Re: GURPS 3E to 4E Traveller
Jump drives are easy: 1 space per 100 dtons, plus 1 x jump number spaces per 100 dtons. Fuel requirement is 10% of hull size per jump number. The only question is where to put the TL breaks; my inclination is to say that anything up to at least TTL 15 is G(4)TL 11.

Re: GURPS 3E to 4E Traveller
Coming back to this:
For tech levels I use: Code:
Trav TL GURPS TL 0 0 1 1 1 2 1 3 2 4 3 5 4 6 5 6 6 7 7 7 8 8 9 9 10 (A) 9 11 (B) 9 12 (C) 10 13 (D) 10 14 (E) 11 15 (F) 11 16 (G) 11 17+ 12 The fuel requirement is jump distance in systems. This might seem low, but Spaceships assumes a lot of systems are eaten up in stuff that takes up little space in a CT ship, so it works out fairly well. As you'd expect from the above TL table, TL9 limits you to J1-2, TL10 to J3-4, and TL11 allows J5-6. As a matter of campaign feel, I use the electro-mechanical computer option, which means that TL10 computers are only about as capable as ours today. As a rule of thumb, the mass of a ship for Spaceships can be taken from" Traveller Displacement Tons x 4 to 4.5, round to nearest standard SM/mass. Round in whichever direction seems to make the most sense. Most small craft are 100 tons, a Shuttle or a Type-S scout is 300 tons, 200-300 ton traders are 1000 tons, a 400 ton subbie or a 600t ton liner are 3000 tons, as is a Broadsword. It's pretty coarse, but it's been working for me.

Re: GURPS 3E to 4E Traveller
I've seen one of the writers/editors (Kromm?) has a "My GURPS" page on Traveller. Spaceship elements, racial templates, etc.

Re: GURPS 3E to 4E Traveller
The reason I didn't follow Interstellar Wars' tech level progression is that it comes up against the effect TL12 limit of UT and Spaceships way too soon, so I'd be having to make up a big list of TL12, TL11^, and TL12^ items and what Traveller TL they corresponded to. As that would work in direct opposition to my main reason to just use 4e and UT, etc. (laziness), I ruled it out early on.
My scale cuts down on the tech that's not available enough that I can rule Yes/No on a case by case basis as it comes up (especially as TL11 items tend to be found items, as I'm running a New Era game). It also leaves me with all of TL12 for ancients' tech if I want it.
