The 375th Operations Group (375 OG) is the operational flying component of the United States Air Force 375th Air Mobility Wing. It is stationed at Scott Air Force Base, Illinois.

The unit's World War II predecessor unit, the 375th Troop Carrier Group operated primarily in the Southwest Pacific Theater transporting men, supplies and ammunition to forward bases in New Guinea, New Britain and in the Solomon and Admiralty Islands. In 1943, the unit took part in the first airborne operation in the Southwest Pacific, dropping paratroops to seize enemy bases and cut overland supply lines in New Guinea. It was awarded the Philippine Presidential Unit Citation for its role in the liberation of the Philippines during 1944–1945. After the war, the unit served in the reserves and was elevated to active service during the Korean War. It returned to reserve duty until its inactivation in 1957; then again since 1991 after its reactivation.


The 375 OG comprises four airlift squadrons, a tanker squadron, an Operations Support Squadron, an Aeromedical Evacuation Squadron, and an Expeditionary Aeromedical Evacuation Flight. They provide operational airlift support with 20 C-21A aircraft, DV special airlift missions utilizing three C-40C aircraft, and operate Aeromedical Evacuation systems on seven air mobility platforms for inter/intratheater casualty movement. Responsible for C-21A aircraft maintenance, joint-use airfield services, and operations support for deployment of combat-ready aircrews and aircraft worldwide.

Collectively operate 20 C-21A aircraft out of three geographically separated locations including Scott AFB, Ill, Andrews AFB, Maryland, and Peterson AFB, Colorado. They provide Operational Support Airlift and Aeromedical Evacuation.
Partners with the 932d Airlift Wing as one of the first-ever AMC/AFRC active associate squadrons under the Total Force Integration model. The squadron flies four specially configured C-40C aircraft on Special Air Missions as directed by HQ USAF to transport members of the Presidential Cabinet and Congress, foreign heads of state, and other dignitaries.
