Indeed, but the Russians claim that they are stealthy, after all, even the Su-37 has a significantly reduced radar signature. I guess we should give them the benefit of the doubt. If we don't consider these a/c, what are we left with? The F-22 and the F-35? If the S-37 still has some hope of one day leading to an operational fighter jet, the MiG 1.44 is deffinetely not going anywhere, as the Russian AF does not want to have anything to do with the a/c.
Pacifism only works if EVERYBODY practices it
