The 494th Air Expeditionary Group is a provisional United States Air Force assigned to Air Mobility Command (AMC) to activate or inactivate as needed. Although no unclassified sources indicate that AMC has activated the group, a patch published at USAF Patches.com implies that the group was active in Spain during Operation Iraqi Freedom.

The group was originally activated in 1943 as the 494th Bombardment Group. It was the last B-24 Liberator group formed by the United States Army Air Forces. The unit served primarily in Western Pacific, taking part in numerous campaigns. It earned the Philippine Presidential Unit Citation for its actions during the liberation of the Philippines.

It was then active during the Cold War as the 494th Bombardment Wing a Strategic Air Command unit, flying Boeing B-52 Stratofortress and Boeing KC-135 Stratotanker aircraft at Sheppard Air Force Base, Texas from 1962 1966.

World War II

The group was established in late 1943 as the 494th Bombardment Group, a Consolidated B-24 Liberator heavy bombardment group, and activated on 1 December at Wendover Field, Utah. Its initial squadrons were the 864th, 865th, 866th, and 867th Bombardment Squadrons (BS). The 494th was the last of seven heavy bombardment Groups – 488th through 494th – activated in the autumn of 1943, as B-29 Superfortress production was beginning in large numbers. The 494th was subsequently the last heavy bomb group formed and trained by the Army Air Forces.

The group's origins begin when the 10th Antisubmarine Squadron moved to Gowen Field, Idaho to retrain as a heavy bombardment unit with B-24s. At Gowen, the unit was renamed the 867th BS and moved to Wendover Field, Utah where it was joined by the newly activated 864th, 865th and 866th BS. The headquarters element of the group was formed from the staff of the 10th Antisubmarine Squadron. The group trained at Wendover until April when the base was converted by Second Air Force for B-29 training. It moved to Mountain Home Army Air Field, Idaho to complete its final phase of training. At Mountain Home, the group received new very long range B-24J aircraft in early May.

494th deployed to the Pacific Theater of Operations (PTO), initially at Barking Sands Army Airfield Hawaii. It flew from Idaho to Hamilton Field, California before its overseas movement. In Hawaii, the group received additional training in long range over ocean navigation while the ground echelon of the group transported by rail to Seattle, then by troop ship to Hawaii, arriving in mid-June. The unit remained in Hawaii throughout the summer of 1944 while its B-24s were modified at Hickam Field to meet the standards required by Seventh Air Force. Modifications were completed by 1 August, however the group was not deployed to the Southwest Pacific Area (SWPA) of operations until mid-September as its planned airfield on Angaur in the Palau Islands was not yet constructed due to ongoing combat on the island.

Aircraft were deployed from Hawaii on 10 October 1944, departing for Johnson Island, Kwajalein and Saipan. At Saipan, the unit was delayed a further 10 days due to combat ongoing in the Pelelieus. On Saipan, the 494th flew their first combat mission with crews of the 30th Bombardment Group, stationed on Saipan. The first elements of the 494th arrived on Angaur on 16 October, being strafed by Japanese forces still on the island as the battle of Bloody-Nose Ridge was still ongoing. As the area was finally secured in late October, additional aircraft began arriving; with the group completely established by the end of the month. The combat on the island had not allowed the construction of buildings and other support facilities, so the personnel of the group were engaged in construction activities upon their arrival.

The 494th entered combat on 3 November 1944 with attacks against Japanese airfields on Yap and Koror. Subsequently, the group engaged in very long range strategic bombing raids on other bypassed Japanese installations in the Pacific and against the Japanese in the Philippines. Late in 1944 the unit hit gun emplacements, personnel areas, ant storage depots on Corregidor and Caballo at the entrance to Manila Bay. It bombed radio installations and power plants at Japanese bases in the Philippines and attacked enemy-held airfields, including Clark Field on Luzon. Early in 1945 it struck airfields on Mindanao and ammunition and supply dumps in the Davao Gulf and Illana Bay areas.

The group moved to the newly built Yontan Airfield on Okinawa in June 1945. On Okinawa, the 373d Bombardment Squadron was assigned to the 494th from the CBI. From its new base, the group engaged primarily in very long range attacks against enemy airfields on Kyūshū. The group also participated in incendiary raids, dropped propaganda leaflets over urban areas of Kyūshū and struck airfields in China, in southern Korea, and around the Inland Sea of Japan until the Japanese capitulation in August.

After the war's end in September, the unit remained on Okinawa as older units began to demobilize. The group was engaged in transporting personnel and supplies in the Southwest Pacific, and moving necessary occupation support elements from Manila to Tokyo. It began to demobilize in November and December, with personnel returning to the United States. the 494th was inactivated as a paper unit in the United States on 4 January 1946.

4245th Strategic Wing

The origins of the 494th Bombardment Wing began on 5 January 1959 when Strategic Air Command (SAC) established the 4245th Strategic Wing as a tenant at Sheppard Air Force Base, Texas, an Air Training Command base and assigned it to the 816th Air Division (later 816th Strategic Aerospace Division) as part of SAC's plan to disperse its Boeing B-52 Stratofortress heavy 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. The wing remained a headquarters only until 1 August 1959, when the 61st Aviation Depot Squadron was activated to oversee the wing's special weapons. Two months later, three maintenance squadrons and a squadron to provide security for special weapons were activated and assigned to the wing.

The 4245th finally added its first operational squadron on 1 February 1960 when the 717th Bombardment Squadron (BS), consisting of 15 Boeing B-52 Stratofortresses moved to Sheppard from Ellsworth AFB, South Dakota where it had been one of the three squadrons of the 28th Bombardment Wing. The wing became fully operational on 1 October 1962 when the 900th Air Refueling Squadron, flying Boeing KC-135 Stratotankers, was organized and assigned to the wing. 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. This was increased to half the wing's aircraft in 1962. The 4245th (and later the 494th) continued to maintain an alert commitment until it was inactivated.

494th Bombardment Wing

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, which could carry a lineage and history.

As a result, the 4245th SW was replaced by the newly constituted 494th Bombardment Wing, Heavy (BW), which assumed its mission, personnel, and equipment on 1 February 1963. In the same way the 864th Bombardment Squadron, one of the unit's World War II historical bomb squadrons, replaced the 717th BS. The 61st Munitions Maintenance Squadron and the 900th Air Refueling Squadron were reassigned to the 494th. The 4245th's maintenance and security squadrons were replaced by ones with the 494th numerical designation of the newly established 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. The 494th Bomb Wing continued to conduct strategic bombardment training and air refueling operations to meet SAC's operational commitments.

By 1966, Intercontinental ballistic missiles (ICBM) had been deployed and become operational as part of the United States' strategic triad, and the need for B-52s had been reduced. In addition, funds were also needed to cover the costs of combat operations in Indochina. The 494th Bombardment Wing was inactivated on 1 April 1966 and its aircraft were reassigned to other SAC units.
