Re: Russia blocks sale of JF-17 with Russian Engines to Pakistan
Unlike USA; Russia will always prove to be a long term friend for India.
India probably put pressure on Russia to stop the sales of the J-10 from China to Pakistan; especially since Russia wants to sell billions of dollars worth of aircraft and other supplies to India.
The J-10 performance is about equal to the F-16 and maybe even the F-18.
It is based on 30 year old technology so it is no match at all for the F-22 and the Joint Strike Fighter. It is probably no match for the latest version of SU-30 that Russia is supplying to India.
However; the J-10 is probably equal to or even better than the Mig-29's that form the bulk of Indian air-force. And 150 J-10 will form an good counterbalance atleast defensively to the Indian air-force.
