36 jets for 10 includes weapons,infra,training,life cycle costs... and its availability rate is 80-90 while our own MKI's would cost us more than Rafale with Weapons, Maintenance and poor availability rates. Qatar and egypt paid 7 billion for 24 Jets, Rafale is not cheap.. and its damn capable fighter which is going to change any scenario during the war.
We don't need to replace the 400 Jets with rafale. most of the fighter we need to replace for the Low category Jets like Mig-21 and 27s and that's where Tejas comes in. Its very expensive to replace them all with a Imported Jets... on paper Lca MK1A looks very good, if HAL does the miracle by next year with AESA on Tejas, there's no way IAF going to ignore it.
the idea is to self reliance scraping Tejas is only going to put us behind, then why are we buying Rafale??? because we need the Tech and assistance ( back door deals) for the dev of AMCA.
See our goal is not be reliant on others in the future... FGFA will be top and AMCA will be medium category and LCA mk2 will be the low point defense fighter.
