MOP — weighs in at 30,000 pounds…the MOP hits the ground at supersonic speed before slamming its way toward a hardened target through layered subterranean defenses such as native rock, reinforced concrete, and steel plates.

The MOP is hitting the ground with at least 23 million foot pounds of force. It then survives that to penetrate through the defenses to successfully detonate.

That is some impressive engineering. My hat is off to the designers.

...

I would think that it would still need to detonate at a specific depth or when it hits a hollow area in order to be effective.
