Lockheed F-94B Starfire at the NASA Lewis Research Center

The Air Force contracted Lockheed in November 1948 to create the new F-94s fighters. The first test flight occurred only months later in April 1949. This quick turnaround was due to the fact that the F-94 was based largely on the TF-80 fighter and constructed with parts from the P-80, including its two General Electric I-40 turbojet engines. The F-94Bs entered the Korean War in late 1951, but were initially prevented from flying over enemy territory due to fear that their fire control system would be copied by the enemy if an F-94B went down. The Starfire went on to perform scores of missions escorting B-29 and B-26 bombers deep into enemy territory and acting as interceptors against enemy fighters. In mid-1954 the F-94s were retired from active military service. Lewis acquired the F-94B Starfire in April 1956. At the time, the aircraft industry was preparing for the first use of jet engines for commercial aviation. The amount of noise generated by the engines was a major obstacle. Lewis undertook an extensive program to understand the causes of the noise and develop methods for reducing it. This program included the study of aerodynamic sound at high speed and altitude using the F-94B.
