Hi some great fools and great supporter of indian technology. You may pay trillion dollars for a product but no country in the world will sell the critical technology; Russian has been our laungatiya yaar as claimed by many great think thanks in defense; the fact is not a single aircraft or tank has been developed in India; those who talk of 286 and duo 2core should understand that aliens(if one believes) have far advanced technology than humans. This is for some babies in India, prior to LCA /Arjun tank we never had any strong R&D base; we used to import materials, tools, even design to integrate every parts; I hope some pandits who behave foolishly or make lose comments will understand meaning of R&D; the first product any where in the world is not perfect; with support from govt. the product takes perfect shape; we Indians think the first product is perfect product, wake up kuch gadhe log no first product is best product, it take years to reach perfection.
