FOAB (Father of All Bombs)
Russia · 2007 · claimed 44 t TNT (unverified) · conventional high-explosive
Overview
Russia calls it the most powerful non-nuclear bomb (claimed ~44 t, unverified; thermobaric).
With a claimed 44 t of TNT equivalent (analysts question the figure)[1], the FOAB (Father of All Bombs) is 341× smaller than the Hiroshima bomb. It is a conventional high-explosive weapon that releases its energy through chemical reactions, not nuclear processes. [2]
Effect radii not shown
The FOAB (Father of All Bombs) is a conventional (non-nuclear) weapon. The nuclear blast and thermal scaling laws this site uses do not apply to chemical explosives, so no effect radii are shown. See the methodology page.
