Lockheed F-94 Starfire

The Lockheed F-94 Starfire is a first-generation jet powered all-weather day/night interceptor aircraft designed and produced by Lockheed Corporation. It was the first operational United States Air Force (USAF) fighter equipped with an afterburner as well as being the first jet-powered all-weather fighter to enter combat during the Korean War. The F-94 was developed to fulfil a specification issued by the USAF in 1948, seeking a new interceptor capable of day and night operations to replace its piston-engined types in light of recent military advances made by the Soviet Union. The F-94 was derived from the successful Lockheed T-33 Shooting Star trainer; being a relatively simple conversion from an established aircraft led to USAF officials viewing it as a low risk option and opting to procure the type. Maintaining a high level of parts commonality with the preceding aircraft, the majority of the F-94's external changes were related to the adoption of a larger nose that accommodated multiple guns, radar, and an automatic fire control system. Engine thrust was also bolstered by adding an afterburner to the Allison J33 powerplant used. On 16 April 1949, the prototype YF-94 conducted its maiden flight. While teething problems were encountered, these were overcome relatively quickly. During May 1950, the F-94A reached operational service with Air Defense Command (ADC), its principal operator, where the type soon replaced the piston-engined North American F-82 Twin Mustang in the all-weather interceptor role. It was soon followed by the F-94B, a refined model that proved to have greater engine reliability and a more spacious cockpit; the F-94C equipped with a thinner wing, a more powerful Pratt & Whitney J48 engine, and a new Hughes E-5 fire control system also followed. Further models, including a dedicated aerial reconnaissance variant, were proposed but ultimately not pursued. In the interceptor role,...
