VHB 2026 Errata

I'm seeing Grav vehicles at TL8 but according to the Core Rules (and the TL chart in T5), gravitics are introduced at TL9?

World Builder's Handbook has early grav vehicles like air/raft at TL8, as it should be in Traveller.

I personally think TL9 would be better for the "Early" Grav, and TL8 for "Prototype", but that is just me. That would make TL10 the "Standard" against which everything else is compared.

(That would also fit with the Megatraveller TL9/10/12 Basic/Standard/High-Efficiency Grav-module breakdown).

Both T5 and the Mongoose core rulebook put grav vehicles with gravitics at TL9. If an air/raft shows up at TL8, that’s not early grav, that’s just ignoring the tech tree.

In original Classic Traveller, Air/Rafts were TL8.

(But then again, in CT, TL8 corresponded to the years 1980-1989 also). - Where's my flying car!

But I gave my personal opinion in my previous post.

Air/Rafts have always been TL8.
I think it was MegaTraveller that introduced the concept of Lifters as a TL8 grav tech that was very limited, hence the 10D limit to grav vehicle range.

Yes. The MT Interplanetary G-Drive had a 10D limit, and was TL10. The M-Drive "Thruster Plate" was TL11 and not limited by gravity wells.

The Vehicle Handbook Update 2026 confirms that Mongoose grav drives function out to 10D. It just takes a while.

It is a thing in T5 as well.
