Nuclear Simulations
Physics-based educational tools for understanding nuclear weapons effects. All warhead and delivery vehicle data is sourced from the HiWars equipment database.
Blast Effects
Select a nuclear warhead and click anywhere on the map to instantly visualize the fireball, radiation, thermal, and pressure wave zones.
Launch Simulation
Choose a country, warhead, and delivery vehicle. Set a launch point and target to watch an animated ballistic trajectory.
Nuclear War Simulation
Model a full-scale nuclear exchange between multiple nations — warhead allocations, strike timelines, and global fallout.
