The 106th was transferred from Tactical Air Command to Air Defense Command (ADC) and assumed an air defense mission over Long Island and New York City, entering the Jet Age with the limited all-weather F-94B Starfire interceptor. With the Starfire, the 102d began standing end of runway air defense alert, ready to launch interceptors if ADC Ground Intercept Radar picked up an unidentified target. The squadron stood air defense alert from one hour before sunrise until one hour after sunset every day, 365 days a year. In 1957, ADC upgraded the 102d Fighter-Interceptor Squadron to the all-weather F-86D Sabre Interceptor. With the receipt of the F-86D, the alert mission was extended to 24 hours a day/7 days a week/365 days a year.
