Overview
The 7th Operations Group is a United States Air Force operational unit assigned to the 7th Bomb Wing at Dyess Air Force Base, Texas. It is not a commercial consumer brand, but a military organizational identity and lineage-bearing unit. Its principal present-day role is to organize, train, and employ the wing's bomber crews and associated operational-support personnel. The group currently operates the Rockwell B-1B Lancer and carries the tail-code identity associated with the 7th Bomb Wing. The group's institutional lineage reaches back to the First Army Observation Group, organized in France on 6 September 1918 during the First World War. That predecessor conducted visual and photographic reconnaissance over German-held territory, documenting troop movements, transport routes, rail facilities, artillery positions, airfields, and supply installations. It flew hundreds of successful missions and continued alert operations after the Armistice. The lineage was subsequently reorganized in the United States and redesignated as the 7th Observation Group in 1921, although that formation was inactivated later the same year for funding reasons. A successor organization was activated at Rockwell Field, California, in 1928. During the interwar period it evolved from observation work into bombardment training and operated aircraft including the Curtiss B-2 Condor, Keystone B-4, Martin B-12, and other period types. The unit participated in Army exercises, aerial reviews, atmospheric experiments, and humanitarian supply drops. It also took part in the Army Air Corps' temporary domestic air-mail operation in 1934. Transfers to March Field, Hamilton Field, and Fort Douglas reflected changing basing requirements and the introduction of larger and more capable bombers, including the B-17 Flying Fortress. The 7th Bombardment Group was moving toward the Philippines when Japan attacked Pearl Harbor on 7 December 1941. Six of its B-17 aircraft reached Hawaii during the attack but avoided destruction by landing at alternate fields. Other elements were diverted to Australia, Java, India, and surrounding theaters. In the Southwest Pacific and China-Burma-India theaters, the group operated B-17s, B-24 Liberators, B-25 Mitchells, and LB-30 aircraft against Japanese airfields, shipping, bridges, railways, fuel and supply facilities, troop concentrations, and industrial targets. It received two Distinguished Unit Citations, including recognition for an attack on rail lines and bridges in Thailand in March 1945. Near the end of the war, it supported air transport operations over the Himalayan route known as The Hump. After returning to the United States, the group was reactivated in 1946 as a Strategic Air Command bombardment unit equipped initially with B-29 Superfortresses. It later transitioned to B-36 Peacemakers and supported long-range strategic-bombardment training, overseas deployments, and demonstrations of global reach. Its aircraft participated in major long-distance flights, including missions to Europe and Japan, and helped establish the 7th Bomb Wing's Cold War deterrence role. The group was inactivated in 1952 when the wing adopted the Tri-Deputate structure and its flying squadrons were assigned directly to the wing. The unit returned in 1991 as the 7th Operations Group under the Air Force Objective Wing organization. In its modern form, it serves as the flying component of the 7th Wing and oversees operational and training functions for the wing's bomber force. Its subordinate structure includes the 7th Operations Support Squadron, 9th Bomb Squadron, 28th Bomb Squadron, and 436th Training Squadron. The group's identity therefore combines current B-1B operational responsibilities with a lineage extending through reconnaissance, conventional bombardment, strategic deterrence, and combat-support missions across more than a century.
History
The 7th Operations Group descends from the First Army Observation Group, organized at Gondreville-sur-Moselle Aerodrome in France on 6 September 1918. Its early mission was battlefield observation for the First Army. Aircraft conducted day and night patrols, photography, mapping, and surveillance of German roads, railways, artillery, depots, airfields, and troop movements. During the Saint-Mihiel campaign and subsequent operations, the group flew 1,271 sorties and engaged in repeated aerial combat before the November 1918 Armistice. Following the war, the organization was recreated in the United States as the 1st Army Observation Group and redesignated the 7th Observation Group on 14 March 1921. It was inactivated later that year because of budget constraints. A new 7th group was activated at Rockwell Field, California, on 1 June 1928, with bombardment squadrons assigned. During the 1930s it helped develop Army Air Corps operational methods, including radio-directed interception exercises, large-scale maneuvers, aerial demonstrations, atmospheric experiments, and emergency delivery of food and medical supplies. Its aircraft included Curtiss, Keystone, Martin, and other interwar bomber types. The group moved to March Field in 1931 and later to Hamilton Field in 1937. As heavier bombers entered service, it received B-18 Bolos and then B-17 Flying Fortresses. In 1940 it moved to Fort Douglas near Salt Lake City, where the airfield could better accommodate the new aircraft. The unit was preparing to deploy to the Philippines when the Pearl Harbor attack disrupted the movement. Six B-17s arrived in Hawaii during the attack and landed safely at alternate airfields. The ground echelon was diverted to Australia, while the air echelon moved through the Middle East and India toward the Pacific. From Java and other locations, the group attacked Japanese forces and installations in the Philippines and the Netherlands East Indies. After regrouping in India in 1942, it converted to longer-range aircraft and operated under the Tenth Air Force against targets in Burma, Thailand, China, and the Andaman Sea. It attacked transport networks, refineries, bridges, warehouses, ports, airfields, shipping, and troop concentrations. It earned two Distinguished Unit Citations and ended its bombing role in 1945, later carrying fuel from India to China over the Himalayan route. The group returned to the United States in December 1945 and was inactivated the following month. The organization was activated again on 1 October 1946 as a Strategic Air Command bombardment group. It initially flew B-29 Superfortresses and conducted global bombardment training, overseas deployments, and long-range demonstrations. In 1948 it transitioned to B-36 Peacemakers, becoming part of the early Cold War strategic deterrent force. Its operations included flights to Japan, Europe, and the United Kingdom, demonstrating the ability of heavy bombers to deploy and operate over intercontinental distances. The group became inactive in 1952 after the 7th Bomb Wing adopted the Tri-Deputate system and assigned its bombardment squadrons directly to the wing. The group was reactivated in 1991 as the 7th Operations Group when the Air Force implemented the Objective Wing structure. It again became the operational component of the 7th Wing. The modern group is stationed at Dyess Air Force Base and flies the B-1B Lancer. Its assigned elements include the 7th Operations Support Squadron, 9th Bomb Squadron, 28th Bomb Squadron, and 436th Training Squadron. The 9th and 28th Bomb Squadrons also preserve combat lineages reaching back to the First World War.
