The 19th Operations Group (19 OG) is the operational flying component of the United States Air Force 19th Airlift Wing, stationed at Little Rock Air Force Base, Arkansas.Equipped with the Lockheed C-130 Hercules, the group provides part of Air Mobility Command's Global Reach capability. Tasking requirements range from supplying humanitarian airlift relief to victims of disasters, to airdropping supplies and troops into the heart of contingency operations in hostile areas.

The 19 OG is one of the oldest organizations in the Air Force, being a successor organization of the 19th Bombardment Group, one of the 15 original combat air groups formed by the Army before World War II.

As part of the Far East Air Force, the unit was stationed at Clark Field in the Philippines when the Japanese attacked on 8 December 1941, suffering numerous casualties and losing most of its Boeing B-17 Flying Fortresses in the attack. A small number of its aircraft escaped to fly combat missions in the Philippines; Netherlands East Indies and Papua New Guinea during early 1942.In March 1942, the group was re-established in Australia, as part of the Fifth Air Force. From far-flung bases in Queensland, the Northern Territory and Western Australia, the group carried out missions over Japanese-held areas in New Guinea and the Dutch East Indies.

After moving to Guam in 1944, the group was re-equipped with the Boeing B-29 Superfortress and conducted its first raid with B-29s on 25 February 1945, against Tokyo.The group has earned the distinction of being one of the most decorated units in the Air Force. Unit honors include nine Presidential Unit Citations, two Air Force Meritorious Unit Awards, ten Air Force Outstanding Unit Awards, one Philippine Presidential Unit Citation, and one Republic of Korea Presidential Unit Citation.
