Is it?Which is still on par with all the other platforms made to date.
I dont think that in peacetime Starfleet ships spend all that much time in space without regular port visits.
Something like this, otoh, is going to be either doing a lot of cargo hauling, which means that it wont be at rest for very long, or it will be doing longterm construction/reconstruction in pretty barebones environments.
I dont think the service conditions are comparable.
US SSBNs spend an average of 77 days at sea at a time, and then 35 days in port.As someone who's for rec areas on the general principle of 'they're up there for a long time, they're going to need some damn good R&R to avoid going stir crazy', I'm actually curious about what the specific numbers and study results are.
And thats with alternate Blue and Gold crews that alternate taking the ships out each time, giving the other crew time and opportunity for R & R.
Upwards of 3 months in a not!military ship seems like the sort of thing where you begin to pay especial attention to crew morale and conditions.
