This 50-page DIA reference report surveys aneutronic fusion for advanced space propulsion. It compares rocket performance, radiation burdens, confinement methods, and fuel cycles, while stressing that practical fusion had not achieved break-even and that high-temperature ignition, plasma losses, shielding, fuel consumption, and system engineering separate theoretical performance from an operational spacecraft.

This 36-page DIA reference report reviews aneutronic-fusion propulsion concepts, including plasma confinement approaches and prospective aerospace applications. It frames the material as a development roadmap: terrestrial fusion remains technically and economically unresolved, while any transition to space would require major advances in mass, power, energy recovery, fuel storage, engineering, and demonstration.
