...Operations:: From Nov 1951 to mid Oct 1955, supported 5th Air Force and other Far East Air Forces agencies in Korea by installing, operating and maintaining radio, telephone, and teletype communications networks linking Air Force and other military installations in Korea with bases in Japan. Operated communications centers serving 5th Air Force's headquarters at Seoul and Taegu until Jan 1954 and at Osan-Ni thereafter. In addition, from Nov 1954 to Feb 1955, supported a Republic of Korea Air Force Technical Training school. From Jan to Apr 1955, occasionally sent men and equipment as far away as Formosa to support mobility exercises.

...Moved to Japan in Oct 1955. While continuing to survey, install, operate, and maintain radio, telephone, and teletype communications in support of 5th Air Force and Southeast Asia Treaty Organization (SEATO) operations, the group became more mobile to provide communications support anywhere in the area of Far East (later, Pacific) Air Forces when natural disasters such as floods or typhoons destroyed or damaged fixed facilities. Moved to Okinawa in 1957 with no change in basic operations. Came under 13th Air Force control in Sep 1958, about the same time the group deployed men and equipment to Formosa to augment 13th Air Force communications links there during the crisis over Quemoy Island..

...The group acquired a tactical air control function in April 1959 with assignment of the 605th Tactical Control Squadron. It lost its communications construction squadron at the same time, but retained both radio relay and mobile communications squadrons.

...Moved to Clark AB, Philippines, in Oct 1959, continuing communications and tactical control support for 13th, 5th, and Pacific Air Forces operations. Also trained indigenous personnel in communications and tactical control operational techniques. In Oct 1961, the group lost all squadrons although another mobile communications group was briefly attached for control until January 1962. The 5th Tactical Control Group maintained and "operating" radar section within it headquarters, however, and retained it tactical control capability. Detachments of the group, located in Southeast Asia, provided training of indigenous Air Force personnel in operation communications equipment for tactical control for the next several years.

...Two tactical control squadrons joined the group in April 1964, and July 1964, a tactical control maintenance squadron was assigned. The group continued to provide tactical control support and mobile capability to support PACAF and 13th and 5th Air Force operations.

...Two direct air support squadrons joined the group in 1968. The group continued to provide emergency mobile communications and electronics facilities to replace or augment fixed PACAF installations. From late 1970 to late 1971, the group also maintained permanent detachments in Thailand and Korea, and several months in 1971, the 22nd Tactical Air Support Squadron (light), equipped with 0-2 Aircraft, was part of the group.

...The group began phasing down in September 1971, when its Thailand detachment was closed and the 22nd TASS transferred.. From then until its inactivation at the end of 1971, the group controlled a single tactical control squadron (the 605th) and it detachment in Korea.

...Redesignated as the 5th Tactical Air Control Group, the group activated at Osan AB, Korea, on 8 Jan 1980 as a component of the 51st Composite Wing (Tactical). To perform its mission the group comprised a direct air support squadron, a tactical air control squadron, a tactical air control center squadron, and a separate detachment.

...During the 1980's the group supported the Korean Tactical Air Control System by maintaining ground radar sites with air and ground support provided by forward air controllers, air support operations centers, tactical air control parties, and communications personnel and equipment. Served the 314th Air Division for June 1982 to September 1986, when it was assigned directly to 7th Air Force. Participated in numerous PACAF training exercises in Korea and the western Pacific, working with other branches of the U.S. Armed Forces and units of other nations. Its 19th Tactical Air Support Squadron converted in 1983 form OV-10A to OV-37B aircraft, but returned to OV-10's in 1985. In August 1989, the group moved form Osan AB to Suwon AB, South Korea, but it returned to Osan in October 1990 when it was assigned to the 51st Tactical Fighter Wing.
