We hear that HGVs are invisible to radar on account of the atmospherically generated plasma shroud, but wouldn't that same shroud reveal extremely precise coordinates to a 1st tier infrared sensor? | |
If EM doppler wasn't enough for ranging, triangulation would be. |
After further consideration, giving the tube / "barrel"(as someone put it) more credence

That vid has slowmo take and you can see the flame jet out of the ground before the projectile / missile, as could be expected of a tube launch (not a sealed barrel iow). Initially I had puzzled over the metal screaming sound preceding the visible launch. That's the sound of all that thrust and maybe the missile itself moving up out of the tube. Guessing 100m depth. just a working hypothesis.

Is it possible they are being launched from silos with a great depth ? It would make sense from a survivability pov, and would make the apparent acceleration (I'd assumed starting just under surface) a little less insane. Nah, idk, just a thought.
