I read a little about these a while back. Dont even remember the source.
I believe they are designed to be low yield devices capable of penetrating into deeply dug in installations and destroying them.
Just the perfect solution to Iran, North Korea, and other traditional enemies who have invested millions in underground military infrastructure.
I know most people get a knee jerk reaction to nuclear development, but it seems this is the only known way to destroy these types of installations. (I could be wrong, however...havent been keeping up lately.)
You are absolutely correct, JM. It IS the only way. JDAMs are good, but entirely underpowered for this application.
The goblins need to know that there's no point in hiding underground; we need to make sure that the world knows that a nuclear war is not something that can be won, either through hiding or shield spoofing. As it is now, we are at a disadvantage until we have this development complete. Restoring the balance of MAD is what will keep us safe from traditional enemies while we dig out the islamofascists.
Watching the DNC convention in Boston, I witnessed BJ slam GWB for wanting to develop these. He still doesn't get it; he actually helped create some of the need for these tools.
1 kiloton to 5 kilton. Most likely the "Dial a yield" setup of the B-61.
