USAAF 339th Fighter Squadron was a United States Army Air Forces unit activated during World War II as part of the 348th Fighter Group. It served in the European Theater of Operations (World War II) and the Mediterranean Theater of World War II providing fighter escort, air superiority, and ground-attack missions. The squadron participated in major operations across North Africa, the Sicily Campaign, and the Italian Campaign before inactivation after the war.

History

The squadron's lineage traces to activation in 1942 under the auspices of the United States Army Air Forces expansion following Pearl Harbor attack. Initially assigned to the III Fighter Command, it trained stateside before deploying to the Mediterranean Theater of Operations to support Operation Torch landings in French North Africa. During its tenure the unit operated in coordination with forces involved in the Tunisia Campaign, the Sicily Campaign (Operation Husky), and the advance up the Italian peninsula, interfacing with air components from the Twelfth Air Force, Ninth Air Force, and Allied air commands.

Formation and Training

Formed amid the rapid buildup ordered by the War Department (United States) in 1942, the squadron assembled cadre from personnel drawn from Army Air Forces Training Command fields. Initial training took place at continental US airfields within III Fighter Command jurisdiction, where pilots and ground crews trained on single-engine fighters and tactics influenced by lessons from the Battle of Britain and early North African Campaign engagements. The unit engaged in combined-arms exercises with the United States Army Ground Forces and coordinated mission planning with elements of the Royal Air Force and Free French Air Force prior to overseas shipment.

World War II Operations

Deployed to the Mediterranean Theater of Operations in late 1942, the squadron undertook escort sorties for B-17 Flying Fortress and B-24 Liberator formations, interdiction missions against Axis supply lines, and air superiority sweeps during Operation Torch and the subsequent Tunisia Campaign. In support of Operation Husky, the unit conducted strafing and close air support missions for amphibious assaults in Sicily (1943), cooperating with U.S. Fifth Army ground forces. During the Italian Campaign the squadron flew interdiction missions against bridges and convoys near Naples, supported coastal operations at Salerno, and engaged Luftwaffe fighters over the Anzio beachhead, aligning sortie planning with headquarters of the Twelfth Air Force and liaison officers attached to Allied Force Headquarters.

Aircraft and Equipment

Throughout its combat service the squadron operated variants of the single-engine fighter widely used by United States Army Air Forces, including the Curtiss P-40 Warhawk early in the North African operations and transitioning to the Republic P-47 Thunderbolt for high-altitude escort and ground-attack roles. Armament suites typically comprised .50 caliber machine guns, rockets, and external bomb loads adapted for interdiction tasks; maintenance procedures adhered to standards promulgated by Air Service Command logistics directives. The unit also made use of field-modified equipment and captured Axis materiel scavenged during forward operations in coordination with Army Ordnance Department detachments.

Command Structure and Personnel

Operational command fell under the 348th Fighter Group and higher echelon control by the Twelfth Air Force in theater. Squadron leadership rotated among commissioned officers drawn from United States Army Air Forces Officer Candidate School graduates and experienced non-commissioned pilots transferred from other combat units. Ground echelon staffing incorporated specialists trained under Air Corps Technical School curricula, including armament technicians, flight engineers, and radio operators, while intelligence duties coordinated with Mediterranean Allied Air Forces and signals elements of the British Intelligence Corps.

Honors and Campaigns

The squadron earned campaign credits for participation in Algeria-French Morocco, Tunisian-Operation, Sicily, Naples-Foggia, Anzio, and other Mediterranean and European campaigns recognized by the Army of the United States theater award system. Individual aircrew received decorations drawn from Distinguished Flying Cross (United States), Air Medal, and theater commendations for sorties supporting pivotal operations linked to the Allied invasion of Italy and interdiction of Axis logistics networks. The group's operational record was archived within Air Force Historical Research Agency collections alongside after-action reports filed by unit adjutants.

Legacy and Postwar Disposition

Following Victory in Europe Day and demobilization directives issued by the Army Service Forces, the squadron returned to the United States and was inactivated in 1946 amid widespread postwar force reductions directed by the War Department. Legacy elements were absorbed into postwar reserve and active component reorganizations that contributed personnel and traditions to later United States Air Force fighter units. Historical documentation and unit honors are preserved in archives maintained by the National Archives and Records Administration and curated displays at museums associated with the National Museum of the United States Air Force and regional aviation heritage organizations.
