The 18th Operations Group is the operational flying component of the United States Air Force 18th Wing, stationed at Kadena Air Base, Okinawa, Japan.

The 18th OG is the largest combat operations group in the Air Force with eight squadrons, one flight, 842 active-duty members and approximately 80 aircraft, including the F-15 Eagle, E-3 Sentry, KC-135 Stratotanker and the HH-60 Pave Hawk.

The group is one of the oldest in the United States Air Force, being a successor organization of the 18th Pursuit Group, one of the 15 original combat air groups formed by the Army before World War II.

The group's nine squadrons (Tail Code: ZZ) and flight include:

• 18th Aeromedical Evacuation Squadron (AES)
• 18th Operations Support Squadron (OSS)
• 44th Fighter Squadron (FS) (F-15 Eagle)
• 67th Fighter Squadron (FS) (F-15 Eagle)
• 31st Rescue Squadron (RQS)
• 33d Rescue Squadron (RQS) (HH-60G Pave Hawk)
• 623d Air Control Flight (ACF)
• 909th Air Refueling Squadron (ARS) (KC-135R Stratotanker)
• 961st Airborne Air Control Squadron (AACS) (E-3 Sentry)

The 18th Wing has the unique distinction of being the only wing never stationed in the Continental United States. 18th Wing heritage began on 21 January 1927, when the War Department activated a provisional pursuit group at Wheeler Field, Hawaii. Shortly thereafter the group was re-designated the 18th Pursuit Group with the following squadrons:

• 6th Pursuit Squadron (assigned January 1927)
• 19th Pursuit Squadron (assigned January 1927)

The "fighting cock" Group insignia with "Unguibus et Rostro", "With Talon and Beak" was chosen by 18th Pursuit Group CO Maj. Carlyle H. Walsh in February 1931, and officially approved in 1932. Major Kenneth M. Walker (for whom Walker AFB, New Mexico was later named) assumed command in March 1940, having on his staff Captain Roger W. Ramey (for whom Ramey AFB Puerto Rico was named), and Lieutenants Bruce K. Holloway, K. P. Bocquist, John G. Simpson, and William F. Savidge.

The Group was flying Boeing P-26 Peashooters, then upgraded into the radial-engined Curtiss P-36 Hawks before being re-equipped with Curtiss P-40s a few months prior to the attack on Pearl Harbor by Japanese naval aircraft which immediately drew the United States into World War II.

In the immediate months before the Pearl Harbor attack, the group was expanded as follows:

• 6th Pursuit Squadron (Interceptor) (P-40B)
• 19th Pursuit Squadron (Interceptor) (P-40B, P-40C)
• 44th Pursuit Squadron (Interceptor) (P-40B, P-40C) (At Bellows Field)
• 72nd Pursuit Squadron (Interceptor) (none)
• 73rd Pursuit Squadron (Interceptor) (P-40B)
• 78th Pursuit Squadron (Interceptor) (P-40B)

The Imperial Japanese attack on 7 December 1941, severely hurt the group – its only two P-40C Warhawks of the 44th Pursuit Squadron to get airborne were immediately shot down, and the rest of the group's aircraft were heavily damaged. Over 60 P-40Cs were destroyed on the ground at Wheeler. The group, assigned to Seventh Air Force in February 1942, had to be re-equipped before it could resume training and begin patrol missions.

During March 1943, the group moved to the South Pacific Theater and rejoined the war effort as part of Thirteenth Air Force and began operations from Guadalcanal. Flew protective patrols over US bases in the Solomons; later, escorted bombers to the Bismarcks, supported ground forces on Bougainville, and attacked enemy airfields and installations in the northern Solomons and New Britain. Used Lockheed P-38 Lightnings; Bell P-39 Airacobra; Northrop P-61 Black Widows, and Douglas P-70 Havoc aircraft. The following operational squadrons were assigned to the 18th Fighter Group:

• 6th Night Fighter Squadron (P-70)
• 12th Fighter Squadron (P-39)
• 44th Fighter Squadron (P-38)
• 70th Fighter Squadron (P-39)
• 419th Night Fighter Squadron (P-38,P-61)

The 18th FG moved to New Guinea in August 1944 equipped with P-38s. Escorted bombers to targets in the southern Philippines and Borneo, and attacked enemy airfields and installations in the Netherlands Indies. Received a Distinguished Unit Citation for actions at Ormoc Bay: on 10 November 1944 the group withstood intense flak and vigorous opposition from enemy interceptors to attack a Japanese convoy that was attempting to bring in additional troops for use against American forces that had landed on Leyte; on the following day a few of the group's planes returned to the same area, engaged a large force of enemy fighters, and destroyed a number of them.

Moved to the Philippines in January 1945. Supported ground forces on Luzon and Borneo, attacked shipping in the central Philippines, covered landings on Palawan, attacked airfields and railways on Formosa, and escorted bombers to such widely scattered targets as Borneo, French Indochina, and Formosa.

