Meaning and Definition
A type of nuclear weapon that uses both nuclear fission and nuclear fusion reactions to produce an extremely powerful explosion, also known as a hydrogen bomb or thermonuclear bomb.
In anthropology, it also describes a social organization model observed in some primate and human societies where group size and composition are fluid, with subgroups (fission) periodically merging (fusion).
Dialectal Variation
British vs American Usage
Differences
No significant differences in usage or definition. The technical term is identical in both varieties. The anthropological sense is equally rare in both.
Connotations
Strongly negative connotation in the nuclear weapon sense due to association with mass destruction. Neutral, descriptive connotation in the anthropological sense.
Frequency
Extremely rare in everyday language in both regions. Slightly higher potential frequency in US media/politics due to historical and geopolitical context of nuclear arms discussions.

FAQ
Frequently Asked Questions
No. An atomic bomb (or A-bomb) uses only nuclear fission. A fission-fusion bomb (H-bomb) uses a fission explosion to trigger a much more powerful fusion reaction, making it vastly more destructive.
It describes social structures, like those of chimpanzees or some hunter-gatherers, where a large community frequently splits (fissions) into smaller foraging parties and later reunites (fuses). This is a separate, metaphorical use of the terms.
The fission bomb (atomic bomb) was developed and used first during World War II. The fission-fusion bomb (hydrogen bomb) was developed and tested several years later, in the early 1950s.
The order reflects the sequence of reactions inside the weapon: a primary fission stage ignites a secondary fusion stage. Reversing the terms ('fusion-fission') could in theory describe a different, even more advanced theoretical design, not the standard H-bomb.
A type of nuclear weapon that uses both nuclear fission and nuclear fusion reactions to produce an extremely powerful explosion, also known as a hydrogen bomb or thermonuclear bomb.

Learning
Memory Aids
Mnemonic
Think of it as a bomb in two stages: first it SPLITS atoms (fission), then it SQUEEZES them together (fusion) for a much bigger bang.
Conceptual Metaphor
ULTIMATE POWER IS FISSION-FUSION (for the weapon sense); SOCIAL FLEXIBILITY IS FISSION-FUSION (for the anthropology sense).
