Overview
The 18th Operations Group is a United States Air Force operational unit headquartered at Kadena Air Base on Okinawa, Japan. It forms the flying and operational core of the 18th Wing, a composite air organization responsible for a broad range of missions in the Western Pacific. Unlike a commercial brand, the group is a military organization whose identity is expressed through lineage, heraldry, operational capability and service traditions rather than consumer products or commercial offerings. The group traces its institutional lineage to the 18th Pursuit Group, authorized and activated in Hawaii in January 1927. It is therefore a successor to one of the Army's early combat aviation groups and is among the oldest continuing lineages represented in the modern Air Force. Its heritage includes fighter, fighter-bomber, tactical fighter and present-day operations-group designations. The unit's emblem is a fighting cock accompanied by the Latin motto “Unguibus et Rostro,” meaning “With Talon and Beak.” The emblem was selected in the early 1930s and symbolizes aggressiveness and courage in combat. Before the Second World War, the organization operated aircraft including the Boeing P-26 and Curtiss P-36 and later prepared for combat with Curtiss P-40 fighters. The Japanese attack on Pearl Harbor on 7 December 1941 damaged the group severely, destroying or damaging many aircraft on the ground at Wheeler Field. After rebuilding and retraining, the group deployed to the South Pacific in 1943. It flew patrol, escort, ground-support and interdiction missions from locations including Guadalcanal, the Solomon Islands, New Guinea and the Philippines. Its aircraft during this period included P-39 Airacobras, P-38 Lightnings, P-61 Black Widows and P-70 Havocs. The group received a Distinguished Unit Citation for its actions around Ormoc Bay in November 1944. After the Second World War, the organization served in the Far East and became one of the first overseas fighter units to receive jet aircraft, operating the Lockheed F-80 Shooting Star. It later flew F-47 Thunderbolts, F-51 Mustangs and other aircraft. During the Korean War, its successor fighter group deployed to South Korea and conducted close air support, interdiction, armed reconnaissance and counter-air missions. The unit operated through changing bases and difficult conditions, transitioned from F-80s and F-51s to F-86 Sabres, and earned additional Distinguished Unit Citations. Its Korean War heritage also includes the actions of Major Louis Sebille, who was posthumously awarded the Medal of Honor after continuing an attack despite severe aircraft damage. The lineage was inactivated in 1957, briefly reactivated as the 18th Tactical Fighter Group from 1978 to 1981, and redesignated and activated as the 18th Operations Group on 1 October 1991. That reorganization accompanied the conversion of the 18th Wing to an objective-wing structure. The modern group combines fighter, rescue, air refueling, airborne command-and-control, air control, aeromedical evacuation, operations-support and expeditionary reconnaissance capabilities. Reference material describes it as one of the Air Force's largest combat operations groups, with approximately 842 active-duty personnel and about 80 aircraft, although such figures can change over time. The group's current role is to generate and coordinate operational airpower for the 18th Wing and broader regional contingency requirements. Its units operate or support F-15 Eagle fighters, E-3 Sentry airborne warning and control aircraft, KC-135R Stratotankers, HH-60 rescue helicopters and MQ-9 Reaper remotely piloted aircraft. Its geographic position at Kadena gives it an important role in air defense, surveillance, command and control, combat search and rescue, aerial refueling and rapid response across the Indo-Pacific.
History
The 18th Operations Group's lineage began with the activation of a provisional pursuit group at Wheeler Field, Hawaii, on 21 January 1927. It soon became the 18th Pursuit Group and included pursuit squadrons that formed the basis of its early fighter identity. During the 1930s it adopted the fighting-cock emblem and motto associated with its combat heritage. The group moved through aircraft generations from the P-26 and P-36 to the P-40 before the United States entered the Second World War. The attack on Pearl Harbor on 7 December 1941 caused extensive losses. Aircraft were destroyed or damaged on the ground, and the group required re-equipment before resuming patrol and training duties. In 1943 it entered operations in the South Pacific under Thirteenth Air Force. Its missions included protection of Allied bases, bomber escort, attacks on enemy installations and support of ground forces. It later moved through New Guinea and the Philippines, conducting long-range fighter operations over the Bismarck region, the Netherlands Indies, Borneo, Luzon and surrounding areas. Its performance during the Ormoc Bay action in November 1944 earned a Distinguished Unit Citation. After the war, the group operated in the Far East and transitioned to jet operations with the F-80 Shooting Star, becoming the first overseas fighter unit to receive that aircraft. It was re-manned after a period of reduced activity in 1947 and subsequently operated F-47s, F-51s and F-80s. In 1948 it became subordinate to the 18th Fighter Wing, which was redesignated the 18th Fighter-Bomber Wing in 1950. The Korean War brought intensive combat operations. The group deployed from the Philippines to South Korea in July 1950 and initially flew F-80s before transitioning to F-51 Mustangs for close support and interdiction. It attacked vehicles, artillery, supply points, airfields, factories and troop concentrations. Changing front lines and base conditions required repeated relocations between Korean and Japanese bases. The group later transitioned to F-86 Sabres and continued counter-air and ground-support missions through the end of the war. It received Distinguished Unit Citations for sustained operations, including a period in 1950–1951 and a major effort during the enemy spring offensive in 1951. The group remained in Korea after the armistice and supported later regional commitments, including operations connected with the evacuation of the Tachen Islands in 1955. The historic group was inactivated on 1 October 1957. Its lineage was revived as the 18th Tactical Fighter Group in 1978 for Western Pacific training and operations, but that organization was inactivated in 1981. On 1 October 1991, following the 18th Wing's adoption of the objective-wing structure, the 18th Operations Group was activated. The new group consolidated the wing's operational squadrons and reflected the wing's transformation into a composite organization with multiple mission types. At Kadena Air Base, the modern group oversees or supports fighter, rescue, refueling, airborne command-and-control, air-control, aeromedical evacuation, operations-support and expeditionary reconnaissance units. Listed components include the 44th and 67th Fighter Squadrons, 31st and 33d Rescue Squadrons, 909th Air Refueling Squadron, 961st Airborne Air Control Squadron, 623d Air Control Squadron, 18th Aeromedical Evacuation Squadron, 18th Operations Support Squadron and 319th Expeditionary Reconnaissance Squadron. Aircraft and systems associated with these units include the F-15, HH-60W, KC-135R, E-3 and MQ-9. The group continues to function as the operational flying component of the 18th Wing.
