The *Ohio*-class displace 18750 tonnes submerged, and so has a volume of
about 18,250 m^3 (sea water being slightly more dense than pure water),
which is 1300-1350 DTons, depending what size of DTon you prefer.
Complement is given as 155, comparable to that of the *Zumwalts*.

The *Los-Angeles*-class displaces 6,927 tonnes submerged, and thus has a
volume of about 6,745 m^3, or 480-500 DTons. Listed complement is 129,
rather more per ton than the *Ohios*, I'm guessing because crew
requirements for reactors don't scale linearly, and because they have a
need for more fire control and situational awareness systems and staff.

This does imply that damage control on Traveller spaceships is limited
because of the limited man-power. On the other hand, if you're using the
CT spaceship rules, from my recollection there's not a lot of in-combat
damage control to be done.
