So, earlier this week, I caught a glimpse of this over on Rostec's twitter https://twitter.com/RostecRussia/status/1415752043973812225
I almost feel like it's no coincidence they included that subtitle, as if they're challenging us in the aero community. :P
UPDATE: Just saw their page and they gave a glance at the front section of this unnamed fighter five hours ago as of this post. https://twitter.com/RostecRussia/status/1416809884817924102/photo/1
