Yes, the Kinzhal is an ALBM. It is an Islander-M IRBM modified to be launched from a MiG-25. The Skybolt, which again we developed in the 1950s, had a speed of Mach 12. We abandoned it in favor of ICBMs and SLBMs.
And I doubt they destroyed any “underground bunker” with one. The video the Russians released claiming it showed the impact was obvious BS.
