The Indian Air Force will retire its last MiG-21 Bison squadrons in September 2025, culminating in a ceremonial farewell widely reported for September 26 at Chandigarh after final operational sorties at Nal, Bikaner in mid-August, marking the end of nearly six decades since the type’s induction in 1963 and its role across conflicts from 1965 to 1971 and beyond. Air Chief Marshal A.P. Singh underscored the transition by flying a tribute sortie in August 2025, reflecting the aircraft’s storied service and the emotional resonance it holds for generations of IAF pilots, including units such as No. 23 “Panthers” and the legacy of squadrons like No. 28 “First Supersonics” and No. 51. The phase-out clears the path for modernization as the IAF replaces the MiG-21 with the indigenous Tejas Mk-1A and complements capabilities with Rafale, amid concerns over squadron strength and induction timelines; reports note two remaining Bison squadrons at Nal will shift to Tejas Mk-1A as deliveries ramp up under existing orders. Commemorative tail art and planned ceremonies will honor veteran aircrew and ground staff while symbolizing the force’s move to more advanced, networked platforms.
