Everything I have read about the Su-75 compared to the in service stealth fighters (F-22, Su-57, F-35, and even the J-20) makes me think it is either vaporware or at least very over promised.
Example would be range, admitted the SU-57 has long legs compared to the ‘22 and 35 but it is HUGE.
Where is the ‘75 going to put all the gas for a 1900 mile range, particularly with 5 weapon bays?
Also the degree of stealth of the ‘57 is still being discussed and for the J-20 my very limited understanding of the design elements involved to produce a stealthy fighter I always come back to those canards and how to limit reflections from them.
It just seems like all the effort stealing or recreating the intakes from the F-35 just goes out the window.
Sorry for the ramblings, thank you for you indulgence.

I would be interested in a comparison of stealth features. From what I understand, the F35 is not stealthy from behind.

No apology necessary. Thank you for your interesting observations and indulging us.
