> No thermal signature. That's isn't how thermodynamics works. It could have a reduced thermal signature but infrared cameras are so absurdly sensitive so it isn't obvious to me that a reduction would be a big advantage. > Potentially redundant drive Diesel-electric would have the same redundancy advantages: https://oshkoshdefense.com/engineering-solutions/propulse/ https://oshkoshdefense.com/engineering-solutions/propulse/ > No diesel fuel to catch fire. Diesel is relatively hard to get to burn as liquid fuels go... lithium chemistry batteries aren't particularly known for being fire free.
