Common Mistakes When Using “fission bomb”

FAQ
Frequently Asked Questions
Yes, in common usage 'atomic bomb' and 'fission bomb' are synonymous. 'Atomic bomb' is the older, more general term, while 'fission bomb' is more technically precise about the process involved.
A fission bomb uses nuclear fission (splitting atoms) for its explosion. A hydrogen bomb (thermonuclear bomb) uses a fission bomb as a trigger to create the extreme heat and pressure needed for a second, much more powerful fusion (joining atoms) reaction.
Yes. The 'Little Boy' bomb dropped on Hiroshima was a gun-type fission bomb using uranium-235.
Compared to thermonuclear weapons, they can have lower yields, but the critical mass required for the chain reaction imposes a lower limit on their size. Modern tactical nuclear warheads are still relatively large and heavy devices.
