[Spaceship] Query: Traveller Jump Sled Performance
I'm designing a Traveller style J-2 Jump Sled to deliver a payload to an empty parsec using RPK's " GURPS Spaceships In Traveller" rules. The payload is a large Modular Section taking up the first 2 hull sections with everything else in the rear hull section. The J-2 Jump Drive requires 3 fuel tanks with the payload attached. Without the payload module would it only need 1 full tank for the return trip? (This fuel would have to be carried in the payload module since there is no room for it in the drive section.) Note that the following design can be scaled down for a smaller payload.
