A few weeks ago, the Indian Air Force (IAF) retired the iconic Srinagar-based No. 51 Squadron which operates the MiG-21 Bisons—the same squadron that Group Captain (then Wing Commander) Abhinandan Varthaman was part of in the clash with Pakistan after the February 2019 Balakot air strike. The remaining three MiG-21 Bison squadrons that the IAF has will be phased out gradually by 2025. Post that, it will start phasing out the six squadrons of ageing Jaguars in the early 2030s. The Mirage-2000s and MiG-29s will follow soon after that.
