Israils are the best integrator in the world , their packages to upgrade mig 21 was very potent , the sukhois have the problem with maintenance otherwise Israili components can be integrated very well ...and he said Russian never shared codes with India .... the only thing which russia never shared was the data links and that was the problem ....but BHEL has some good progress in that field other wise Israeli jammers can be easily modified as per customer requirements ... Sukhois are not the only jets using Israeli equipment and India is not the only country ... when we bought Sukhois Russia was in such a bad state economically that they cant break the deal of 280 aircrafts for just radar codes
Sukhois uses Indian mission computers just to make sure different component speak to each other .... If thats the problem then how can a Russian aircraft talk to ISRAELI AWACS
