Via Ry. Meet MOP, Boeing's new bunker-busting super-bomb:
The 20-foot-long bomb that weighs 30,000 pounds — much heavier than the 21,000-pound MOAB, or Massive Ordnance Air Burst bomb, unveiled in the prelude to the Iraq war.
...
MOP will go a lot deeper — 200 feet of 5,000 psi concrete. MOP pulls it off by not being all that explosive — less than 20% by weight, compared to almost 90% for the MOAB. That's because bunker-busting bombs need very thick casings to survive the effects of impact.
...
Potential targets for MOP or other deep penetrators would include the Iranian underground centrifuge cascade at Natanz and the heavy-water reactor complex under construction at Arak.
Ry told me about it yesterday. I thought about for a few seconds and announced, "I'll bet I could defeat it with 100 feet or less of concrete." I explained and Ry countered with a solution to my defense. I modified my defense and defeated that as well. About midnight last night I woke up with a solution to my modified defense--use more than one bomb per target. I thought about that solution for a few seconds and came up a defense against that attack plan too.
I incredibly impressed someone has designed a non-nuclear bomb that will penetrate 200 feet of high end concrete. But with a smartly designed bunker that may not enough. But my thought process over the course of just a few hours should be a lesson to Iran, don't count on your bunkers being safe should you continue on your current path. You designs could be made obsolete in a matter of days. Can you redesign and rebuild as fast was we can come up with new attack plans? And you won't know our plans until after the bombs start dropping.
