>>91024190>>91024236I tried to estimate this a while back by assuming the ships have roughly the same crew/length ratio as a modern aircraft carrier and scaling up accordingly.
Carriers actually have a crew of about 6,000 people and I guesstimate that the Galra cruisers are about 4-5 carrier-lengths, plus that huge engine section and the weird nose, so a ship that size by modern standards would have like 30,000 to 40,000 people on it.
The Galra are more advanced than that, so we can assume their ships are highly automated even before accounting for the robotic crew, so the numbers could be significantly smaller, say 25,000 to 20,000. The robots definitely seem to make up the majority of the crew, anywhere from 70% to 90% of the total crew.
I end up with between 7,500 and 2,000 living Galra crew members. I haven't bothered using that figure to find how many Galra the Paladins have blown up, but it's A LOT.
