Su-57

Russian media announced on Friday that it had significantly improved the stealth on its Su-57 fighter jet by applying a coating to the glass canopy on the cockpit, as well as similar upgrades to its Tu-160 nuclear bomber.
But Russia’s Su-57 isn’t nearly stealth by US or even Chinese standards, and a coating on the glass won’t save it.

But none of those jets, including the Su-57, which Russia explicitly bills as a stealth fighter, are considered that stealthy by experts contacted by Business Insider.

While Russia’s Sukhoi fighter/bombers have enviable maneuverability and serious dogfighting capability, only the US and China have produced true stealth fighters.

Conspicuous rivets jutting out of the airframe and accentuator humps spoiled any possible stealth in the design, the scientist said.
