9th Air Force patch

9th Air Force patch, original, WW2.

North Africa

In Egypt during January 1943, IX Fighter Command became the control organization for Ninth Air Force fighter units assigned to the Western Desert Campaign (Libya and Tunisia).

Although wings were officially subordinate to the command, combat groups were attached to the Desert Air Force, which included squadrons of the Royal Air Force, Royal Australian Air Force and South African Air Force.

IX Fighter Command was reassigned to England in November 1943 as part of Normandy invasion planning. Its subordinate units were reassigned to the 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, groups 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.

XXIX Tactical Air Command supported the Ninth United States Army in the north

IX Tactical Air Command supported the United States First Army in the center

XIX Tactical Air Command supported the United States Third Army in the south

IX Air Defense Command provided air defense of Allied-controlled Western Europe

After units reassigned, remained as command organization until after VE-Day when performed occupation duty in Germany.
