Mikoyan-Gurevich MiG-21F-13 "Fishbed-C"

The MiG-21F-13 (izdeliye 74, NATO "Fishbed-C") was the first MiG-21 model produced in large numbers. Compared with the short-lived MiG-21F it dropped one of the two 30 mm cannon in favour of two K-13 (R-3S) infrared-homing missiles on underwing pylons. It had only an SRD-5ND ranging radar, so it was a clear-weather day fighter dependent on ground control. Soviet factories in Gorky and Moscow built 513 between 1960 and 1965.

Czechoslovakia's Aero Vodochody built 194 more under licence as the S-106 between 1962 and 1972, recognisable by a solid fairing behind the canopy. Yugoslavia's first MiG-21s were 45 F-13s, delivered from 25 December 1962 under the local designation L-12, and the type also went to the Warsaw Pact air forces and to Egypt.

The F-13 was also the basis of China's J-7. In the United States, the Air Force secretly flew a small fleet of ex-foreign "Fishbed-C" aircraft for dissimilar air combat training with the 4477th Test and Evaluation Squadron at Tonopah, Nevada.
