Hello Nuclear War Simulator fans. Episode 4/6 of our video series is out now. This episode explores the damage nuclear weapons do indirectly. While the explosion, blast, and fireball have the capacity to destroy cities, fallout can destroy whole ecosystems. When an atomic weapon explodes, the ash and dust sucked up into the atmosphere rains back down on vast swathes of countryside, contaminatin…
Nuclear War Simulator's fallout model has been used in a scientific study commissioned by Princeton University. The Missiles on Our Land Project has utilized the NWS fallout model to track the different ways seasonal winds could effect the spread of radioactive ash and dust. This project specifically focused on modeling strikes on silo's in Montana, North Dakota, Nebraska, Colorado, and Wyoming…
Our third episode of the Nuclear War Simulator video series is now out. This time we cover the actual effects of nuclear weapons as they detonate. From the shock-wave to the thermal radiation, we go over the apocalyptic implications of a detonation in a major urban center.

A new update is available for Nuclear War Simulator. Along with bugfixes, new features include a data layer for average building heights, which will improve the accuracy of modeling damage to an urban environment. Build 399 New features and changes: -Visualization of single physical effects can now be disabled in the dropdown menus -New data layer added: average building height. The building he…
Hi everyone, a new update has just been released. Many many fixes and improvements! Build 394 New features and changes: - new buttons with text in the main UI overlay - added a name field to units - default blueprints and blueprints from mods are now protected from editing, deleting and renaming - added an option to cancel the calculation of fatalities. Fatalities calculation is automatically c…
Hi everyone, a new update has just been released. Build 391 New features: - blueprints of any country can be used by any other country in the placement panel, surface objects. This will make it much easier to give nuclear weapons to countries that don't have any nuclear weapons yet Bug fixes: - fixed incompatibility with Intel Laptop and some other GPUs - attack plans generated in the escalatio…
Today we are going to release a new update Here is the changelog: New features: - attack planer: in the counter-force targeting tool, when adding selected units, all added units will be selected by default, making the targeting easier Bug fixes: - alliances are now updated every time a country is added and does not require the name to be not empty. Previously, alliances were only working when a…
Hi everyone, the first update since the release is live! This update will solve a number of issues, especially for everyone who has problems calculating fatalities. Build 389 New features: - added an option to define a custom grid span for HYSPLIT - added an option to decouple effects visualization from the cursor: hold Left Shift by default - added version number to main menu Bug fixes: - fixe…
Nuclear War Simulator Out Now Nuclear war simulator is a detailed realistic simulation and visualization of large-scale nuclear conflicts with a focus on humanitarian consequences. It lets you design conflict scenarios and estimate the consequences using a population density map and realistic weapons effects. This software should help you answer the question: what will happen if Russia and the…
Nuclear War Simulator - Dev Log #5 Individual humans Simulating the effects of nuclear weapons on individual humans The nuclear war simulator can be used to simulate the effects of nuclear weapons not only on the population density but also on individual humans. You can place individuals on the map, move them on foot or in a vehicle and let them take different kinds of shelter. Each individual…
Nuclear War Simulator - #4 Dev Log Delivery systems The Nuclear War Simulator includes a number of modern nuclear weapons delivery systems. It simulates the most important characteristics of these delivery systems like the range and timing of the impacts. In NWS you can mount ballistic missiles, cruise missiles and gravity bombs on submarines, TELs, silos and on aircraft enabling the simulation…
Nuclear War Simulator - #3 Dev Log AI The Nuclear War Simulator can be controlled entirely by the user and also includes an AI that can control a country to launch nuclear weapons as a response to your actions. Each country has a political leadership figure with an AI that can be enabled and adjusted to respond to detonations on its territory and to missiles detected by early-warning radar and…
Nuclear War Simulator - #2 Dev Log Objects database Database of weapons and delivery systems The Nuclear War Simulator allows you to create detailed scenarios with full control over every detail of the objects deployed on the map. You can design warheads place them on missiles and mount them on delivery systems like aircraft or submarines. However, you can also skip all these steps and create a…

Moving human individuals, time-resolved fallout Human individuals can now move on the map and radiation dose from fallout is calculated and displayed in a time-resolved fashion. Civil defense situations and other aspects of survival after a nuclear war can now be simulated. There is a new UI for intuitive selection of shelter. Humans can move on foot or in a vehicle (if available). The speed an…
- Bug fix: increased the country index map resolution to match the resolution of the population density map. This should eliminate some of the fatalities counting inconsistencies in small countries - Bug fix: fixed two errors in the calculation of the biological effects terms. The calculated dose is now lower than before the fix - Bug fix: changed all bearing angles to the widely accepted conve…
Escalation scenarios generation tool The old scenario generation tool was greatly extended to quickly create scenarios with multiple escalation steps. The UI has options to set the escalation dynamics: - number of escalation steps - time between escalation steps - initial intensity - escalation speed - prioritization of military and civilian targets Objects of civilian infrastructure are now al…
This update includes a number of new core features and numerous minor improvements. HYSPLIT-based fallout model HYSPLIT is a detailed particle transport model that can be used for fallout deposition simulation.
