SU-30MKI`s not initially designed to carry nuclear or strategic weapons, but newly developed IAF will receive 40 upgraded Su-30MKIs capable of carrying the BrahMos cruise missile possibly by 2012.
In addition, there are also plans to integrate the nuclear-capable Nirbhay missile with the aircraft as well.
In May 2010, Russia had won a large contract to upgrade 40 Su-30MKI fighters with new radars, onboard computers, electronic warfare systems and the ability to carry the BrahMos missile.
The first two prototypes with the 'Super-30' upgrade will be delivered to the Indian Air Force in 2012, after which the same upgrades will be performed on the last batch consisting of 40 production aircraft.
India is planning to upgrade its Su-30MKI fighters with Russian Phazotron Zhuk-AE Active Electronically Scanned Array AESA radars.