At the end of the war, the group moved to Clark Field on Luzon and became part of Far East Air Forces after the war. Flew patrols and trained with Lockheed F-80 Shooting Stars, with the distinction of being the first overseas fighter unit to be jet-equipped.

The group lost all personnel in March 1947 but was re-manned in September 1947. Equipped first with Republic F-47 Thunderbolts, later with North American F-51 Mustangs, and still later (1949) with F-80s.

In August 1948, it became a subordinate unit to the newly activated 18th Fighter Wing. On 20 January 1950, the wing was re-designated the 18th Fighter-Bomber Wing.

The 18th Fighter-Bomber Wing was reassigned to Korea in July 1950 and entered combat. Its organization was as follows:

• 12th Fighter-Bomber Squadron (F-80C, F-51D, F-86F)
• 67th Fighter-Bomber Squadron (F-80C, F-51D, F-86F)
• 39th Fighter Interceptor Squadron (March 1951 – March 1952) (F-51D)
• 2nd Squadron, South African Air Force (November 1950 – March 1951, April 1951 – June 1953) (F-51D)

At the outbreak of the Korean War, the 18th FBG's 12th FBS provided personnel to form the "Dallas" fighter squadron, which rushed into battle. In late July, the group headquarters with two of its squadrons (12th and 67th FBSs) deployed with F-80s from the Philippines to Taegu AB (K-2), South Korea.

From 28 July to 3 August, the 18th Group operated directly under Fifth Air Force then passed to the control of the 6002nd Fighter (later, Tactical Support) Wing. Pilots exchanged their F-80s for F-51 Mustangs. Combat targets included tanks and armored vehicles, locomotives and trucks, artillery and antiaircraft guns, fuel and ammunition dumps, warehouses and factories, and troop concentrations.

In August, advancing enemy forces and insufficient aircraft parking at Taegu forced the group to move to Japan, but it returned to South Korea the following month to support UN forces in a counteroffensive. Because the front advanced so rapidly, operations from Pusan (K-9) soon became impractical, and the group moved in November to Pyongyang East (K-24), North Korea. The 2nd SAAF Squadron joined the 18th in mid-November.

Maj Louis Sebille was posthumously awarded the Medal of Honor for his action on 5 August 1950: although his plane was badly damaged by flak while attacking a concentration of enemy trucks, Maj Sebille continued his strafing passes until he crashed into an armored vehicle.

The Chinese Communist (CCF intervention) caused the group to move twice in as many weeks, first to Suwon AB (K-13), South Korea, then to Chinhae (K-10). From there the 18th FBG continued to support ground forces and carry out armed reconnaissance and interdiction missions. From November 1950 through January 1951, it earned a Distinguished Unit Citation for destroying roughly 2,400 enemy vehicles and severely damaging almost 500 more.

From early 1951 until January 1953, the group and its tactical squadrons, moving from base to base in South Korea, operated separately from the rest of the 18th FBW. The group earned its second Distinguished Unit Citation from 22 April to 8 July 1951, when it flew 6,500 combat sorties while operating from sod, dirt filled, and damaged runways to counter the enemy's 1951 spring offensive.

When in January 1953 the group rejoined the wing at Osan-ni AB (K-55), its squadrons transitioned to F-86 Sabrejets without halting the fight against the enemy. It flew its first F-86 counter air mission on 26 February 1953. In the final days of the war, the 18th FBG attacked dispersed enemy aircraft at Sinuiju and Uiju Airfields.

The group remained in Korea for some time after the armistice.

In 1955, deployed to Formosa to support Nationalist Chinese evacuation of Tachen Islands. During subsequent active periods from 1978 to 1981 trained for air operations in western Pacific region

The designation of the wing changed on 1 October 1991 to the 18th Wing with the implementation of the Objective Wing concept. With the objective wing, the mission of the 18th expanded to the Composite Air Wing concept of multiple different wing missions with different aircraft. The operational squadrons of the wing were assigned to the 18th Operations Group.

The mission of the 18th OG was expanded to include aerial refueling with Boeing KC-135R/T Stratotanker tanker aircraft (909th ARS); and surveillance, warning, command and control Boeing E-3B/C Sentry (961st AACS), and communications. Added airlift mission in June 1992 with the Beech C-12 Huron, transporting mission critical personnel, high-priority cargo and distinguished visitors.

In February 1993, the 18th gained responsibility for coordinating rescue operations in the Western Pacific and Indian Ocean with the addition of the 33d Rescue Squadron (33d RQS).

In November 1999, the 18th underwent another change as one of its three F-15 units, the 12th Fighter Squadron, was reassigned to the 3d Wing at Elmendorf Air Force Base, Alaska.
