B53 blast radius (9 Mt)

Last updated

B53 is a retired 9 Mt US bomb class, often described as a bunker-buster. On this globe it is a 9 Mt airburst so you can see a high-megaton disk without going to Tsar Bomba.

Educational estimate only. Blast and heat rings use simplified yield scaling. They ignore terrain, weather, shielding, and weapon design. Casualty counts use WorldPop 2020 residents on an approximately 1 km grid and ignore time of day, commuting, shelter, and evacuation. This is not a targeting or civil-defense tool. About the model.

Yield 9 Mt · 4.6 km (2.8 mi) optimum airburst · Cold War bunker buster

Ground ranges for B53 (9 Mt, 4.6 km (2.8 mi) optimum airburst) in this simulator.
Effect Ground range What the model means
Fireball 3.4 km (2.1 mi) Maximum luminous radius
20 psi 7.1 km (4.4 mi) Heavy destruction
5 psi 15.3 km (9.5 mi) Most buildings collapse
Thermal 28.3 km (17.6 mi) 3rd-degree burns
1 psi 35.4 km (22.0 mi) Windows shatter
Rings scaled to 1 psi. Yellow fireball, red 20 psi, orange 5 psi, gold thermal, blue 1 psi. Not a map of buildings.

Nine megatons is 600 Little Boys. Cube-root scaling still keeps the radius in the tens of kilometres, not continental.

The real B53 was not an educational graphic. This card exists so the yield ladder has a rung between B83 and B41.

Surface burst in the globe will add a simplified crater and more local fallout. The default card is airburst like most of the list.
