502d Air Operations Group emblem(Approved 25 August 1953)[1]

The502d Air Operations Group in an inactiveUnited States Air Force unit. It was last active in October 2006 atHickam Air Force Base, Hawaii, where it had served as the umbrella forintelligence and operational support units underPacific Air Forces

The unit was first activated as the502nd Tactical Control Group in December 1945. In 1950 it was rushed to Korea where it fought in theKorean War, earning twoPresidential Unit Citations for its actions. It remained under Far East Air Forces after the war until it was inactivated in October 1957.

At the beginning of the Korean War, theUnited States Air Force's only tactical control group was the 502d atPope Air Force Base, North Carolina. To respond,Fifth Air Force organized the 6132d Tactical Air Control Squadron, which established a full-scale Tactical Air Control Center atTaegu Air Base, South Korea on 23 July 1950.

Less than three months later, the 502nd and its subordinate squadrons moved from Pope to Korea. Elements left behind at Pope by the 502d were used to form the 507th Tactical Control Group there.^[2] In October 1950 the 502d replaced the 6132nd TCS in the mission of directing tactical air operations in Korea. Through its 605th Tactical Control Squadron, the group operated the Tactical Air Control Center and worked with theUnited States Army in a Joint Operations Center. The group's two aircraft control and warning squadrons operated Tactical Air Direction Centers, which used stationary and mobileradar and communications equipment to guide aircraft onclose air support missions.^[1] In November a third aircraft control and warning squadron was activated to reinforce the group.

The group also deployedTactical Air Control Parties, which accompanied ground units to communicate with strike aircraft. These small detachments followed advancing U.S. and allied troops into North Korea in October and November 1950, but the Chinese Communist offensive soon overran several of them. The 502d TCG's headquarters and the Tactical Air Control Center, which had been operating fromSeoul in November and part of December, were forced to return to Taegu.^[1]

After deployment to theKorean War, in January 1951, the threeAN/MPQ-2 radars of the3903rd Radar Bomb Scoring Group RBS detachments were transferred to the operational control of the 502nd TCG.^[3] The MPQ-2 radars guidedMartin B-26 Marauders against enemy positions in front of the25th Infantry Division."^[4] On February 23, 1951, the firstBoeing B-29 Superfortress mission controlled by an MPQ-2 was flown.^[5]

During the spring and summer of 1951, the 502d directed night bombing of enemy targets, including troop concentrations, supply dumps, and motor convoys. As United Nations ground forces drove the enemy back across the38th Parallel, the group returned to Seoul in June, along with the Tactical Air Control Center and the Joint Operations Center returned to Seoul. In October, the 502nd set up a communications station 100 miles behind enemy lines onCho-do Island, three miles off the North Korean coast.^{[note 1]} From this location the detachment guidedfighter aircraft against enemy airplanes inMiG Alley,bombers against strategic targets along theYalu River, andsearch and rescue aircraft toward survivors who had ditched at sea.

On 6 June 1952, the 502nd was instrumental in the destruction of nineMikoyan-Gurevich MiG-15 aircraft by directingNorth American F-86 Sabres to maneuver into a position from which they could advantageously attack the MiGs. In addition, during 1952, Detachment 2 of the 608th Squadron was credited with the first (and possibly the only) confirmed kill of a multi-engine enemy bomber. The following month, the 502nd guided warplanes in attacks on enemy troop formations that blunted communist offensives until theKorean Armistice Agreement was signed in July 1953.^[1]

Archived fromthe original(PDF) on 27 November 2011. Retrieved4 February 2013.Ground-based radar was first tried on November 28, when a detachment of the3903d Radar Bomb Scoring Squadron used truck-mounted AN/MPQ-2 radars to guide B–26s against enemy. … The 502d Tactical Control Group (TCG) was given the task of developing procedures and equipment for this mission. Initially, radio beacons placed along the front lines were used, but these did not permit sufficiently precise bombing parameters. In January 1951, the group assumed operational control of the 3903d's three MPQ-2 radar detachments. Nine months later the 502d assumed complete control of the detachments, which allowed the 3903d Squadron to return to the United States. The MPQ-2 detachments then became full-scale tactical air-direction posts called Tadpoles. Code-named Hillbilly, Beverage, and Chestnut, they were positioned about ten miles behind the front lines near the command posts of the I, IX, and X Corps.
