The unit began during World War II when the United States Army Air Forces activated the 462d Bombardment Group as one of the first Boeing B-29 Superfortress units in 1943. It served in the Pacific Ocean theater and China Burma India Theater of World War II as part of Twentieth Air Force. The 462d engaged in strategic bombing campaign against Japan. The group earned three Distinguished Unit Citations. It returned to the United States in November 1945 and was inactivated in March 1946.

In 1962 the 462d Strategic Aerospace Wing was activated by Strategic Air Command (SAC) to perpetuate the lineage of inactive bombardment units with illustrious World War II records. It conducted strategic bombardment training operations flying Boeing B-52D Stratofortresses and maintained intercontinental ballistic missile readiness with LGM-25 Titan I missiles to meet SAC commitments. The wing served as a deterrent force and also supported SAC's global mission until inactivated in 1966 due to the closing of Larson Air Force Base.

The group and wing were consolidated into a single unit in 1984, remaining in inactive status. In 2002, the consolidated unit was converted to provisional status as the 462d Air Expeditionary Group and assigned to Air Mobility Command, which activated the group at Diego Garcia. Its inactivation date has not been determined.


World War IIEdit

Training in the United StatesEdit

B-29s of the 462d at West Field Tinian 1945

The 462d Bombardment Group was constituted on 15 May 1943 as a Boeing B-29 Superfortress group and activated on 1 July at Smoky Hill Army Air Field near Salinas, Kansas. It was originally assigned the 768th,[3] 769th,[4] 770th,[4] and 771st Bombardment Squadrons.[5][6] On 28 July it moved to Walker Army Air Field in Kansas where the group engaged in training on the new aircraft and its new mission. The 462d was assigned to the first Superfortress wing, the 58th Bombardment Wing.[7]

Operations from India and ChinaEdit

In March 1944, the group left the United States and deployed via Africa to Piardoba Airfield, a former B-24 Liberator airfield at India, arriving on 7 April in India, the group was assigned to the XX Bomber Command of the new Twentieth Air Force. During the week of 15–22 April, no fewer than five 58th Bomb Wing B-29s crashed near Karachi all from overheated engines. The entire wing had to be grounded en route until the cause was found. The cause was traced to the fact that the B-29's R-3350 engine had not been designed to operate at ground temperatures higher than 115 °F (46 °C), which were typically exceeded in India. Modifications had also to be made to the aircraft and after these modifications, B-29 flights to India were resumed.[citation needed]

From India, the 462d Bomb Group planned to fly missions against Japan from airfields in China. However, all the supplies of fuel, bombs, and spares needed to support the forward bases in China had to be flown in from India over The Hump (the name given by Allied pilots to the eastern end of the Himalayan Mountains), since Japanese control of the seas around the Chinese coast made seaborne supply of China impossible. Many of the supplies had to be delivered to China by the B-29s themselves.[6] For this role, they were stripped of nearly all combat equipment and used as flying tankers and each carried seven tons of fuel. The Hump route was so dangerous and difficult that each time a B-29 flew from India to China it was counted as a combat mission.[citation needed]

The first combat mission by the group took place on 5 June 1944 when squadrons of the 462d took off from India to attack the Makasan railroad yards at Bangkok, Thailand.[6] This involved a 2261-mile round trip, the longest bombing mission yet attempted during the war.

On 15 June the group participated in the first American Air Force attack on the Japanese Home Islands since the Doolittle raid in 1942 when it took part in the bombing of Yawata.[6] Operating from bases in India, and at times staging through fields in India and China, the group struck transportation centers, naval installations, iron works, aircraft plants, and other targets in Japan, Thailand, Burma, China, Formosa, and Indonesia.[6] From a staging base in Ceylon, the 462d mined the Musi River in Sumatra in August 1944. The 462d received a Distinguished Unit Citation (DUC) for a nighttime attack on iron and steel works at Yawata, Japan, on 20 August 1944.[6] In October 1944, Twentieth Air Force reorganized its B-29 units. As a result, the 462d lost its 771st Bombardment Squadron[5] and its four Bombardment Maintenance Squadrons, absorbing their personnel into its remaining squadrons.

Operations from the Marianas and return homeEdit

The group moved to West Field (Tinian), in the Marianas between February and April 1945, for further operations against Japan with the XXI Bomber Command. It participated in mining operations, bombardment of strategic targets, and incendiary raids on urban areas. It bombed industrial areas in Tokyo and Yokohama in May 1945, being awarded a DUC for the action. The group received a third Distinguished Unit Citation for a daylight attack on an aircraft plant at Takarazuka on 24 July 1945.[6]

The 462d returned to the United States, arriving at MacDill Field, Florida in November 1945. Demobilization, however, was in full swing and the group turned in its aircraft and was inactivated on 31 March 1946, never becoming an operational SAC unit.[6] Many of the wing's personnel and aircraft were reassigned to the 307th Bombardment Group, which was activated at MacDill on 4 August 1946 as part of the re-established Fifteenth Air Force.

