[2020] MiG-21bis missing Kh-66 AGM

Hello

This is not a bug. This weapon could only be carried on aircraft equipped with PFM level of guidance radar similar to that of the Fireflash on Swift F.7.

The developers have already revived this situation and confirmed that our MiG-21Bis could not fire it. Only the variants such as MiG-21PFM could.

Forwarded to the developers for review.
