The Jump Drive is the technology in Traveller that allows for FTL travel. We play
Traveller, We know this. But have you thought about what that means?
The Jump
Drive moves the PCs from hex to hex, yes. But how? You look at the jump rating, which is a
cross-reference of the size of the ship and the letter code, A to Z, of the
drive. These give us the ratings from 1 to 6. Still telling you things you
already know.
The point is
this: a jump drive is not rated by how fast it can go. Any jump “takes about
one week” (TTB, p. 49) whether you have a tiny type-A in your Free Trader or a
mammoth type-Z in your super-cargo freighter.
A jump drive
rating tells you how far it can go in that one week. A jump-2 drive is not
twice as fast as a jump-1 drive;
it has twice the range of the jump-1 drive.
There is no
real-world comparison for this distinction. We rate vehicles, from bicycles to
Blackbirds in rate of distance per unit of time. Faster vehicles cover the
distance in less time. Not so in Traveller. A jump-1 drive takes as long as a
jump-6 drive to do a one-hex transit. End of story.
The difference
is of vital importance to Travellers. Why? Because of a hard-wired fact of the
Traveller setting, whether the 3rd Imperium or my own Church and
Empire setting. Information, in order to propagate, must be carried. In ships,
that all take a week to jump.
From Supp 8, Library Data: Another central fact of interstellar travel is that no method of
information transfer faster than jump drive transmission has been discovered.
Ships can carry messages, but radio still lags at mere light speed.
Communication is always restricted to the speed of interstellar
transportation.
The distances
between worlds is a fixed and unchanging quantity. If you want information
about a world 6 hexes away, how long will it take for that information to reach
you? Answer: either six weeks, or one. If you get your
information delivered express, you get to act a month and a half before
the other guy does, who’s waiting on a jump-1 courier to bring it.
The same goes
when Travellers decide to, well, travel. A ship with Jump-4 can get a Traveller
from Holtzmann to Stavanger in one week. A Jump-2 ship will take 3 weeks to
make the same trip. Look at the map to figure out why. If your PC and his
competition have a goal to reach on Stavanger, what is the essential play? Securing the ship with long enough legs to
get you there in one week.
Add to that this
complication. Not all planets have the same access to the information delivery network.
TTB page 89 says:
Within the subsector, local governments
will have established communications or trade routes connecting some (but not
all) worlds.
AND
Communications routes should be
carefully drawn so as to avoid making all parts of the subsector accessible; a subsector
should reserve some areas as backwaters for exploration and adventure.
Depending on where you are, it may
take even longer for the Big News to reach you.
The Traveller who wants to do big
things and make a name for himself needs information, and needs it faster than
his competition. Knowledge is Power. The Jump drive is the key to that power.