Strategic Air CommandEdit

4170th Strategic WingEdit

The origins of the 462d Strategic Aerospace Wing date to 1 August 1958 when Strategic Air Command (SAC) established the 4170th Strategic Wing at Larson Air Force Base, Washington and assigned it to the 18th Air Division (later 18th Strategic Aerospace Division)[8] as part of SAC's plan to disperse its Boeing B-52 Stratofortress strategic bombers over a larger number of bases, thus making it more difficult for the Soviet Union to knock out the entire fleet with a surprise first strike.[9] The wing remained a headquarters only until 1 December 1959 when the 47th Aviation Depot Squadron and a combat defense squadron were activated to oversee and guard the wing's special weapons.

In January 1960, in anticipation of the 62d Troop Carrier Wing of Military Air Transport Service (MATS)'s impending move to McChord Air Force Base from Larson,[10] MATS transferred Larson to SAC and the 4170th acquired a full set of support units, including the 829th Medical Group. In June, it added its first operational squadron, when the 327th Bombardment Squadron, consisting of 15 Boeing B-52 Stratofortresses moved to Larson from Fairchild Air Force Base, where it had been one of the three squadrons of the 92d Bombardment Wing.[11] The wing became fully organized on 15 November 1960 when the 43d Air Refueling Squadron moved to Larson from Davis–Monthan Air Force Base, Arizona and re-equipped with Boeing KC-135 Stratotankers. One third of the wing's aircraft were maintained on fifteen-minute alert, fully fueled, armed and ready for combat to reduce vulnerability to a Soviet missile strike. The wing's final operational squadron, the 568th Strategic Missile Squadron with SM-68 Titan I missiles, was activated in April 1961.[12] The wing's aircraft alert commitment was increased to half the wing's aircraft in 1962.[13] The 4170th (and later the 462d) continued to maintain an alert commitment until April 1966.[1]

SAC responded to the Cuban Missile Crisis shortly after the detection of Soviet missiles on Cuba. On 20 October the wing was directed to put two additional bombers on alert . On 22 October 1/8 of SAC's B-52s were placed on airborne alert and additional KC-135 were placed on alert to replace tankers devoted to maintaining the B-52 bomber force on airborne alert. On 24 October SAC went to DEFCON 2, placing all aircraft on alert.[14] The wing supported the increase in forward deployed Tanker Task Forces were in Spain, Alaska and in the Northeast.[15] On 21 November, due to the strains on its maintenance and flying crews, SAC returned to its normal airborne alert posture.[16] It also relaxed its readiness staus to DEFCON 3 and on 27 November the wing returned to normal alert posture.[17]

462d Strategic Aerospace WingEdit

In 1962, in order to perpetuate the lineage of many currently inactive bombardment units with illustrious World War II records, Headquarters SAC received authority from Headquarters USAF to discontinue its Major Command controlled (MAJCON) strategic wings that were equipped with combat aircraft and to activate Air Force controlled (AFCON) units, most of which were inactive at the time, but could carry a lineage and history.[note 2] As a result, the 4170th wing was replaced by the newly constituted 462d Strategic Aerospace Wing, which assumed its mission, personnel, and equipment on 1 February 1963.[note 3] The 768th Bombardment Squadron, one of the unit's World War II historical bomb squadrons, replaced the 327th Bombardment Squadron, which was inactivated.[3][11] The 829th Medical Group, 47th Munitions Maintenance Squadron and the 43d Air Refueling Squadron were reassigned to the 462d. Component support units of the 4170th Wing were replaced by units with numerical designation of the newly established 462d Wing. Each of the new units assumed the personnel, equipment, and mission of its predecessor. Under the Dual Deputate organization, all flying and maintenance squadrons were directly assigned to the wing, so no operational group element was activated.[note 4]

The 462d Wing conducted training in strategic bombardment and air refueling operations and maintained intercontinental ballistic missile readiness to meet SAC commitments. Its 568th Strategic Missile Squadron served as a deterrent force until inactivating in March 1965.[1] However, "[i]n December 1965, . . . Robert S. McNamara, Secretary of Defense [announced] another phaseout program that would further reduce SAC’s bomber force. Basically, this program called for . . . retirement of all B-52Cs and of several subsequent B-52 models."[18] The wing became non-operational in April 1966, and was inactivated on 25 June 1966 with the closing of Larson.[1]

Expeditionary operationsEdit

In June 2002, the consolidated unit was converted to provisional status and assigned to Air Mobility Command to activate or inactivate as needed.[7] It was activated a few days later at the Naval Support Facility Diego Garcia, where it controlled KC-135R tankers deployed to support Operation Enduring Freedom.
