In April 1946, the Council of People's Commissars ordered several design bureau, included that of Alexander Yakovlev, to develop a single-seat jet fighter to be equipped with a single Lyulka TR-1 turbojet engine. An afterburner is only a WEP on steroids anyway, really. Let's begin! On top of that, the F-94 which had an afterburner IRL was passed to development because its performance fits the game so I don't see why the worse Yak-19 would not fit. Wait, the Yak-19 has an afterburner! Yes, that's true, but it's an early afterburner that barely got its top speed above 900 kph. I hope one day both lines flourish, so that newcomers and everyone have a reason to fully grind those lines for being worthwhile for having everything a tier 5 line needs besides only to complete the Russian tech tree. Currently, the only viable jet line is the MiG line because it has proper early and top tier jets while Lavochkin and Yakovlev are left behind, which is another reason why I'm suggesting this. The Yak line is currently missing a proper early jet and top tier jet (fspeaking as of now, the Yak-23 is coming) so to fill in the gaps I'm suggesting the Yak-19 and suggested the Yak-50 1949. Currently, the Yak line only has 4 jets, 3 of which are hard to master for new jet pilots because they're not quite at the performance of what is conceived as a jet (Yak-15, Yak-15P and Yak-17) and the Yak-30 which is good but also unfriendly for jet newcomers due to its high BR.
Recently, the Yak-23 has been revealed on the dev server which caught my attention and made me rethink of suggesting the Yak-19.
I wanted to write a suggestion about the Yak-19-II long ago but then I felt de-motivated.
