Yak-141 and Kikka are not F-2A equivalent vehicles.
A whataboutism false equivalence fallacy is not what you should focus on.
Production aircraft are also best compared with other production aircraft, and it shouldn’t be a “what about”.
This is not meant as an insult toward you. I just want reasoned positions to read.
Paper vehicles are being delisted in the game.
Prototypes [both combat capable and unfinished] are staying.
And of course production vehicles are staying irrelevant of which stage of production the vehicle was in [a slight reference to naval vessels].
