When it comes to supersonic jets, no aircraft has matched the legacy of the MiG-21. First flown in 1955, it went on to become the most produced supersonic fighter in history, with more than 11,000 built. Designed by the Soviet Union for speed, agility, and mass production, the MiG-21 armed over 50 nations and shaped the course of Cold War air combat.
Nicknamed “Fishbed” by NATO, the MiG-21 could reach Mach 2 and offered supersonic power at a fraction of the cost of its Western rivals. It gave smaller nations serious airpower, spreading Soviet influence across Asia, Africa, the Middle East, and beyond.
The jet saw action across decades of conflicts, from dogfights with American F-4 Phantoms in Vietnam to battles over the Middle East and South Asia. In India, MiG-21s played decisive roles in the 1965 and 1971 wars with Pakistan. Remarkably, as late as 2019, an upgraded MiG-21 Bison of the Indian Air Force downed a Pakistani F-16, proving its bite even in the modern era.
At its peak, the MiG-21 flew with more than 60 air forces. China also built its own version, the Chengdu J-7, which was exported widely. For many countries, the MiG-21 was their first supersonic jet, affordable, rugged, and transformative.
But its brilliance came with trade-offs. Short range, modest payload, and high landing speeds made it demanding to fly. In India, frequent crashes earned it the grim nickname “flying coffin.” Yet continual upgrades kept it relevant for decades.
With the retirement of India’s last MiG-21 squadron, the curtain has finally closed on an era. India now turns to advanced fighters like the HAL Tejas and French Rafale. Still, the MiG-21’s record is unmatched. No other supersonic aircraft has flown so widely, been built in such numbers, or left such a mark on air combat history.
