Explanation From Original OP:

The Mikoyan-Gurevich Ye-8 was a Soviet prototype fighter designed to replace the MiG-21, which it never did because it was a bit ass. Nevertheless, in its own eccentric way, it’s probably one of the sexiest Soviet fighters ever designed - it really does look like the illicit lovechild of a Typhoon and a MiG-21, although the side schematics also remind me a bit of an F-16.
