548th Strategic Missile Squadron

The 548th Strategic Missile Squadron is an inactive United States Air Force unit. It was last assigned to the 40th Strategic Aerospace Wing at Forbes Air Force Base, Kansas, where it was inactivated on 25 March 1965. At Forbes, the 548th was equipped with the SM-65E Atlas intercontinental ballistic missile, with a mission of nuclear deterrence.

The squadron was first activated during World War II in December 1942 as the 548th Bombardment Squadron. After training in the United States, it deployed to England, where it participated in the strategic bombing campaign against Germany. The squadron was twice awarded the Distinguished Unit Citation for its actions during the war. Following V-E Day, the squadron returned to the United States, where it was inactivated. The squadron was activated in the reserve from 1947 to 1949, but does not appear to have been fully manned or equipped.

Initial activation and training
The squadron was first activated at Davis-Monthan Field, Arizona as the 548th Bombardment Squadron, one of the four original squadrons of the 385th Bombardment Group. The following month it moved to El Paso Army Air Field, Texas, but did not receive a full complement of personnel and begin training with Boeing B-17 Flying Fortress until it moved to Geiger Field, Washington in February 1943. It completed its training and began deploying to the European Theater of Operations. The air echelon staged through Kearney Army Air Field, Nebraska in May 1943 and ferried its Flying Fortresses to England via the northern ferry route. The ground echelon left for the port of embarkation and sailed on the RMS Queen Mary on 23 June 1943.

Combat in Europe
The squadron assembled at its combat station, RAF Great Ashfield, England, and began participating in the strategic bombing campaign against Germany, flying its first combat mission on 17 July 1943. The unit carried out attacks on industrial targets, including communications centers as well as air bases in Belgium, France, Germany, the Netherlands, Belgium and Norway, striking targets as far away as Poland. On 17 August 1943, the squadron participated in an attack on the Messerschmitt aircraft factory at Regensburg, which involved a long flight over heavily defended enemy territory with little protection from escorting fighters. For this mission, the squadron received the Distinguished Unit Citation. On 12 May 1944, the squadron flew with the 385th Group as it led the 4th Combat Bombardment Wing through heavy opposition to attack an airplane repair facility at Zwickau. An estimated 200 enemy fighters attacked the bomber stream, heavily disordering its formation. The bombers were able to reform and achieved a high degree of accuracy with their bombs. For this attack, the 548th received a second DUC.

Strategic industrial targets for the squadron in Germany included the AGO Flugzeugwerke factory at Oschersleben and the Henschel Flugzeugwerke factory at Marienberg; a battery manufacturing plant at Stuttgart, oil refineries at Ludwigshafen and Merseburg and rail marshalling yards at Munich and Oranienburg. It also attacked Luftwaffe bases at Beauvais/Tille Airfield and Chartres Airfield, France.

The squadron was occasionally diverted from the strategic bombing mission to perform air support and interdiction missions. It struck coastal defenses in June 1944 in preparation for Operation Overlord, the Normandy invasion, and on D-Day attacked transportation chokepoints and marshalling yards. In late July, it attacked enemy positions to support Operation Cobra, the breakout at Saint Lo. In late December 1944 and early January 1945, it carried out attacks on German fortifications and transportation to support forces engaged in the Battle of the Bulge. As the Allies made their final thrust through France into Germany, it attacked troop concentrations and communications targets.

The squadron flew its last mission on 20 April 1945. Following V-E Day, the squadron transported prisoners of war from Germany and flew six missions dropping food supplies in the Netherlands. The air echelon began ferrying its aircraft back to the United States on 19 June and all bombers had departed Great Ashfield by the end of the month. The ground echelon of the squadron left Europe in August 1945, sailing on the RMS Queen Elizabeth and the squadron was inactivated in the United States at Sioux Falls Army Air Field, South Dakota on 28 August 1945.

Air Force reserve
On 15 September 1947, the squadron was activated under Air Defense Command (ADC) in the reserve at Selfridge Field, Michigan. ADC's 136th AAF Base Unit (later the 2242d Air Force Reserve Training Center) supervised the unit's training. In July 1948 Continental Air Command (ConAC) assumed responsibility for managing reserve and Air National Guard units from ADC. The squadron does not appear to have been fully manned or equipped during this period. The 548th was inactivated when ConAC reorganized its reserve units under the wing base organization system in June 1949. President Truman’s reduced 1949 defense budget also required reductions in the number of units in the Air Force,  The squadron's personnel and equipment were transferred to elements of the 439th Troop Carrier Wing.

Intercontinental ballistic missile squadron
The squadron was organized at Forbes Air Force Base, Kansas in July 1960 as the 548th Strategic Missile Squadron, a Strategic Air Command (SAC) SM-65E Atlas intercontinental ballistic missile launch squadron. Nearly 6 months later, on 24 January 1961, the first Atlas missile arrived at Forbes. By October, all nine sites had their Atlas E missiles. On 16 October 1961, Air Force Ballistic Missile Activation Chief, Maj. Gen. Gerrity turned over operational control of the sites to SAC.

The squadron operated nine missile sites:
 * 548–1, 2.5 mi N of Rock Creek, KS    39.27972°N, -95.53056°W
 * 548–2, 1.9 mi SW of Worden, KS    38.7675°N, -95.36806°W
 * 548–3, 4.8 mi WNW of Waverly, KS    38.43056°N, -95.67833°W
 * 548–4, 4.8 mi SSW of Burlingame, KS    38.69472°N, -95.88°W
 * 548–5, 3.9 mi NW of Bushong, KS    38.68639°N, -96.30222°W
 * 548–6, 6.1 mi W of Dover, KS    38.97667°N, -96.04889°W
 * 548–7, 1.8 mi NW of Wamego, KS    39.22278°N, -96.32556°W
 * 548–8, 2.5 mi E of Delia, KS    39.245°N, -95.91944°W
 * 548–9, 4.2 mi N of Holton, KS    39.52583°N, -95.74028°W

During the Cuban Missile Crisis, on 20 October 1962, SAC directed that the squadron's Atlas E missiles that were not on alert for modifications be placed on alert status "as covertly as possible." Training was suspended and missiles being used for operational training were to be placed on alert as soon as liquid oxygen became available. From 3 November the number of alert missiles was reduced until on 29 November the number was the same as before the crisis. As tensions eased, on 15 November normal training resumed.

In August 1964, the squadron's parent 40th Strategic Aerospace Wing became nonoperational and the squadron was reassigned to the 55th Strategic Reconnaissance Wing. This assignment was short-lived, as on 19 November 1964, the Department of Defense announced that all Atlas E and F and Titan I missiles were being removed from the inventory. The first squadron missiles were taken off alert on 4 January 1965. Removal of missiles from alert and shipment to Norton Air Force Base, California at a rate of two per week began in January 1965 and was complete by 12 February 1965. The squadron was inactivated on 25 March 1965 and its missile sites turned over to the base civil engineer for management until transferred to the General Services Administration for disposal.
