The 4756th Air Defense Wing was the designation of two different discontinued United States Air Force organizations. Both wings were stationed at Tyndall Air Force Base (AFB), Florida and fulfilled similar missions. The first was organized in 1957 when Air Defense Command (ADC) assumed responsibility for Tyndall from Air Training Command and focused on weapons testing and development and evaluating the readiness of ADC fighter units. The wing also controlled a ground control intercept radar squadron. This wing was discontinued in 1960 and its mission transferred to its parent 73d Air Division.
