Yep.
Those bunkers had better far away and/or be very deep to have a chance.
If they are right under Moscow, and it gets hit with multiple high yield nukes, the seizmic damage may not cause a collapse to the hardened spaces, but it could easily trap them and destroy systems and services. In other words, it’s a massive death trap.
You don’t just cities with ground bursts. The USA doesn’t have the 5,10,15 megaton city buster anymore. The largest yield weapon in a missle we field is on the D5 trident its 475kt that small you airburst to make maximum use of the mach stem shockwave effect and to spread the heat flash as far and wide as possible. The USA retired our last lay down city buster the Gr8 with a 1.4MT yield they are all off line now. Even if you ground burst D5 warheads a hideously wasteful use of first strike silo busters on Moscow their subways are hundreds of feet deep and have multiton blast doors on the portals and tunnels. Go to Google type in Moscow subway blast doors then look at the NORAD looking massive blast doors that cover the exits those will take 200+ psi you would have to aim for one of those portals directly land your 200kt warhead within 500 feet of it for a 200+ psi blast. No Moscow is probably the only city on earth other than St. Petersburg that could take a direct hit by dozens of warheads and its people would come up a.month later and start rebuilding. They don’t even hide the doors you.can walk up.to.them in St Petersburg subways if you like. Air bursts don’t couple to the ground and induce seismic waves the impedance difference of the mass of air vs rock presents that you have to surface burst. Then you give up the shockwave and heat flash damages for a coupled in earth seismic waves in short surface bursts are only used to bust silos or leadership bunkers with a direct hit. There is a reason nearly every American warhead carries a altitude burst fuse and our new D5 have a radar enhanced air burst fuse to make them better at the air burst effects. You wide cities out with supersonic air shockwaves and the heat flash which sets fire to everything flammable in line of sight of the fireball for a ten mile radius. The trade off is ten mile wide fire storm or half mile wide hole in the ground city busting is done in the sky period.
