457th Airlift Squadron. The 457th Airlift Squadron was an executive airlift unit stationed at Andrews Air Force Base, Maryland.  It, and its predecessor, the 1402nd Military Airlift Squadron, operated a  number of executive aircraft starting in 1975.  From the mid-1990s, the squadron operated only Learjet C-21 aircraft.

The squadron's other predecessor was organized in 1942 as the 457th Bombardment Squadron, a heavy bomber training unit.  It was inactivated in the spring of 1944 when the Army Air Forces reorganized its training units on a more flexible basis.  The squadron was immediately activated as a Boeing B-29 Superfortress unit.  After training in the United States, it deployed to Guam, where it participated in the strategic bombing campaign against Japan, earning two Distinguished Unit Citations.  Following V-J Day it remained on Guam until November 1945, when it was inactivated.

The squadron was activated as a corollary unit in the reserve in 1949, serving alongside regular Strategic Air Command units at March Air Force Base.  It was mobilized as a result of the Korean War in 1951, but inactivated as its personnel were used to fully man other units.  When the reserve began to re-equip with aircraft in 1952, it was briefly activated as the 457th Troop Carrier Squadron, but transferred its personnel and equipment to another unit a month later.

It was organized again in 1967 when the Air Force took over de Havilland Canada C-7 Caribou operations from the Army.  It performed theater airlift missions in Viet Nam until inactivating in 1972 as the United States withdrew from Viet Nam.  It earned both Presidential Unit Citations and Air Force Outstanding Unit Awards with Combat "V" Device for its combat actions.

History

World War II

Bombardment training unit

The squadron was first activated at Salt Lake City Army Air Base, Utah on 6 July 1942 as one of the original four squadrons of the 330th Bombardment Group.  Although equipped early on with some Boeing B-17 Flying Fortresses, it became a Consolidated B-24 Liberator Operational Training Unit (OTU), moving to Biggs Field, Texas by early September.  The OTU program was patterned after the unit training system of the Royal Air Force and involved the use of an oversized parent unit to provide cadres to "satellite groups"    It then assumed responsibility for their training and oversaw their expansion with graduates of Army Air Forces Training Command schools to become effective combat units.  Phase I training concentrated on individual training in crewmember specialties.  Phase II training emphasized the coordination for the crew to act as a team. The final phase concentrated on operation as a unit.

By early 1944 most units had been activated and almost three quarters of them had deployed overseas.  With the exception of special programs, like forming Boeing B-29 Superfortress units, training “fillers” for existing units became more important than unit training.  The squadron then became a Replacement Training Unit (RTU).  RTUs were also oversized unit, but their mission was to train individual pilots or aircrews.

However, the Army Air Forces was finding that standard military units like the 457th, whose manning was based on relatively inflexible tables of organization were proving not well adapted to the training mission, even more so to the replacement mission.  Accordingly, the Army Air Forces adopted a more functional system in which each base was organized into a separate numbered unit.    As a result, the 330th Bombardment Group and its components, including the 457th, along with all supporting units at Biggs were inactivated or disbanded on 1 April 1944 and replaced by the 235th AAF Base Unit (Combat Crew Training School, Bombardment, Very Heavy).

B-29 Superfortress operations against Japan

The squadron was activated the same day at Walker Army Air Field, Kansas as a Boeing B-29 unit.  While waiting for new B-29s to come off the production line, it again flew B-17 Flying Fortresses for a short time.  It trained at Walker and at Dalhart Army Air Field, Texas until January 1945, when it deployed to the Pacific.

The squadron arrived at its combat station, North Field, Guam in the Mariana Islands in early February 1945.  Because the results of high altitude B-29 raids on Japan were disappointing.  XXI Bomber Command switched to low altitude night area attacks with incendiaries beginning in March 1945.  It flew its first combat mission, an attack on the Hodogaya chemical plant in Koriyama, Japan on 12 April 1945.

