FIRST EIGHTH AIR FORCE HEAVY BOMBER RAID OVER EUROPE

First Eighth Air Force heavy bomber raid over Europe

Four days after the creation of that new engineering district, another milestone unfolded in the skies over occupied Europe on August 17th, 1942. That day, B-17 Flying Fortress bombers of the Eighth Air Force launched the first American heavy bomber raid against a target in occupied France, striking railyards and industrial facilities around Rouen. British-based American crews had trained for months to carry out daylight precision bombing, an approach that contrasted with the night area bombing practiced by the Royal Air Force. The raid was limited in scale but deep in symbolic meaning, announcing that United States air power had arrived in the European theater. In the years that followed, formations of American heavy bombers and their escort fighters would launch ever larger raids against German industry and transportation, suffering severe losses while also inflicting significant damage. The August 17th mission at Rouen marked the beginning of that long, costly air campaign that became central to Allied strategy.
