According to my napkin math for CT ... @ 300 tons displacement, a TL=14 starship would require:
- J5 custom LBB5.80 drive = 18 tons
- 2G custom LBB5.80 drive = 15 tons
- PP5 custom LBB5.80 drive = 30 tons
- Fuel = 150+15 = 165 tons
- Fuel Purification Plant (200 tons capacity) = 4 tons
- Bridge = 20 tons
- Model/5 computer = 5 tons
18+15+30+165+4+20+5=257 tons
300 - 257 = 43 tons for crew staterooms (and everything else)
Crew
positions required:
- Pilot
- Navigator
- Engineer
- Engineer
- Medic
Get someone with Engineering-2 skill and you only need a crew of 4 (because Engineer/Engineer).
So call it 4 staterooms for crew ... which is 16 tons.
300 - (257+16) = 27 tons
If you arm the craft ... with 2 turrets and add a Gunnery-2 skilled member to the crew (so Gunner/Gunner who can operate both turrets with a single person) ... that will cost 6 tons for the fire control plus one stateroom.
At that point, you're down to 21 tons of payload capacity.
The starship can GO PLACES ... because J5/2G ... but there's not much it can "bring" to the places it "goes" to, because 21 tons isn't a lot of displacement to work with. However, it IS enough for a prospector (10 tons of cargo space for ore processing, minimum, as per CT Beltstrike, p3). It's also enough for 4 staterooms plus an air/raft for a team of specialists to go exploring with.
As a COURIER, such a starship would work QUITE WELL ... even if you're just talking 5 tons of
x-mail transport.
As a SURVEYOR, such a starship would do quite nicely for soaking up sensor data to store in "extensive data banks" for retrieval back at base.
But for an EXPLORER, where the point and purpose is to "get outside the starship" and start handling things up close and personal with special training and subject matter expert knowledge ... it's going to need to be outfitted with the specialized "stuff" needed for the exploratory expedition team in the 21 ton cargo hold.
