The SRB42 was fueled by energy-efficient, yet hazardous, radioactive, explosive liquid metal from four slug tanks in the center of the ship. Upon entering the engine, the fuel was mixed with a reactant in an intermixer before being released into the primary thrust pressure manifold, where it was ignited to start a fusion reaction that broke down the fuel into charged particles, the resulting energy providing thrust. The engines used specialized vectrals to redirect thrust. Shortly after the first YT-1300s left the CEC factory, several cases of sublight engine power transfer conduit blowouts and drive system stalls became widely reported, but a thorough investigation attributed these to operator error. With proper care and maintenance, an SRB42 could last for decades, and many YT-1300s reta
