Omaha city centre sits 15.5 km from Offutt AFB (STRATCOM), the most plausible strategic target in the area (high targeting confidence). Modelled strike: 800 kt surface burst.
Estimated survival chance at city centre: 99%
What a strike on Offutt AFB (STRATCOM) would mean
A 800 kt detonation produces a fireball 1.1 km across in radius. Reinforced concrete fails out to 2.5 km (20 psi). Most residential buildings collapse within 5.1 km (5 psi), and windows shatter dangerously out to 11.5 km (1 psi). Anyone in line of sight within 10.3 km suffers third-degree burns from the thermal pulse.
Because military and hardened targets are typically attacked with surface bursts, fallout matters here: with prevailing winds the dangerous plume would stretch roughly 134 km east of ground zero. Omaha city centre lies outside the projected corridor under these wind assumptions.
Most plausible targets near Omaha
| Target | Type | Distance | Assumed yield | Confidence |
|---|---|---|---|---|
| Offutt AFB (STRATCOM) | military | 15 km | 800 kt | high |
| Whiteman AFB (B-2) | military | 347 km | 455 kt | high |
| Warren silo cluster NE (NE border) | military | 607 km | 800 kt | high |
| Cushing oil hub, OK | energy | 591 km | 150 kt | medium |
| Chicago O’Hare | airport | 672 km | 150 kt | medium |
Key blast radii (800 kt surface burst)
| Effect | Radius | What happens |
|---|---|---|
| Fireball | 1.1 km | Complete vaporisation |
| 20 psi blast | 2.5 km | Hardened structures destroyed, ~100% fatalities |
| 5 psi blast | 5.1 km | Most buildings collapse, widespread fatalities |
| 3rd-degree burns | 10.3 km | Full-thickness burns to exposed skin |
| 500 rem radiation | 2.8 km | Lethal dose without medical care |
| 1 psi blast | 11.5 km | Window breakage, light damage, glass injuries |
How Omaha can prepare
With a population density of 1,100 people/km², Omaha's outcome would hinge on the first hour. The guidance is identical everywhere: get inside, stay inside, stay tuned. A basement or the core of a large concrete building cuts fallout exposure by a factor of 10 or more, and radiation decays fast — dose rates fall ~90% within the first 7 hours and ~99% within two days.
