I'm not sure is this the right place to post, but I couldn't find better.
Does anyone knows is this a whiff or it was an actual project that never went further from drawing board? I found this pic marked as Project 3 (?) and, as you could see, it look like a heavily upgraded MiG-25. It was among drawings made in similar style, but all were actual aircrafts and prototypes (Chinese Air Force J-7, J-8, J-11, etc).
