Ho Chi Minh City city centre sits 741.3 km from Bangkok, the most plausible strategic target in the area (low targeting confidence). Modelled strike: 150 kt airburst.
Estimated survival chance at city centre: 99% · Estimated metro fatalities: 257.6K, injuries: 310.2K
What a strike on Bangkok would mean
A 150 kt detonation produces a fireball 490 m across in radius. Reinforced concrete fails out to 1.8 km (20 psi). Most residential buildings collapse within 3.7 km (5 psi), and windows shatter dangerously out to 8.2 km (1 psi). Anyone in line of sight within 5.2 km suffers third-degree burns from the thermal pulse.
An airburst maximises blast damage but produces minimal local fallout, so for Ho Chi Minh City the dominant risks are blast and thermal effects rather than radiation.
Most plausible targets near Ho Chi Minh City
| Target | Type | Distance | Assumed yield | Confidence |
|---|---|---|---|---|
| Bangkok | city | 741 km | 150 kt | low |
| Sanya naval base (SSBN) | military | 878 km | 455 kt | high |
| Singapore Changi | airport | 1091 km | 150 kt | medium |
| Port of Singapore | port | 1107 km | 300 kt | high |
| Hanoi | government | 1138 km | 150 kt | low |
Key blast radii (150 kt airburst)
| Effect | Radius | What happens |
|---|---|---|
| Fireball | 490 m | Complete vaporisation |
| 20 psi blast | 1.8 km | Hardened structures destroyed, ~100% fatalities |
| 5 psi blast | 3.7 km | Most buildings collapse, widespread fatalities |
| 3rd-degree burns | 5.2 km | Full-thickness burns to exposed skin |
| 500 rem radiation | 2.1 km | Lethal dose without medical care |
| 1 psi blast | 8.2 km | Window breakage, light damage, glass injuries |
How Ho Chi Minh City can prepare
With a population density of 4,600 people/km², Ho Chi Minh City'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.
