The Su-57, while technologically sophisticated, suffers from the challenges of integration and numbers. It possesses the "H101/-102/-103Byelka" radar system, utilizing three arrays (one forward, two side-looking) to provide 120-degree coverage, an impressive feat. However, the F-35’s sensor fusion is arguably a decade ahead in software maturity. The F-35’s ability to network (MADL - Multifunction Advanced Data Link) allows for "coopertive engagement" where the aircraft acts as a node in a vast network. The Su-57 pilot is more of an individual operator, reliant on their own sensors and G-forces, whereas the F-35 pilot is a battlefield manager.
