i just drew up plans for a 1200 ton lab ship, it is three times the diameter of the lab ship in the core rule book, with the grav modules off it can rotate once in just under 20 second to produce a centrifugal force of 1 g, and it is 98 meters in radius, it has about 42 staterooms, three labs, 4 air/raft hangars, and a 95-ton cargo shuttle docked to its central docking ring. There are two versions of this spaceship. One is the Standard Tech Level 15 version for the 3rd Imperium setting, the other is a Tech Level 8 version for my triplanetary setting. I was making up a bunch of TL 8 versions of the Common Spacecraft that shuttle between Earth, Venus, and Mars in my setting, and I decided that since there was no artificial gravity for this setting, I'd create at extra large version of the Lab ship which could rotate at a full g of centrifugal force, since this would be the only ship with onboard gravity, everything else has zero g environments for the trips between the planets, as the reaction engines only provide acceleration from 1% to 6% of Earth gravity. Since I am doing all this work, I would like to submit it. I'll have the stats for this ship ready in a day or two. So if you are interested, how shall I submit it and where?
The 3rd Imperium Version will have a Thrust of 2g and a Jump of 2 parsecs. the shuttle will be used to skim gas giants, as the lab ship can't land.
