Ok let's give the benefit of the doubt, let's assume BURFIS and the APG-85 are exactly the same.
The question is which aircraft is more stealthier now?
- RAM paint on F35 will probably be more advanced than the one on TFX.
- TFX will still use 4th generation engine technology probably until mid 2030s.
- F-35 will have better frontal and rear radar reduction than TFX (until we get 5th gen engine tech)
Our S400s or TFX wouldn't be able to detect the F-35 first.
This was a stupid gamble. I hope next government sells the S400 to Ukraine, and we invest into SIPER and get the F35.
We didn't even get any technology transfer from Russia for the S-400, it was just another stupid political sabre rattling.