During April and May 1945, the squadron was diverted from the strategic campaign against Japan to support Operation Iceberg, the invasion of Okinawa.  It struck air bases from which kamikaze attacks were being launched.  Many of these bases were located on Kyushu, only 300 miles from Okinawa.  The attacks directly impacted kamikaze launches, but also forced the Japanese military to retain fighter aircraft to defend the Japanese Special Attack Units that otherwise might have been used to challenge air superiority over Okinawa.

The squadron resumed attacking urban industrial areas until the end of the war in August 1945.  It was awarded a Distinguished Unit Citation (DUC) for incendiary raids on the industrial sections of Tokushima and Gifu and a strike against the hydroelectrical power center at Kofu in July 1945.  It received a second DUC for a mission attacking the Nakajima Aircraft Company aircraft engine plant at Musashino near Tokyo in August.

Following V-J Day the squadron dropped food and supplies to Allied prisoners of war and participated in several show of force missions over Japan.  It departed the theater in November and was inactivated at Camp Anza, the Port of Embarkation in December 1945.

Air Force reserve
The May 1949 Air Force Reserve program called for a new type of unit, the Corollary unit, which was a reserve unit integrated with an active duty unit.  The plan called for corollary units at 107 locations.  It was viewed as the best method to train reservists by mixing them with an existing regular unit to perform duties alongside the regular unit.  As part of this program, the 457th was activated at March Air Force Base, California on 27 June 1949 as a corollary of ]Strategic Air Command (SAC)'s 22nd Bombardment Group, which was responsible for the 457th's training.  All reserve corollary units were mobilized for the Korean War.  The squadron was called to active duty on 1 May 1951.  The majority of its personnel were used to bring the 22nd to full strength and the squadron was inactivated on 16 June.

The reserve mobilization for the Korean War had left the reserve without aircraft.  In September 1951, Continental Air Command (ConAC) formed the 917th Reserve Training Wing to train reservists at Greater Pittsburgh Airport, Pennsylvania.  Anticipating the return of mission aircraft to reserve units, ConAC replaced the 917th Wing with the 330th Troop Carrier Wing on 14 June 1952.   The squadron was redesignated the 457th Troop Carrier Squadron and activated the same day.  It is not clear whether the squadron possessed its own aircraft or flew the Curtiss C-46 Commandos  of the 2253rd Air Force Reserve Training Center.  However, this activation was short lived, as the 330th was replaced by the 375th Troop Carrier Group, which was released from active duty on 14 July 1952, and which had been mobilized at Greater Pittsburgh in 1951.  The 457th was inactivated and transferred its personnel to the 55th Troop Carrier Squadron, which was simultaneously activated.

Theater airlift in Viet Nam

In August 1966, the Air Force and the Army began implementing Project Red Leaf, which would transfer responsibility for the de Havilland Canada C-7 Caribou from the Army to the Air Force following the Johnson-McConnell agreement of 1966.  At Can Tho and Soc Trang Airfields, South Vietnam, Air Force personnel began being assigned to the 134th Aviation Company.  The Department of Defense had ordered that the 483d Tactical Airlift Wing's new squadrons be located on Air Force installations, not on Army posts, and the cadre of the wing at Cam Ranh Bay Air Base began planning to move squadron level operations from the small Army camps they were operating from to permanent sites when the Air Force units were activated.  In December, the company began moving to Cam Ranh Bay Air Base, and on 1 January 1967, the 457th Squadron was organized and took over Caribou operations from the 134th Company.

The squadron provided intratheater airlift to support United States military civic actions, combat support and civic assistance throughout the Republic of Vietnam.  This included airland and airdrop assault missions.  It also maintained a detachment of two aircraft at Don Muang Air Base, Thailand.  In the summer of 1967, the 457th and its sister Caribou squadron at Cam Ranh Bay, the 458th Tactical Airlift Squadron took over Caribou operations at Pleiku Air Base, formerly operated by the 459th Tactical Airlift Squadron.   However, a Viet Cong mortar attack on Can Tho on 21 December 1967 that damaged two C-7s, forced a reevaluation of dispersal arrangements and Caribous were withdrawn from Pleiku. 

