IX Fighter Command

The IX Fighter Command was a United States Army Air Forces formation. Its last assignment was with the Ninth Air Force, based at Erlangen, Germany. It was inactivated on 16 November 1945.

IX Fighter Command was the primary tactical fighter air arm of Ninth Air Force in the Western Desert Campaign in North Africa during 1942-1943. Reassigned to England, it became the dominant tactical air force over the skies of Western Europe during the 1944 Battle of Normandy and the Western Allied invasion of Germany in 1945.

After its inactivation, the majority of its (along with Twelfth Air Force) units were incorporated into the postwar United States Air Force Tactical Air Command.

North Africa
Entered combat in Egypt during January 1943 as command and control organization for Ninth Air Force fighter units assigned to Western Desert Campaign in Libya and Tunisia. Although subordinate wings assigned to command, combat groups attached to Royal Air Force Western Desert Air Force.

Command reassigned to England in November 1943 as tactical fighter component for Ninth Air Force as part of Normandy invasion planning. Assigned units reassigned to Twelfth Air Force

Western Europe
During the winter of 1943/44 IX Fighter Command expanded at an extraordinary rate so that by the end of May 1944, its complement ran to 45 flying groups operating some 5,000 aircraft. Initial missions from England consisted of fighter sweeps over troop concentrations and attacks on enemy positions and airfields, primarily on German Fifteenth Army units in the Pas-de-Calais region of France as well as around Normandy and Cotentin Peninsula. On D-Day IX Fighter Command units carried out massive air attacks on German forces in Normandy area with P-51 Mustang and P-47 Thunderbolt fighter-bombers. Air cover during the morning amphibious assault by Allied forces on the beaches of France was flown by P-38 Lightnings.

With the beaches secure, grups began deploying to France on June 16, 1944, ten days after the Normandy invasion by moving P-47 Thunderbolts to a beach-head landing strip. During the Battle of Normandy, its tactical air units then provided the air power for the Allied break-out from the Normandy beachhead in the summer of 1944 during the Battle of Cherbourg, Caen, and the ultimate breakout from the beachhead, Operation Cobra.

By early August most IX Fighter Command groups were transferred to bases in France and assigned to the U. S. Twelfth Army Group. Command then reorganized, with units transferred to three Tactical Air Commands and which directly supported Army ground units, along with an air defense command to defend Allied-controlled areas.
