Blueprint for a Deuterium–Helium-3 Magneto-Inertial Fusion Rocket: A Space-Ready Propulsion Architec

This work introduces the first complete blueprint for a Deuterium–Helium-3 Magneto-Inertial Fusion rocket. The paper combines contemporary plasma physics with spacecraft engineering into a plausible, phased development roadmap — from laboratory-scale pulsed FRC testbeds to interstellar-class vehicles. The design integrates: A pulsed Field-Reversed Configuration (FRC) reactor core. Direct magnetic nozzle exhaust for propulsion. Performance calculations confirming feasibility (fusion dominance over bremsstrahlung losses, exhaust velocity ~0.15c, ISP ~4.6 million seconds, thrust-to-power scaling, radiator requirements). A four-phase roadmap from lab demonstration to a 500-tonne starship-class system. This publication establishes a historic first: a spacecraft-ready aneutronic fusion propulsion architecture using D–He³, bridging the gap between laboratory plasma experiments and interstellar exploration.