Most missions by the Caribou were airlift flights, with fewer than 2% being airdrops.  The squadron experienced an exception to this during the attempt by the North Vietnamese Army to overrun Duc Lap Camp, near the Cambodian border.  The camp was manned by half strength Civilian Irregular Defense Group companies, assisted by American special forces.  Duc Lap's landing strip was outside its defensive perimeter, and once Communist forces had surrounded the camp and occupied parts of it, airlanding resupplies was out of the question.  Airdrops were particularly difficult, as only about 75 square yards remained in friendly force possession.  The squadron's pilots approached the camp from random directions, flying at treetop level using strong evasive action due to heavy enemy fire, popping up and leveling off at the minimum altitude for parachutes to open only seconds before the drop was made.  The efforts included what is believed to have been the first operational night airdrop by a Caribou.  Between 24 and 26 August, C-7s delivered 26 tons of supplies to the besieged camp.  After the 26th, reinforcements expanded the area under friendly control and the brunt of further supply was borne by Army Boeing CH-47 Chinook heavy lift helicopters. 

In April 1970, the squadron helped break the siege of Dak Seang Special Forces Camp.  North Vietnamese forces had surrounded the camp, and learning from the success of air resupply during their 1969 attack on the Ben Het Camp, also established anti-aircraft artillery positions along likely air resupply corridors.  On the first day of the siege, two C-7s were diverted from their scheduled missions and staged out of Pleiku to make the first airdrops to the camp.  Resupply of the camp was so urgent that all drop-qualified crews of the 483rd Tactical Airlift Wing were ordered to Pleiku to support the operation and eleven sorties were flown that day with cover from Douglas A-1 Skyraiders.  Crews approached the camp from the north or south to use terrain to mask their approaches from enemy flak.  Loss of the third Caribou in five days, including one from the 457th, prompted a move to resupply the camp with night drops, with cover and illumination provided by Fairchild AC-119 Stinger gunships. All 483rd Wing squadrons participated in the operation.  It earned a second Presidential Unit Citation for this action, evacuation of over 2000 refugees from Cambodia, and transportation of the Presidential Southeast Asia Investigation Team to various remote locations in South Vietnam.

The squadron was the last C-7 unit of the 483d Wing to inactivate, ending operations on 25 March 1972 and transferring most of its equipment to the Republic of Viet Nam Air Force at the end of April 1972 as Cam Ranh Bay prepared for closure with the withdrawal of the United States military from Viet Nam.  Seven aircraft, along with aircrew and maintenance personnel, were transferred to the 310th Tactical Airlift Squadron at Tan Son Nhut Airport.

Executive airlift
The second predecessor of the squadron was activated at Andrews Air Force Base, Maryland on 1 April 1975 as the 1402nd Military Airlift Squadron and assigned to the  89th Military Airlift Wing.  The 1402nd was one of the squadrons formed when the Air Force decided to consolidate its administrative airlift fleet under Military Airlift Command.  The Air Force also decided the fleet would become all jet, using North American T-39 Sabreliners, although the squadron continued to operate propeller driven Convair VC-131s for another two years.    In addition, the T-39s provided newly-graduated Air Force pilots with operational experience before assignment to combat units.

In 1984, the squadron ended its pilot readiness training program and replaced its CT-39s with  Learjet C-21s and once again flew the C-12.  It supported intratheater airlift in Southwest Asia from August 1990 through April 1991.  In 1993, its mission shifted from providing administrative airlift to airlift support for high-ranking dignitaries of the US and foreign governments from, flying only Learjets from 1994.  The squadron also supported United States Northern Command during exercises.  The squadron was inactivated in a ceremony held on 14 June 2019.
