See Abwehran Fusion Engine for inner workings.
Developed in AF 260 (YE 31) as the most durable form of the Fusion Engine, Capital Fusion Engines have low acceleration but high power enabling some of the largest ships Abwehrans have built to reach at least 0.2 of the speed of light.
Accelerations are based on reaching Maximum Attainable Velocity in an hour.
