Pretty amazing. The US had similar weapons a long time ago supposedly to shoot down entire Soviet bomber formations.As part of the third stage of the exercise of non-strategic nuclear forces of Russia, footage of the MiG-31 aircraft being equipped with an R-33 air-to-air missile has been published. The R-33 medium-range missile was accepted into service in 1981, information about it is in the link to the video in the comments to the video. It is assumed that in this case, the R-33 missile is shown for the first time equipped with a special warhead, that is, in a nuclear version. Officially, the warhead of the R-33 missile is not reported.
I wonder what such a nuclear air to air missile would be used for today.
