The United States Air Force's 66th Weapons Squadron is a United States Air Force Weapons School Fairchild Republic A-10 Thunderbolt II instructional flying unit, at Nellis Air Force Base, Nevada.

The squadron was first activated in the build up of the American military prior to its entry into World War II as the 66th Pursuit Squadron. After training in the United States, it deployed to North Africa in 1942, and participated in combat in the Mediterranean Theater of Operations. The squadron moved forward through Egypt, Libya, and Tunisia with Allied forces, moving to Italy in 1943. The 66th earned three Distinguished Unit Citations for its combat actions before returning to the United States for inactivation in 1945.

The following year, the squadron was activated for the air defense of Alaska. It served in this role, and briefly in the air defense of California, before inactivating in 1958. It was reactivated in 1969 as the 66th Fighter Weapons Squadron, an advanced training unit for Wild Weasel tactics until inactivating in 1981.


Active since 2003, the 66th Weapons Squadron teaches graduate-level instructor courses that provide training in weapons and tactics employment to officers of the combat air forces and mobility air forces. The 66th focuses on the A-10 Thunderbolt II, with the climax of the course being the mission employment phase, a two-week staged battle over the Nevada Test and Training Range.

Upon graduation, the new weapons officers return to the field to serve as unit weapons and tactics officers, providing advanced instruction and technical advice to their commanders, operations officers, and personnel.

The unit participated in the reduction of Pantelleria (May–June 1943) and the conquest of Sicily (July–August 1943).

The squadron supported the British Eighth Army's landing at Termoli and subsequent operations in Italy, being reassigned to Twelfth Air Force in August 1943. It flew dive-bombing, strafing, patrol, and escort missions.

In 1944, converted to P-47 Thunderbolt aircraft and flew interdiction operations in Italy. They moved to Corsica on 30 March 1944 to operate as a separate task force. It flew interdiction missions against railroads, communication targets, and motor vehicles behind enemy lines, providing a minimum of 48 fighter-bomber sorties per day.
