nuclear bomb
B2Formal, Technical, Journalistic
Definition
Meaning
A highly destructive explosive weapon that releases enormous energy from nuclear reactions—either fission (atomic bomb) or combined fission and fusion (thermonuclear/hydrogen bomb).
By extension, a symbol of ultimate destructive power, catastrophic threat, geopolitical power, or the potential for total annihilation. Also used metaphorically for something with sudden, overwhelming impact.
