The question about is money is no doubt dependant on our economy..we need to improve it no argument about that.
But every time if u go for f16, stating that ,other aircraft will need a new infr...that is illogical
as u have mentioned that,..we should invest in J10...again it will require it's own infra.....
the thing is we should no be dependant on USA...and no matter how much we improve jf17..it will remain a light weight fighter..which does not fulfil our requirement completely....we need medium and heavys..for future
