White Paper: Real-Time Linux for Missile Defense — Inside the Golden Dome

Modern missile-defense systems like the Golden Dome depend on precise timing, rapid decision-making, and seamless coordination across a distributed network of sensors, interceptors, and command systems. Commercial operating systems cannot meet these stringent demands. This white paper examines how real-time Linux, combined with advanced debugging, scheduling, and system-level instrumentation, forms the backbone of a defense architecture where every microsecond matters.

The paper outlines how a real-time OS enables:

• Deterministic performance for tracking hypersonic threats and executing time-critical intercept actions.
• Coordinated distributed computing, ensuring geographically dispersed systems operate as a unified whole.
• High-fidelity simulation and testing, supporting both digital-twin workflows and mission-readiness assessments.
• Robustness and reliability, allowing mission-critical tasks to run uninterrupted even under extreme system load.
