That is because one is a bigger fighter and one is smaller. Have you ever heard of a low and high mix?Well if J-10 indeed has so many mythical capabilities then why churn up home made RU Flanker lookalikes aka J11B.
Why don't you actually read the link I posted a while ago.Point me to a poster/link who said or mentioned SC speed==1.5 Mach which you were claiming otherwise,you have no proofs to back your claims .we all are waiting for you to come up with proper citations.
And what do you actually know about weapons specs and how objective or tested this claims may be?Co incidently that 'no one' happens to be you alone ,Afaik we discuss weapon specs which are meant for military use and objectives .
So what! You are the one who have to bring up the Raptor here. As if you didn't know that other planes by the academic definition of supercruise, have already done it (Concorde, BAC Lightning).Raptor is very much of significance for it is you who came up with a F-16(again is that related to the thread OH I forgot my bad J-10 and F-16 related true eh....) achieveing the SC in CLEAN config (I am scared),I mentioned the Raptor for it is the only bird out there which was made ground up to super cruise with mission critical combat load (although I have heard of EF and Rafael too having a limited capability to SC under certain config) .
We are talking about the J-10 here. The closest equivalent in weight, thrust and size is the F-16. Given an uprated engine, why can't it hit supersonic on dry thrust?
