They are testing missiles one after another no matter chinese or some other brand.And only god knows what our politicians are busy with.Our air force is getting out of date.Yes I agree su,s, mig-29s, Mirage-2000 are up to date but the strike force which consists of mig-21 to mig-27 are outdated.lca project is delayed.From last 8 years our politicians can not finalize the deal for 126 fighter aircrafts which iaf needs as soon as possible stop the decline in squardon numbers.Mig-35 and Eurofighter are the best options.Mig even has offerd the technology transfer.then why such delays.
