I am using the Catalyst edition of TM to design units and have a question about the crew requirement for DropShips (presumably this would also apply to large units like JumpShios, WarShips etc). On page 189 the Aerospace Control Systems Table mentions that the minimum crew of a Military DropShip is 4 +1 per 5000 tons, so a 9700 ton Overlord would have a minimum crew of 6, plus 2 officers according to the footnote.
My question is, as DropShips operate for days and weeks at a time, does this figure allow for crew rest? Most modern seagoing vessels (the closest current equivalent of DropShips) operate on a watch roster system with three shifts. Does this minimum crew figure take this multiple-shift arrangement into account, or is this to calculate the crew for each shift and should therefore be tripled?
