Ayep, I'm afraid that's what we're looking at folks. I'm expecting between 10-80 ktons.
Think they'll figure out how to build a neutron trigger?
There's little doubt that given sufficient materials and funding such a device can be built, particularly given Kydaffi's previous attempts at doing so. Better questions would be directed as to how compact such a device can be built, and how *leaky* and otherwise susceptable to detection methods it might be.
See the Paräparat neutron trigger details of the *Virus House* device described in post #9, above....
As the bomb sphere drives itself down onto the armored nose cap, a plunger crushes the "Paräparat", and neutrons spray into the mass of uranium...
