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.

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.

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.

Detonating at the desired depth and destroying the target would define success.

My point being that the bomb can survive an impact of 23 million foot pounds of energy and have its internal control circuits intact to detonate as designed is amazing.

Consider that the bomb is going to decelerate from more than 761 miles per hour to zero in less than a second. That is a lot of energy to be dissipated and survived.

Think your iPhone would still be able to play Angry Birds after that kind of shock?
