Oh Bhai! Count the chickens after they are hatched. Induct few more squadrons of Tejas, update radar on Su30-MKI to homegrown AESA, export Astra Mk-Whatever like a/r/t-darter of denel then we can brag. Right now we have a science experiment on a dual pulse motor. Make it a weapon and prove it.
As far as F-16 goes, its old and getting older. Chinese weapons are made-in-china, made-by-china and made-for-china so you know what its quality will be.
Better get all our ducks lined up in a row. Su-30MKI needs a new radar like right now. And Mig-21 needs to be retired 30 years back.
Su 30 MKI is all set to get new AESA by 2025. It will get ultra medern Cockpit with fifth generation features including Artificial intelligance which will guide pilot how and when to shoot missile what maneuvers to be done in case of dog fight etc.
