I got a nice surprise in my mailbox this afternoon! Spent the evening reading through it. The design system exceeded my expectations: it seems to strike a very nice balance between ease of use & offering a wide array of options. Tomorrow I'm going to try making up some vehicles for it.
I'd rate it as a VAST improvement over the old vehicle supplements. For one, it's actually useable, and I think it will come in handy to create vehicles for other game systems as well.
It's nice that there's some new-to-Traveller material in there: such as Aerodynes, vacustat airships, and super-cavitation drive submersibles to name a few.
The book also had some nice surprises: such as the stats for OTU alien vehicles, as well as vehicles from Judge Dredd, Strontium Dog, & Hammer's Slammers books.
I'd also completely forgotten that the book included power armor construction rules, so that was a nice "surprise" as well.
