How many Mig 21s had Vietnam got?

NORTH Vietnam, during the war, never exceeded approximately 200 MiGs at any one given time. When they were lost (shot down) they were replaced, on a one for one basis; unless a new squadron was being formed. The majority of MiGs in the NVAF were MiG17s, followed by Mig21s, with the lowest amount being the MiG19s (mostly the J6 versions supplied by Red China). A fair estimate of NVAF MiG21s during the war might be between 60 and 80 jets. NVAF MiG17/MiG21 drivers were trained in the USSR, while MiG19 (J6) NVAF pilots were trained in Red China.
