This site is an educational historical reference. Weapon records use public sources and include uncertain or classified entries where exact specifications are not public.

The simulator uses historical detonation yields with simplified effect bands. Custom-drop casualty figures use a selectable population-density profile rather than live city population data. Advanced mode adds a wind-shaped fallout footprint for comparison, but does not calculate radiation dose.
