EDIT: It'll never happen. It wasn't a mass-produced bomb. Same reason we won't get the A-bomb. It wasn't common, and it wasn't standard. It was a 1-off. (generally speaking, that is, I don't mean "there was only 1")
It wasnt as rare as you would think, it was used on 40 or so occasions by 617 Squadron. They were used against targets that were resistant to normal bombs such as aquaducts, u boat pens etc. They worked by being streamlined so they could fall at supersonic speeds when dropped from 20k or so, digging deep into the ground and then setting off the explosive to actually create an earthquake. The fins are made to spin the bomb very very fast to keep it accurate and help it dig into the ground. The charge to weight ratio is quite low compared to the high capacity bombs, but the charge is very powerful "torpex" explosive.
The smaller tallboy bomb weighed 12,000lb or so and was used something like 400 times, including sinking the Tirpitz.
Barnes Wallis, the designer of the bouncing bomb, designed both the tallboy and grand slam.
If modelled properly, it would obliterate a reinforced HQ in AH.
