"Altogether, the tactical air forces had 2,434 fighters and fighter-bombers, together with approximately 700 light and medium bombers available for the Normandy campaign. This force first struck against the Germans during the preparatory campaign prior to D-Day. At D minus 60 days, Allied air forces began their interdiction attacks against rail centers; these attacks increased in ferocity and tempo up to the eve of the invasion itself and were accompanied by strategic bomber raids against the same targets. The bridge campaign, which aimed at isolating the battlefield by cutting Seine bridges below Paris and Loire bridges below Orléans, began on D minus 46. Here, fighter-bombers proved more efficient than medium or heavy bombers, largely because their agility enabled them to make pinpoint attacks in a way that the larger bombers, committed to horizontal bombing runs, could not. The fighter-bombers also had the speed, firepower, and maneuverability to evade or even dominate the Luftwaffe. Though ground fire and (rarely) fighters did claim some attacking fighter-bombers, the loss rate was considerably less than it would have been with conventional attack or dive bombers. By D minus 21, Allied air forces were attacking German airfields within a radius of 130 miles of the battle area and these operations too continued up to the assault on the beachhead." Air Support on the Beaches "During the June 6 D-Day assault itself, a total of 171 squadrons of British and AAF fighters undertook a variety of tasks in support of the invasion. Fifteen squadrons provided shipping cover, fifty-four provided beach cover, thirty-three undertook bomber escort and offensive fighter sweeps, thirty-three struck at targets inland from the landing area, and thirty-six provided direct air support to invading forces. The Luftwaffe's appearance was so minuscule that Allied counterair measures against the few German aircraft that did appear are not worth mentioning. Of far greater importance was the role of aircraft in supporting the land battle. As troops came ashore at Normandy, they made an unpleasant discovery all too familiar to the Marine Corps and Army operating in the Pacific campaign. Despite the intensive air and naval bombardment of coastal defenses, those defenses were, by and large, intact when the invasion force "hit the beach." This was particularly true at OMAHA beach, where American forces suffered serious casualties and critical delays. Despite a massive series of attacks by Eighth Air Force B-17s, B-24s and medium bombers in the early hours of June 6, the invading troops were hung up on the beach. The air commanders themselves had, in fact, predicted that the air and naval bombardments would not achieve the desired degree of destruction of German defensive positions. The Army's general optimism that air would cleanse the beaches before its approach, however, was shattered. Only the subsequent success of fighter-bombers operating against the battlefield would revive the Army's confidence in air support. Indeed, throughout the post-Normandy campaign--and in the Second World War as a whole--the fighter-bomber proved overwhelmingly more valuable in supporting and attacking ground forces in the battle area than did the heavy or even the medium bomber."
