533d Training Squadron

The squadron was first activated on 3 November 1942 at Gowen Field, Idaho as the 533d Bombardment Squadron, one of the four original squadrons of the 381st Bombardment Group. It gathered its initial cadre at Gowen, but only began training for combat with the Boeing B-17 Flying Fortress afer moving to Pyote Army Air Field, Texas at the end of the year. On 8 May 1943, the ground echelon began moving to the Port of Embarkation at Camp Kilmer, New Jersey, and boarded the RMS Queen Elizabeth for the European Theater of Operations on 27 May. The air echelon marshalled at Salinas Army Air Field, Kansas and began movement by the North Atlantic Ferry Route on 15 May.[2][4][5]

The air echelon of the squadron arrived at RAF Bovingdon in late May 1943. The following month, the squadron was reunited at RAF Ridgewell, which was to be its combat station for the rest of the war. The squadron entered the strategic bombing campaign against Germany, when it flew its first mission on 21 June, a diversionary attack against Antwerp.[5][6] Its targets in France included an aircraft assembly plant near Villacoublay, and an engine plant at Le Mans , locks at Saint-Nazaire, and Amiens – Glisy Aerodrome. It also attacked an aircraft plant in Brussels, Belgium. During Blitz Week, it bombed nitrate factories in Heroya, Norway, stopping production for over three months.[4][7]

The squadron also flew deeper penetration missions into Germany. It hit oil refineries at Gelsenkirchen, submarine pens at Kiel, aircraft plants at Kassel and Leipzig, industrial targets in Münster, marshalling yards at Offenberg, and the ball bearing plants at Schweinfurt. On 8 October 1943, despite heavy enemy interceptor opposition, it accurately struck shipyards at Bremen, for which it was awarded the Distinguished Unit Citation (DUC).[4] All squadron bombers that returned from this mission[note 2] received battle damage.[8] It received a second DUC for attacks on aircraft plants in Germany on 11 January 1944. In late February 1944, the unit participated in Big Week, the intensive attacks on the German aircraft industry.[4]

The squadron was occasionally taken off strategic operations to perform air support and interdiction missions. It bombed bridges and airfields near the beachhead to support Operation Overlord, the invasion of Normandy, in June 1944. The following month, it attacked positions of enemy forces opposing Operation Cobra, the breakout at Saint Lo. It supported Operation Market Garden, the airborne attacks in the Netherlands near Arnhem, in the fall. From December 1944, through January 1945, it attacked lines of communications and airfields near the battle zone during the Battle of the Bulge. It also supported the Allied crossing of the Rhine and push through central Germany in March 1945.[4]

The squadron flew its last mission on 26 April 1945 and the majority of the unit's aircraft departed the theater on 24 May 1945. Ground personnel sailed on the RMS Queen Elizabeth on 24 June, arriving in the US by the end of the month. The squadron was located at Sioux Falls Army Air Field, South Dakota a few days later and was inactivated on 24 August 1945.[2][5][4]

The unit was redesigned the 533d Strategic Missile Squadron and organized at McConnell Air Force Base, Kansas on 1 August 1962 as a part of the 381st Strategic Missile Wing. The squadron began training in preparation for LGM-25C Titan II, and the 381st Wing put its first Titans on alert in July 1963.[9] It operated nine Titan II underground silos constructed beginning in 1960; the first site going operationally ready in October 1963 The nine missiles remained on alert for over 20 years during the Cold War. On 24 August 1978, an accident at Site 533-7 involving an oxidizer leak killed two Air Force personnel, and caused the temporary evacuation of local communities. The damage to the site was determined to be unrepairable and the silo was permanently closed.

The squadron operated the following missile sites:

LGM-25C Titan II Sites

In October 1981, President Ronald Reagan announced that as part of the strategic modernization program, Titan II systems were to be retired by 1 October 1987. Inactivation of the sites began in September 1984, In November 1985, the squadron was inactivated and its remaining active missiles were transferred to the 532d Strategic Missile Squadron.[10]

After removal from service, the silos had reusable equipment removed by Air Force personnel, and contractors retrieved salvageable metals before destroying the silos with explosives and filling them in. Access to the vacated control centers was blocked off. Missile sites were later sold off to private ownership after demilitarization. Today the remains of the sites are still visible in aerial imagery, in various states of use or abandonment.

Redesignated and activated on 30 September 1994 as the 533d Training Squadron, Air Education and Training Command the 533d provides initial qualification training for attack warning, space surveillance, and counterdrug missions. Until 2003, The 534th Training Squadron trained crews in satellite command and control. That year, the 534th inactivated and the 533d and its training responsibilities.[10]
