participated in a constant stream of exercises and operations. As the United States Air Force (USAF) built up its forces in the Pacific as the Vietnam War grew larger the squadron moved to Ching Chuan Kang Air Base, Republic of China (usually called "CCK"). Although the squadron itself was not stationed in Viet Nam, it flew C-130s to augment task forces and other operational organizations during Vietnam War until it was inactivated in 1971 when the 314th wing returned to the US. Its mission, personnel and equipment were transferred to the 21st Tactical Airlift Squadron, which moved on paper to CCK from Naha Air Base, Okinawa. Generally, the aircrew work-rest cycle for deployed C-130 crews in 1968 through 1970 was 12 hours on and 14 hours off for five cycles. The crew reported for duty in the evening, worked 12 hours, rested 14 hours, then reported for duty two hours later than the previous evening. By the 5th cycle, the crew had delayed its report time 10 hours and was now reporting in the morning. The crew worked 12 hours that day, ate, slept for 12 hours, and then reported for work again that evening. At the end of that night, the crew had been awake for 24 hours. As a result of this work-rest schedule the crews were never properly rested Lineage Constituted as the 346th Troop Carrier Squadron, Medium on 10 May 1949 Activated in the reserve on 26 June 1949 Ordered to active service on 16 April 1951 Inactivated on 16 January 1953 Redesignated 346th Troop Carrier Squadron, Assault, Rotary Wing on 8 December 1954 Activated on 8 March 1955 Inactivated on 9 July 1956 Redesignated 346th Troop Carrier Squadron, Assault, Fixed Wing on 27 July 1956 Activated on 8 October 1956 Redesignated 346th Troop Carrier Squadron, Assault on 1 July 1958 Redesignated 346th Troop Carrier Squadron, Medium on 1 April 1963 Redesignated 346th Troop Carrier Squadron on 1 March 1966 Redesignated 346th Tactical Airlift Squadron on 1 May 1967 Inactivated c. 31 May 1971 Assignments 516th Troop Carrier Group, 26 June 1949 – 16 January 1953 516th Troop Carrier Group, 8 March 1955 – 9 July 1956 Eighteenth Air Force, 8 October 1956 (attached to 513th Troop Carrier Group) Ninth Air Force, 1 September 1957 (attached to 513th Troop Carrier Group until 8 October 1957, 513th Troop Carrier Wing until 30 June 1958, 464th Troop Carrier
