MiG-21MF (1970; Izdeliye 96F; NATO "Fishbed-J")
M = Modernizirovannyy ("Modernised")
F = Forsirovannyy ("Uprated [engine]")
Export version of the MiG-21SM, with RP-22 radar and R13-300 turbojet. The choice of weapons loads was increased with the addition of the R-60 (NATO: AA-8 "Aphid") and later the R-60M IR-seeking AAM. These were also licence-built in India by HAL as the Type 88.
