@Manindra Let's be clear about one thing - US is an unreliable defense suppler in the eyes of the Indian establishment - both Military and Political - and we have many reasons to believe so - France’s steadfastness as a military ally contrasted strongly with that of the United States, which stopped F-16 deliveries to Pakistan (but kept the money) when it found it expedient to do so, and slowed or vetoed delivery of components for Light Combat Aircraft that India was developing. And, of course, the 1998 arms embargo, decreed by the US after India’s nuclear test in May of that year, left a very bad taste in Indian mouths. France, on the contrary, was the only Western nation not to impose sanctions on that occasion.
It was India’s real reason for eliminating Boeing and Lockheed Martin from the fighter competition; India has resolved, to buy only second-line equipment from the U.S., such as transport (C-17, C-130J) or maritime patrol aircraft (P-8I). Vital weapons such as missiles and fighters, when they cannot be locally produced, will remain the preserve of France and Russia.
