India must pursue Su-57
Indian Air Force (IAF) has restarted its two decades old quest for replacement of decades-old Russian fighter jets through a competitive tender. IAF is still relying on the Russian single engine MiG-21s and twin-engine MiG-27s. These aircraft are still part of the IAF’s inventory even when most of the air forces have retired them. This is only because IAF has not been able to replace them.
