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.



Established in 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 WPS 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.

World War II

Formed as a P-40 Warhawk pursuit squadron in January 1941 as part of the Army Air Corps Northeast Defense Sector (later I Fighter Command) at Mitchel Field, New York. Trained in New England and provided air defense of the northeast after the Japanese attack on Pearl Harbor.

Took part in the British Western Desert Campaign, engaged in combat during the Battle of El Alamein and, as part of Ninth Air Force, supported the Commonwealth Eighth Army's drive across Egypt and Libya, escorting bombers and flying strafing and dive-bombing missions against airfields, communications, and troop concentrations until Axis defeat in Tunisia in May 1943. 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.

Participated in the French campaign against Elba in June 1944 and in the invasion of Southern France in August. It engaged in interdiction and support operations in northern Italy from September 1944 to May 1945.

The 66th flew its last combat mission on 2 May 1945. Remained in northern Italy after the end of the European War, demobilizing throughout the summer of 1945. It was reassigned to the United States in August 1945 without personnel or equipment and was inactivated at the end of August.

Reactivated in August 1946 as part of Eleventh Air Force (Later Alaskan Air Command) as part of the air defense forces in the northwest Pacific.

Later, it was equipped with F-80Bs in March–April 1948, F-80Cs in October–December 1948, F-94Bs in the summer of 1951, and F-89Cs in September 1953. With these aircraft, the squadron provided fighter aircraft defense in support of the Alaska Area until late in the 1950s.
