In May 1942, the 99th Pursuit Squadron was renamed the 99th Fighter Squadron. It earned three Distinguished Unit Citations (DUC) during World War II. The DUCs were for operations over Sicily from May 30th - June 11, 1943, Monastery Hill near Cassino from May 12-14, 1944, and for successfully fighting off German jet aircraft on March 24, 1945. The mission was the longest bomber escort mission of the Fifteenth Air Force throughout the war. The 332nd flew missions in Sicily, Anzio, Normandy, the Rhineland, the Po Valley and Rome-Arno and others. Pilots of the 99th once set a record for destroying five enemy aircraft in under four minutes.
