Jump-6?

[The Thing]

Just out of idle curiousity, what ships in traveller use jump 6, if any?

I would assume the infamous "Express boat" network uses jump 6, but does anything else?

With a J6 capacity, 67% of the ship is taken up with the jump drive and fuel, so I'd imagine there's fairly little call for J6 ships as they can't carry cargo worth a damn, or troops, or anything but info.

Even J5 ships must devote 56% of their volume to jump drives, leaving little for cargo after the crew is crammed in.

One thing that the imperium could use AI for would be running high jump rated ships as we can assume a computer system would take up less room than a man and his life support, but apparently uncle cleon has his reasons for not letting AI to be developed, or maybe it was and something went horribly wrong...

So does anyone know if there are any J6 ships besides the xpress boat network and if so what do they do?

Actually, the xboats are only jump 4. There are reasons given about economy and the lack of jump 6 routes. Naval couriers are of course jump 6.

The TJ freighter is jump 6. Most warships are jump 4, jump 5 seems to mostly be cruisers such as the AHL. They can operate independently and don't need all of the destroyers, escorts and support to keep up.

Well, I learn something every day. CT uses 10% fuel per jump rating. MT, TNE and T4 [1] use 5 x drive volume. (10-35% instead of 10-60%) The 67 and 56 values become 42 and 36 in the newer systems.

EDIT: as robject corrected me, T4 uses 10% per parsec as well.

[1] Was this ever in the main book? I had to pull out Starships to find the 'following table.' EDIT: Found it in the errata. Bit embarrassing to leave out of the main book.

Reeeaallly? Hmmm, I remember T4s main book stating 10% per Jn. Did I misremember?

I had to look at the Starships book for T4. I couldn't find the jump drive table in the main book at all. Given the organization of T4, it doesn't surprise me. I found a table giving mass, price and so on for a given volume of drive, but not how much drive a given ship needs. I've found the errata
where they provide the jump drive sizes. Now I've read that, you are dead right, they went back to 10% per parsec. GT appears to be 10% as well. I've got no idea about T20.

Only the fastest couriers and deep-exploration scouts have jump-6 in the Terran Dominion. In the Imperium I can't think of any adventuring craft that pack a j-6.

Nah, you'd have to have a financier with deep pockets and not caring about investment return for an adventure craft to have that kind of range.

Or its a military scout craft. Or its stolen. (Or both )

The Fleet Courier in Supp. 9 is a jump-6 design.

There would be a market for jump-6 passenger liners between major worlds. If, that is, you're prepared to deep-six the ridiculous "all jumps cost the same regardless of range" notion. A jump-6 ticket that actually covered the true expenses would cost about 6 times as much per parsec as a jump-1 ticket (i.e. 36 times the cost of a jump-1 ticket).

I'm convinced that there are people who'd pay six times as much to get where they're going six times as fast (More than that, actually, since you'd skip the delays lost with intermediate stops).

Incidentally, IIRC the drop tank passenger liner service to Regina that was discontinued after the Thrimkhana Brilliance disaster was jump-6.

If the market is there for it, yeah, I think you are right. But a lot of it is dependent on the world at the other end of the J-6 jump. Is it a place worth going to and from? IIRC, the rules for passenger generation are based on the Trade classification types, so I am not completely convinced of that.

Also, there is the matter of the passage prices being pretty much flat. Meaning that there is no subsequent increase in price for a J-2 ticket, etc.

Of course, you can do anything you want IYTU.
