The neo-standard thread- Standardising additional hull sizes.

[Suicide Junkie]

The starliners, it seems to me, fall under the more general Category of "civilian ship"

Perhaps "civilianship", "civiliantransport"?
troopheavyinfantry could be good as well.

It seems to me we have plenty of standard hull sizes already (16)
The items that stand out for me on Fyron's list are:
Transporthuge
cargo station (civilianstation, perhaps?)
The sat and mine sizes, leaving out the satmedium, as you suggested.
fighterbomber
weapplatformhuge

PS: I believe you missed the worldship in your list.
