# 740th Missile Squadron

The 740th Missile Squadron is a United States Air Force unit stationed at Minot Air Force Base, North Dakota. The squadron is equipped with the LGM-30G Minuteman III intercontinental ballistic missile, with a mission of nuclear deterrence.
The squadron was first activated as the 740th Bombardment Squadron in June 1943. After training in the United States with the Consolidated B-24 Liberator, the 740th deployed to the Mediterranean Theater of Operations, participating in the strategic bombing campaign against Germany. It earned two Distinguished Unit Citations for its combat operations. Following V-E Day, the squadron remained in Italy without its flight echelon until inactivating in September 1945.
The squadron was activated in the reserve in 1947, but apparently was not fully manned or equipped before inactivating in June 1949 and transferring its resources to another unit. It was redesignated the 740th Fighter-Day Squadron and activated, but did not become operational before inactivating in July 1957. In November 1962 it was organized as the 740th Strategic Missile Squadron, an LGM-30B Minuteman I squadron. In 1971 it upgraded to the Minuteman III, and is currently a part of the 91st Operations Group.

## Mission

The 740th Missile Squadron controls and maintains 50 launch facilities and 5 missile alert facilities. The squadron is divided into missile operations flights, which are responsible for day-to-day operations, maintenance, and security, and an operations support flight, which is responsible for ensuring the readiness of the missile alert facilities.

## History
### World War II
#### Training in the United States

The squadron was first activated at Alamogordo Army Air Field, New Mexico on 1 June 1943 as the 740th Bombardment Squadron, one of the four squadrons of the 455th Bombardment Group. The initial cadre for the squadron was drawn from the 302d Bombardment Group. In July, a group cadre was given advanced tactical training by the Army Air Forces School of Applied Tactics at Orlando Army Air Base and Pinecastle Army Air Field, Florida. After organizing at Alamogordo, the squadron moved to Utah, where the ground echelon was stationed at Kearns Army Air Base, although flying operations were based at Salt Lake City Army Air Base. After completing training at Langley Field, Virginia, the squadron departed the United States for the Mediterranean Theater of Operations in December 1943. The air echelon began staging through Mitchel Field, New York to ferry their Liberators via the southern ferry route. The ground echelon sailed on the SS Charles Brantley Aycock.

#### Combat operations

The air echelon of the squadron was delayed in Tunisia and was not entirely lodged at the squadron's combat station of San Giovanni Airfield, Italy until 1 February 1944, and the squadron flew its first mission that month. The squadron was engaged primarily in the strategic bombing campaign against Germany, attacking targets like airfields, factories, oil refineries, harbors, marshalling yards in Italy, France, Germany, Austria, Hungary, Romania, and Yugoslavia.
On 2 April 1944, the squadron attacked a ball bearing plant at Steyr, Austria for which it earned a Distinguished Unit Citation (DUC). The primary target, the Daimler-Pusch aircraft engine factory was obscured by clouds, so the unit attacked the nearby ball bearing plant although attacks by an estimated 75 twin engine fighters continued through the bomb run and heavy, accurate flak was encountered. The squadron claimed the destruction of seven of these fighters against the loss of one squadron Liberator.
On 26 June 1944, the squadron encountered fighter opposition that was described as the strongest Fifteenth Air Force had encountered to date, and which destroyed several Liberators of the 455th Group, which was leading the 304th Bombardment Wing on the raid. One squadron Liberator was lost on the raid, while the squadron claimed eleven enemy aircraft destroyed (two shared claims). The squadron pressed its attack on the oil refinery at Moosbierbaum, Austria, for which it received a second DUC.
The squadron provided air support to ground forces in Operation Shingle, the landings at Anzio and the Battle of Monte Cassino in the spring of 1944. It knocked out coastal defenses to clear the way for Operation Dragoon, the invasion of southern France in September. As Axis forces were withdrawing from the Balkan peninsula in the fall of 1944, the squadron bombed marshalling yards, troop concentrations and airfields to slow their retreat. It flew air interdiction missions to support Operation Grapeshot, the Spring 1945 offensive in Northern Italy.
The squadron flew its last combat mission on 25 April 1945 against rail yards at Linz, Austria. Following the surrender of German forces in Italy, it flew some supply missions and transported personnel to ports and airfields for shipment back to the United States. Most of the air echelon returned to the United States, ferrying their aircraft in June. The squadron's remaining ground personnel remained in Italy, moving to Bari Airfield in July 1945, where they serviced the aircraft assigned to headquarters, Fifteenth Air Force. It was inactivated there on 9 September 1945.

### Air Force reserve

The squadron was reactivated as a reserve unit under Air Defense Command (ADC) at Hensley Field, Texas in January 1947, where its training was supervised by ADC's 4122d AAF Base Unit (later the 2596th Air Force Reserve Training Center). It was assigned directly to Tenth Air Force until March, when its parent 455th Group was activated. It was nominally a very heavy bomber unit, but the squadron does not appear to have been fully manned or equipped with operational aircraft while a reserve unit. In 1948 Continental Air Command (ConAC) assumed responsibility for managing reserve and Air National Guard units from ADC. President Truman’s reduced 1949 defense budget required reductions in the number of units in the Air Force. ConAC also reorganized its reserve units under the wing base organization system in June 1949. As a result, the squadron was inactivated and its personnel and equipment were transferred to elements of the 443d Troop Carrier Wing, which was activated simultaneously.

### Tactical Air Command

The squadron was redesignated the 740th Fighter-Day Squadron and activated at Myrtle Beach Air Force Base, South Carolina in July 1956 as Tactical Air Command planned to organize a second North American F-100 Super Sabre wing there. Some personnel were assigned to the unit, but it never became operational with aircraft. It was inactivated in July 1957 and its few personnel assigned were reassigned to elements of the 354th Fighter-Day Wing.

### Intercontinental ballistic missile squadron

The squadron was redesignated the 740th Strategic Missile Squadron and activated on 1 November 1962 as an intercontinental ballistic missile squadron at Minot Air Force Base, North Dakota. The squadron was initially equipped with 50 LGM-30B Minuteman Is, and placed its first missile on alert in 1963. The 740th upgraded to LGM-30G Minuteman III between December 1970 through December 1971 and has maintained ICBMs on alert ever since.
The squadron has undergone several changes in assignment that did not affect its mission. In June 1968, the 455th Strategic Missile Wing at Minot was replaced by the 91st Strategic Missile Wing, which moved from Glasgow Air Force Base, Montana to Minot on paper, and the squadron was reassigned to the 91st Wing. In September 1991 Strategic Air Command (SAC) reorganized its missile wings under the combat wing organization, and the 91st Wing's missile squadrons were assigned to the reactivated 91st Operations Group and dropped the "strategic" from their name. In 1992, the Air Force reorganized its combat forces. SAC was inactivated and the squadron became an element of Air Combat Command until July 1993, when it became part of Air Force Space Command. Between 1994 and 1996, the wing was reduced to group level. In December 2009, the Air Force's nuclear capable missile units, including the 740th were transferred to Air Force Global Strike Command.
Squadron missile sites are designated by flight, using one letter of the alphabet, followed by a number. The first site in each flight is #1 and designates the Missile Alert Facility, which consists of an above-ground structure plus an underground Launch Control Center staffed by two officers. The Launch Facilities, are numbered 2 through 11 and are connected to the Launch Control Center by hardened intersite cables, which also interconnect flights. The 740th includes flights A through E.
