List of Mikoyan-Gurevich MiG-21 variants

All subsequent development of the J-7 was indigenous to China and different from Soviet-made versions.

The sole locally built version of the MiG-21F-13 differed externally from the Soviet-built examples by the solid dural sheet fairing behind the cockpit canopy, as opposed to the transparent one on the original Soviet MiGs.

The production of the MiG-21 in India under license by Hindustan Aeronautics in Nasik started with the MiG-21FL in 1966 in four phases starting with the assembly of CKD kits, moving on to subassemblies, parts, and finally advancing to production from scratch.

205 MiG-21FLs, designated Type 77 and nicknamed Trishul ("Trident"), were built in India between 1966 and 1972; the first one built entirely from Indian-made components was delivered to the IAF on 19 October 1970, with the first Indian-made R11F2S-300 powerplant leaving the assembly line on 2 January 1969.
