Jump drive size reduction due to tech increase

[Vormaerin]

I don't think this is a thing in MgT2e, but in other editions the prototype jump drives didn't have Jump Regulators. So a J2 drive didn't jump 1 OR 2. They Jumped 2. Not 0. Not 1. Just 2. Every time.

So that could be a fun thing to put on a TL 10 J2 as a disadvantage

That's not quite how it worked in CT. You COULD make shorter jumps, but without a jump governor (introduced in High Guard) you always used the fuel for the full drive rating.

It's mentioned as still being a thing in Starship Operator's Manual, but mostly in the context of something that might break... and working as you say (which is also how T5 does it), with the ship having to aim at a 100D jump shadow (the star's one would be simplest and less prone to overshot) in order to make the shorter jump. But still using all the fuel.

As far as any prototech, yep. I agree that it's too early for their Jump Governors to have been developed. Good limiter.

Yeah, CT initially had a rule that you always used the full fuel regardless of the length of the jump, but they changed that pretty quickly. The version of Jump Governor I'm referring to is used in T5. I'd have to look back to see if it's mentioned in other editions.

It is an actual item with a cost and a displacement tonnage in HG79. When the rules were revised for HG80 and CT 81 it was never mentioned, but drives now use fuel as if they have a jump governor.

And, of course, in GDW's Traveller-derivative boardgame Dark Nebula the Terran and Aslan starships are initially limited to only jumping along marked jump routes (as they are in the boardgame Imperium), but a "tech advance" achieved during the game allows them to jump in any direction and to ignore the 'railroad tracks' between the star systems.
