Indications in recent months suggest that the upgrade program for India’s fleet ofSu-30MKI fighters is finally gathering pace. The Indian Air Force (IAF) has so far placed orders for 272 aircraft, of which 50 were delivered by Russia in 2002-2004 and 2007. Another 222 are to be supplied by the HAL Corporation; production under Russian license began at HAL’s Indian facilities in 2004. So far, more than 200 planes have already been delivered, and the Su-30MKI is the most numerous of the multirole fighters currently in service with the IAF.
