Overview

The 459th Operations Group is a reserve component of the United States Air Force assigned to the 459th Air Refueling Wing at Joint Base Andrews, Maryland. The wing belongs to Fourth Air Force within Air Force Reserve Command; if mobilized, it is gained by Air Mobility Command. The group is a military organization rather than a commercial consumer brand. Its role is to recruit, train, and equip citizen airmen who operate and support Boeing KC-135 Stratotanker air-refueling missions, helping extend the range and endurance of United States air and space forces. The organization traces its lineage to the 459th Bombardment Group, established during World War II. Activated in July 1943, the group trained with Consolidated B-24 Liberators before moving overseas to the Mediterranean theater. From bases in Italy it conducted long-range strategic bombing against military, industrial, transportation, petroleum, and airfield targets across Italy, France, Germany, Austria, Hungary, Romania, and Yugoslavia. It also performed interdiction and close-support activities, including attacks on rail networks supplying German forces around Anzio, and operations supporting the Allied invasion of southern France. In April 1944, the group led its bombardment wing in an attack on an airfield and aircraft factory at Bad Vöslau, Austria, under heavy antiaircraft fire and fighter opposition, earning a Distinguished Unit Citation. It flew nearly 200 combat missions before ending combat operations in April 1945. After returning to the United States, it was inactivated in August 1945 following Japan's surrender. The lineage continued through several Air Force Reserve incarnations. The group was reactivated in 1947 and initially trained with lighter aircraft while reserve structures were reorganized. It was mobilized during the Korean War in 1951, after which its personnel were distributed among other units and the group was inactivated. In 1955 it returned at Andrews Air Force Base as the 459th Troop Carrier Group, operating Curtiss C-46 Commandos and later Fairchild C-119 Flying Boxcars. Its reserve activities included Operation Sixteen Ton, which moved Coast Guard equipment to destinations in the Caribbean and the Bahamas, as well as high-priority cargo and aircraft-engine transport under Operation Swift Lift and Operation Ready Swap. The group was inactivated in 1959 during an Air Force organizational reconfiguration. The present operations-group designation was created in 1992 as part of the Air Force's Objective Wing reorganization. Initially equipped with Lockheed C-141B Starlifters, the reactivated group supported contingency and humanitarian airlift, Air Mobility Command channel missions, aeromedical evacuation, training exercises, and deployments of other military units. From October 2001 through September 2003 it supported intertheater airlift connected with Operation Enduring Freedom and Operation Iraqi Freedom. In 2003 its principal mission shifted from airlift to air refueling, and its C-141 aircraft were replaced by Boeing KC-135R Stratotankers. The group subsequently provided aircraft and crews for Operation Iraqi Freedom in 2005 and expanded its role in global air-refueling operations. Its current operational components include the 756th Air Refueling Squadron, the 459th Aeromedical Evacuation Squadron, and the 459th Operations Support Flight.

History

The 459th Operations Group's lineage began with the 459th Bombardment Group, which was established on 19 May 1943 and activated on 1 July 1943 at Alamogordo Army Air Field, New Mexico. Its original squadrons were the 756th, 757th, 758th, and 759th Bombardment Squadrons. The group trained on Consolidated B-24 Liberators under Second Air Force and moved to Westover Field, Massachusetts, in October 1943. Before its overseas deployment, it flew long-range convoy-escort missions over the waters between the Newfoundland Banks and Long Island Sound. The group reached Italy in February 1944 and began combat operations the following month. Its main mission was long-range strategic bombing against enemy military and industrial infrastructure. Targets included railroad marshalling yards, oil refineries, airfields, heavy-industry facilities, bridges, harbors, and troop concentrations in several occupied and Axis-aligned areas of Europe. The group participated in attacks supporting the Anzio campaign and Operation Dragoon, and later struck communications and transportation targets to assist Allied ground forces advancing through northern Italy. In April 1944 it led the 304th Bombardment Wing in an attack on the airfield and aircraft factory at Bad Vöslau, Austria. The action took place in the face of intense flak and fighter resistance and resulted in a Distinguished Unit Citation. The group completed almost 200 combat missions before ending operations in April 1945. After returning to the United States in August 1945, the group was considered for strategic operations against Japan using Boeing B-29 Superfortresses. Japan's surrender ended that requirement, and the unit was inactivated on 28 August 1945. It was redesignated the 459th Bombardment Group, Very Heavy, in March 1947 and reactivated in the Air Force Reserve at Long Beach Army Air Field in April of that year. The reserve organization underwent repeated changes as the Air Force adjusted its postwar structure. It trained with North American T-6 Texans and several Beechcraft training aircraft, and its units were distributed between Long Beach and Davis–Monthan Field. Budget reductions and the Air Force's adoption of corollary arrangements altered the group's status in 1949. Some of its elements were associated with Strategic Air Command units, allowing reservists to train alongside active-duty personnel. The group and related corollary units were mobilized for the Korean War in May 1951. Its personnel were reassigned to other organizations, and the group was inactivated on 16 June 1951. The reserve mission returned at Andrews Air Force Base in 1954, where the 756th Troop Carrier Squadron operated Curtiss C-46 Commandos. The group was reactivated as the 459th Troop Carrier Group in January 1955. During this period the Air Force placed reserve squadrons at separate operating locations to improve recruiting and make smaller units easier for local communities to support. The group participated in Operation Sixteen Ton in 1956, moving Coast Guard equipment from Floyd Bennett Naval Air Station to Puerto Rico and the Bahamas. It also used reserve training periods for Operation Swift Lift, carrying priority cargo, and Operation Ready Swap, transporting aircraft engines between Air Materiel Command depots. The 757th and 758th Troop Carrier Squadrons later operated Fairchild C-119 Flying Boxcars, while the 756th transitioned from the C-46. The group was inactivated in April 1959 during the adoption of a dual-deputy wing organization. The unit was redesignated the 459th Tactical Airlift Group in 1985 but remained inactive. On 1 August 1992 it was redesignated and reactivated as the 459th Operations Group under the Air Force Reserve's Objective Wing model. Equipped with C-141B Starlifters, it performed contingency and humanitarian airlift, Air Mobility Command channel flights, aeromedical evacuation, exercises, and support for the deployment of other units. From 2001 to 2003 it supported intertheater airlift for operations in Afghanistan and Iraq. In 2003 the group converted from airlift to air refueling and began operating Boeing KC-135R Stratotankers. The 459th Operations Group remains assigned to the 459th Air Refueling Wing and provides reserve air-refueling, aeromedical-evacuation, and operational-support capabilities.
