I searched in the forum and found nothing about crew complement of the IS ether ships.

Is it roughly the same number of tripulants of the wet navy ships of the same size?
Is it a lower number on the account of life support systems? And if it is lower, how much lower? 1/2? , 1/3? , 1/5?

Example: HMS Indefatigable
Size:
Length 590 feet overall, displacement loaded 22,080 tons.
Crew 790.

I would compare it with:

HMES Gauntlet Class Battlecruiser
Size:
Length 592 feet overall, displacement loaded 22,100 tons.
Crew? 1/2 = 395 1/3 = 263 or 1/5 = 158

I know it's a fluff question, but it answers a lot of small detail about the inside of the etherships.
