Building a Ballistic Fire Control Simulator with Python, C# and Redis

The author built BALISTIC V5, a real-time ballistic fire control simulator using a microservices architecture with a Python/Flask frontend and a C# physics processor communicating via Redis Streams. The physics engine implements Euler method trajectory simulation with drag, Coriolis deflection, and live air density from weather APIs, supporting multiple weapon systems with blast zone visualization on a satellite map. Key lessons include the limitations of Euler simulation at high velocities and the importance of using real-world muzzle velocity data to match NATO ballistic tables.
