6147th Tactical Control Group

The 6147th Tactical Control Group was a United States Air Force tactical air-control formation created during the Korean War to connect frontline ground forces with aircraft operating over the battlefield. It served under the Far East Air Forces’ Fifth Air Force and became known by the nickname “Mosquitoes,” reflecting the small observation aircraft used by its airborne forward air controllers. The unit developed from wartime experience with forward air control. Second World War operations had demonstrated the value of using relatively slow aircraft to locate targets, communicate with ground commanders, and direct faster fighter-bombers onto targets that could not be identified reliably from the air alone. United States doctrine after the war distinguished between ground forward air controllers, airborne tactical air coordinators, tactical air-control parties, and air liaison officers. During the early Korean War, Fifth Air Force personnel adapted these concepts under urgent combat conditions. The group’s initial mission was organized at Taejon within the Joint Operations Center. Three pilots and two Stinson L-5 Sentinel aircraft were initially assigned for airborne control, but radio problems led the pilots to borrow Ryan L-17 Navions from the 24th Infantry Division. On 9 July 1950, Lieutenants James A. Bryant and Frank G. Mitchell flew the first missions as airborne controllers. They directed Lockheed F-80 Shooting Stars against targets near the front and helped demonstrate the operational value of aircraft dedicated to target spotting and attack control. The following day, Lieutenant Harold E. Morris used a North American T-6 Texan while controlling Royal Australian Air Force F-51 Mustangs. The T-6 proved better suited to the role, and it became the group’s characteristic aircraft. The 6147th Tactical Control Squadron, Airborne, was organized at Taegu and activated on 1 August 1950. Its aircraft carried smoke grenades and phosphorus smoke rockets to mark targets, while additional fuel capacity extended time over the battlefield. Communications aircraft based on C-47 transports operated as airborne radio centers under the “Mosquito” call signs, linking controllers, tactical aircraft, naval aviation, ground units, and command centers. The airborne controller normally flew in the front cockpit while an observer occupied the rear cockpit. As United Nations forces advanced after the Inchon landings, the squadron directed attacks against retreating North Korean forces and provided reconnaissance for advancing ground units. Its duties expanded beyond close air support to include artillery adjustment, deep reconnaissance, search-and-rescue support, night direction for Douglas B-26 Invader missions, parachute-drop coordination, and airborne communications relay. The unit moved repeatedly as the front changed, operating from Taegu, Kimpo, Seoul, Pyongyang East, Pyongtaek, and Chunchon. In January 1951, a C-47 radio-relay aircraft improved communications between the Joint Operations Center and controllers operating over rapidly shifting battle lines. In April 1951, the organization was elevated to group level and incorporated three tactical-control squadrons. Two provided airborne controllers, while another supplied ground tactical air-control parties to the United States Army. From Chunchon, the group later directed interdiction operations and continued close-support work. In the final days of the war, it helped allied aircraft attack forces involved in a last North Korean offensive near the Kumsong River. The group flew 40,354 missions during the conflict, received two United States Presidential Unit Citations and the Korean Presidential Unit Citation, and completed its final mission on 15 June 1953. It is therefore best understood not as a commercial brand, but as a historically significant military organization whose “Mosquitoes” identity became associated with airborne forward air control in Korea.

The 6147th Tactical Control Group emerged from the Fifth Air Force’s effort to provide reliable airborne forward air control during the opening phase of the Korean War. Earlier United States military experience had shown that slow observation aircraft could find and mark targets for fast-moving combat aircraft, but the Korean battlefield required the concept to be organized quickly. The Fifth Air Force used personnel operating through the Joint Operations Center at Taejon to create an airborne-control capability in July 1950. Lieutenants James A. Bryant and Frank G. Mitchell flew the first recorded airborne-control missions on 9 July 1950. Because the radios in the assigned Stinson L-5 Sentinels were not functioning adequately, the pilots used Ryan L-17 Navions borrowed from the 24th Infantry Division. They directed F-80 fighters against targets near the front, demonstrating that dedicated airborne controllers could significantly improve the effectiveness of tactical air attacks. On 10 July, Lieutenant Harold E. Morris’s use of a T-6 Texan showed that the trainer was more suitable for the mission. The T-6 combined low-speed handling, endurance, visibility, and a useful communications and marking load. The force moved to Taegu and was organized as the 6147th Tactical Control Squadron, Airborne, effective 1 August 1950. The squadron’s T-6 aircraft used smoke markers and phosphorus rockets to identify targets. C-47 aircraft served as airborne communications centers, allowing controllers to coordinate with tactical aircraft and ground forces. These relay aircraft operated under several “Mosquito” call signs, and the nickname became associated with the controller crews and their aircraft. The unit’s operational role grew during the United Nations advance after the Inchon landing. Its crews directed attacks on retreating enemy formations, assisted advancing ground forces, adjusted artillery, conducted visual reconnaissance, supported search-and-rescue and parachute operations, and helped direct night missions. The squadron’s bases tracked the movement of the front: it operated from Taegu, Kimpo, Seoul, Pyongyang East, and later Taegu again during the Chinese intervention and United Nations withdrawal. A C-47 radio relay added in January 1951 helped maintain command connectivity while controllers worked over changing combat sectors. In April 1951, the organization became the 6147th Tactical Control Group. It included the 6148th, 6149th, and 6150th Tactical Control Squadrons, with two squadrons providing airborne control and one supplying ground tactical air-control parties. The group later moved through Pyongtaek and Chunchon, where it supported close air support and interdiction. An attached 942nd Forward Air Control Squadron was listed with the organization in June 1953. The group participated in the closing combat of the war, including operations against a final enemy offensive near the Kumsong River. Its last mission was flown on 15 June 1953 by First Lieutenant Chester L. Brown. By the end of the conflict, the organization had flown 40,354 missions and had received two Presidential Unit Citations and the Korean Presidential Unit Citation. The 6147th Tactical Control Group’s history illustrates the institutional development of airborne forward air control and the close integration of air and ground operations in Korea.

  Adoption of dedicated airborne forward air controlStrategy

  Background

  The Korean War created an urgent need to identify targets for fast tactical aircraft and coordinate attacks with ground formations.

  Action taken

  The Fifth Air Force organized airborne controllers using slow observation aircraft, later standardizing on the T-6 Texan and supplementing it with C-47 communications aircraft.

  Aftermath

  The arrangement became the basis for the 6147th Tactical Control Squadron and later the group-level organization that supported more than 40,000 missions.
