Post by p***@lycos.com I have seen various websites describing the Teller H bomb as both 2 and 3 stage. Which is correct?
So far as I know, all of the fusion weapons currently stockpiled are two stage weapons. There are also a few boosted fission-only weapons that appear to be still in service.
Of course, there is no reason not to run MULTIPLE fusion second stages radially off of a single fission primary, this could be simpler to implement than a 3 stage fisssion/fusion/fusion design might be.
Tsar Bomba might not need to be a 3 stage device, but could be 5 parallel 10MT fusion 2nd stages ignited by a single central fission device.
