown Taichung. Ching Chuan Kang Airport has since become the only airport serving Taichung. The airport was promoted to an international airport on January 3, 2017, and renamed Taichung International Airport. In 2003, with the demand to develop cross-strait and other international air routes from Taichung City, it was decided to transfer the airport from Shuinan Airport (TXG) to RMQ; since RMQ had been for the airbase for the
Republic of China Air Force, the Taiwanese
Civil Aeronautics Administration held negotiations with the air force, which led to the air force allowing an edge for building a new civilian terminal. The first terminal was completed in 2004, and all flights moved from TXG to RMQ soon afterwards. In 2008, officials decided to build another terminal. Terminal 2 now handles all international and cross-strait flights, while the older Terminal 1 serves domestic flights. ==Airlines and destinations==
