Training and strategic bombing The squadron was first organized in October 1943 at
Alamogordo Army Air Field, New Mexico, as one of the original squadrons of the
492d Bombardment Group. Its
cadre was drawn from the
859th Bombardment Squadron, a former
antisubmarine unit whose mission had transferred to the
Navy. By January 1944, most of the ground echelon of the squadron had been used to form other bomber units.
2d Bombardment Division, which controlled
VIII Bomber Command's Liberator units in England, began to form a new ground echelon for the squadron from personnel of bomber units already in England, while the air echelon of the 856th continued training with
Consolidated B-24 Liberators at Alamogordo. The air echelon began to depart Alamogordo on 1 April 1944, following the southern ferry route, while the few remaining members of the ground echelon departed on 11 April, sailing on the on 20 April. When the 492d Group returned to strategic operation, on 20 June
Luftwaffe fighters, primarily
Messerschmitt Bf 110s, using
air to air rockets shot down fourteen of the 492d Group's B-24s. Heavy losses, this time to fighters from
Jagdgeschwader 3, were again suffered on 29 June. On 5 August, the decision was made to withdraw the 492d Group from combat. With the 492d Group, the squadron flew 198
Operation Carpetbagger missions by the middle of September. With black-painted aircraft configured with engine flame dampeners and optimized for night operations, the group operated chiefly over France with B-24s and
Douglas C-47 Skytrains, transporting agents, supplies, and propaganda leaflets to Resistance fighters. As
Allied forces moved forward through northern France and into Belgium, the need for Carpetbagger missions decreased and operations ended on 16 September 1944. The squadron's support for the
French Resistance earned it the
French Croix de Guerre with Palm. With the drawdown of the Carpetbagger mission, the squadron concentrated on hauling gasoline to advancing
mechanized forces in France and Belgium. After December 1944, the squadron began limited night bombing operations. The squadron left England for the United States in early August 1945. In August 1945 it began to reform at
Kirtland Field, New Mexico as a
Boeing B-29 Superfortress very heavy bomber squadron, however it became unnecessary when the Pacific War ended and it was inactivated on 17 October 1945. ==Lineage==
