The Indian Air Force (IAF) has retired one of its three remaining squadrons of the aging MiG-21 fighters. The No. 4 Squadron based at Uttarlai in Rajasthan has phased out the latest MiG-21 Bisons.
These aircraft will gradually be replaced by the indigenous light combat aircraft (LCA) Mk-1A aircraft. The IAF had already phased out the Bisons of the Srinagar-based No. 51 Squadron a year ago.
