Spaceships: Escape to the asteroids

Whoops. I'd started trying a SM+7 design, and forgot the bunkrooms were larger when I went to SM+8.

Going down to a single bunkroom space, I can also swap out the Open Space for total life support.

There are some corners you could cut if you're comfortable with using smaller systems. You could use a half-size NSW rocket, or two 1/3 size, to save some space and cost and fit the original specification's acceleration.

An outside concern would be that that's an unarmored design. That might be what you want, but bear in mind that it's very thin-skinned. A 1/3 system of armor per section goes a long way if the ship is supposed to be sturdy.

I forgot about half-sizes; knocking the NSW down a half space and adding that amount of armour balance each other out.

Also, most civilian designs don't really need a full-size control room.

Fair 'nuff.

You probably want to add a hangar for launching your robotic prospectors and smaller vehicles, and for general utility. As written the ship has no way to get anything much more than man-sized in or out without messily depressurizing a third of the ship. A hangar is essentially a giant cargo airlock.

Fair 'nuff, again.


Putting it all together, I seem to have 1 and 2/3 spaces currently unused... I suppose I should check the other books in the SS line to see if there's anything appropriate to fill them with. Maybe upgrade the armor to a full space, for a start.
