These underground bunkers that are in Iran are fortified against bunker buster bombs. A 1 to 10 kiloton surface burst will produce the necessary overpressure to completely destroy these bunkers.

I don't know. I think we have perfected the JDAM system to the point where we can keep dropping 2000-pounders into the same hole until we hit magma.

Why do you need three bunker busters carried by plane and flown by a pilot to destroy a underground target with no guarantee your bomb has detonated? It is easier to fire one nuclear tipped missile to completely destroy underground target in which you are guaranteed success.

I just Googled "1 kiloton nuclear blast data".

This link came up:

It's an Adobe style page, but close to the top, it has a table of contents that looked interesting, and the title that shows up on the link is:

"Effectiveness of Nuclear Weapons Against Hard and Deeply Buried Targets"

...... kinda what this thread started to be about.
