 In December 1957, the 83d FIS received AIM-9 Sidewinder-armed Lockheed F-l04A Starfighters and become the first operational F-104 squadron in ADC.In addition, the squadron received the two-seat, dual-control combat trainer F-104B.The performance of the F-104B was almost identical to that of the F-104A, but the lower internal fuel capacity reduced its effective range considerably.
