The Indian Air Force has retired the MiG-21 – the iconic Soviet-era fighter aircraft—that became the most produced supersonic jet in history and the backbone of the IAF. The Mig-21 trained generations of Indian Air Force pilots and defended India’s skies for six decades. Recorded around Mig-21’s farewell at Air Force Station, Chandigarh, this special episode of In Our Defence with national security expert Sandeep Unnithan dives into the jet’s history, upgrades, combat stories, the debate over safety, and its legacy. Host Dev Goswami and Sandeep unpack how a 1960s Soviet interceptor became India’s backbone, why it attracted the “flying coffin” label, what the Bison upgrade really changed, and how the MiG-21’s dominance shaped IAF training and doctrine.
