Nuclear war simulator is a detailed realistic simulation and visualization of large-scale nuclear conflicts with a focus on humanitarian consequences. There are currently over 13000 nuclear weapons on this planet of which over 9000 are in military stockpiles. This software should help you answer the questions: what will happen if Russia and the United States or India and Pakistan use their arsenals? What will happen to the population of a country in a nuclear war? What will happen to me and my family?
You can design warheads, missiles, and carriers, place them on the map and execute attack plans to tell a credible story about how nuclear conflicts play out and what the consequences are. Using a high-resolution population density map and realistic weapons effects like blast, heat, and radiation you can make an estimate of how many people will die in a conflict. Individual humans can be placed on the map, travel, and take shelter to analyze the effects and estimate injuries and survival probability.

Nuclear conflict scenarios

You can design realistic large-scale scenarios between major powers with thousands of warheads. Scenarios can be created manually where you can assign each warhead individually or with the assistance of an AI. A database of all known nuclear weapons deployed today and some historical nuclear weapons is available for faster scenario creation. You can download scenarios created by other people and upload your scenarios to the mods.io server.

Realistic effects of nuclear weapons

The simulation includes a high-resolution population density grid. The effects of blast, heat, fires and radiation are calculated and visualized for each population cell to estimate fatalities. The destruction of military targets is simulated using a model considering the CEP of the weapon, target hardness and cratering. The amount of burnt fuel and produced soot are also calculated to estimate the effects of nuclear winter using a simplified model. Integration with the particle transport model HYSPLIT is available for detailed fallout simulation.
You can place yourself, your family, and your friends into the simulation to estimate the expected injuries and survival probability.

Design and placement of objects

Using an intuitive UI you can design warheads, and place them on missiles and into silos, on aircraft, TELs, and submarines.
You can then place the forces onto the map by simply clicking on it or importing real-world locations from KMZ files. A database of objects at their real-world locations is available for some countries for easy scenario creation.

Modding and interfaces

The simulation supports some basic modding of unit textures, loading screens and background music. It is also possible to share unit blueprints and scenarios with others.
If you have simulated a conflict in another tool you can import the list of detonations as a simple CSV file to calculate the humanitarian effects. You can also export the list of detonations together with the burnt soot into other tools like detailed climate simulations. An interface to HYSPLIT can be used to calculate fallout deposition and visualize the results in NWS.
