That is 60 meters of rock equivalent to reinforced concrete. So you need to dig that far into bedrock, not just beneath the surface. Well OK, you can count part of the overburden, say 20 to 25% if it is really thick. And 60 meters is just the depth that the bomb will penetrate to, you also have the effects of 2.4 tons of highly tamped HE to consider.

And below the bedrock means that the bunker will automatically be below the water table, so if it is cracked by a near miss flooding will be a major problem.

I've read that they are working on the next generation of penetrators which will be in the 3000lb-class or thereabouts which will have rocket boost to increase velocity and achieve greater penetration.
The smaller size and weight means that strike fighters will have a significantly increased ability to take out hardened, subsurface targets complementing the bomber force. I'm curious though if they will be able to cram it into the F-35 weapons bay?

Is the US military looking for a non-nuclear way to defeat ICBM silos? I Reckon A Nation-state war is getting a new contigency plan ^^
