374th Operations Group
The 374th Operations Group (374 OG) is the operational flying component of the United States Air Force 374th Airlift Wing. It is stationed at Yokota Air Base, Japan.

The unit's World War II predecessor unit, the 374th Troop Carrier Group operated primarily in the Southwest Pacific Theater, being formed in Australia in 1942 using resources from the Air Carrier Service (formerly Air Transport Command). The group employed a large variety of aircraft to perform air transport of troops, cargo, and evacuation of the wounded, earning two United States Distinguished Unit Citations (DUCs) in Papua New Guinea. In January–February 1943, the group supplied Allied forces during the battle of Wau airstrip, making landings at the airstrip under enemy fire and earning its third DUC. When the Korean War broke out in June 1950, was the only air transport group in the Far East. During the Cold War, the group airlifted wounded French troops from Indo-China to Japan, en route to France. Inactivated in 1958, the group was reactivated in 1966 at Naha AB, Okinawa as part of 315th Air Division and was active in the Vietnam War. Since that time its assigned squadrons have conducted special operations, aeromedical evacuations, search and rescue operations, humanitarian relief and theater airlift missions in support of US and United Nations security interests throughout the Far East.

The group has never been assigned to the United States.

Overview
The 374 OG maintains a forward presence by providing rapid responsive movement of personnel, equipment and operational support in the Asia-Pacific region. Ensures the combat readiness of three operational squadrons using C-130J, C-12J and UH-1N aircraft. Conducts three distinct missions; intratheater airlift, aeromedical evacuation and distinguished visitor transport for U.S. Pacific Command and other agencies in support of national security policy.

The unit consists of the following squadrons:
 36th Airlift Squadron  C-130J (Tail Code: YJ)

History

The 374th Troop Carrier Group drew its resources from the Air Carrier Service (formerly Air Transport Command) Allied Air Forces, Southwest Pacific Area when it formed in November 1942. It had four troop carrier squadrons assigned, the 21st and 22d were veterans of the South Pacific Area. During the remainder of 1942 and early 1943, the group employed a large variety of aircraft to perform air transport of troops, cargo, and evacuation of the wounded, earning two Distinguished Unit Citations (DUCs) in Papua. In January–February 1943, the group supplied Allied forces during the battle of Wau airstrip, making landings at the airstrip under enemy fire and earning its third DUC. From mid-Feb to July 1943, the group transported personnel and supplies to three principal areas: Dobodura, where a large base was being constructed; Wau and Bulolo, rear bases for advancing Allied forces; and to patrols skirting Lae and Salamau.

During Jul and August 1943, the group trained elements of the 375th, 403d, and 433d Troop Carrier Groups. When the campaign against Lae opened on 5 September 1943, the 374th led aircraft of those groups in a drop of US airborne troops and Australian artillery paratroops at Nadzab airdrome. The next day, as vegetation around the captured airdrome still burned, the group landed engineer troops and equipment to repair the damaged runways, and artillery to protect the captured airstrip. After the capture of Lae ten days later, the group flew 303 trips moving large stores of ammo, supplies, and equipment for use of advancing ground troops. From October 1943 – May 1944, the 374th maintained an unending flow of troops and equipment, including arms and ammunition, to units scattered throughout Australia and New Guinea areas. It continued to provide these services and in November 1944 commenced cargo and personnel flights to Leyte in the Philippines, which required three days for a round trip. By January 1945, flights in the New Guinea and Australian areas continued, but flights to the Philippines almost ceased until the group moved to Nielson Field near Manila and remained until the end of the war.

The group participated in training maneuvers with army and naval forces in the Pacific Theater until May 1946. From October 1946 – April 1947, it provided troop carrier and air courier services and participated in joint maneuvers in the Pacific.

It moved to Japan in March 1949 and when the Korean War broke out in June 1950, was the only air transport group in the Far East. For its work between 27 June and 15 September 1950, transporting vital cargo, personnel and evacuating wounded men, the 374th earned its fourth DUC. In April 1953, the group transported the first of several groups of repatriated prisoners of war from Korea to Japan.

Beginning in January 1954, the 374th airlifted wounded French troops from Indo-China to Japan, en route to France. Principal operations from 1955 until 1958 consisted of numerous mobility exercises, routine theater airlift, and occasional exercises throughout the Western Pacific region.

Activated as an Operations Group under the objective wing structure in April 1992, the group gained control over the 374th Airlift Wing's operational squadrons. From 1992 to present, the 374th Operation Group's assigned squadrons conducted special operations, aeromedical evacuations, search and rescue operations, humanitarian relief and theater airlift missions in support of US and UN security interests throughout the Far East.
