Wrong, the AMCA avionics is nothing but in paper, infact the avionics in Su57 is 5 generations ahead until AMCA becomes operational. The Su57's kinematic performance is also much superior.
A lot of AMCA tech will enter testing soon.
Surpass in every way? The Su57 is the best fighter on the planet right now, you gotta be less delusional about said claims. Su57 had superior aerodynamics, control surfaces, twr, suoermaneuverability, supercruise, longer combat radius, bigger internal weapons bay, AI and ability to command drones and can even act as mother ship, better multi band senor suite, a decade more mature and proven tech by the time AMCA get deployed, blanketed claims like hold no meaning. Don't get me wrong, the AMCA is gonna be a great jet but claims like AMCA is gonna surpass the Su57 in every way is peak delusion from lack of understanding both's capability and maturity.
AMCA's stealth and avionics will exceed the Su-57 by a significant margin.
AMCA will also have supermaneuverability, supercruise etc.
Yes, AMCA will also act as a "mothership" and carry a multi-band sensor suite.
But no, a lot of technologies for AMCA will be proven on LCA Mk2 and MKI. The Russians don't have a bridge program of the sort we do. So AMCA will have mature tech when it's ready.
