@jshm2 A nuclear bomb fireball is more than hot enough to melt granite, and the shock-waves would easily travel a long way through solid rock, but the bomb would likely need explode against the rock to be really effective against deep tunnels. Not high in the air above the target as these weapons are designed to be used.

However, I would agree it is probably impossible to find and completely destroy installations deep below ground and designed to withstand any likely attack. The associated surface plant and vehicles are obvious targets though.

Were the missile launchers in this incident fixed installations or mobile?
