Here's what the section header says:
The ships presented in this chapter are the same as those featured in the Traveller Core Rulebook. However, here you have the full benefit of the High Guard ship construction system, along with the necessary data
sheets that not only show you exactly how all the common spacecraft were constructed, but also provide you with the ability to dive in and made your own changes and modifications. This will allow you to create
countless variations for specialised missions, filling space with what should indeed be common spacecraft.
So you have the same low-res-ish 3D images along with deckplans and some alternate graphics of the ships. Nothing to write home about. There's some new ones in there (Express Boat, Deployment Shuttle, some more of the designs you have seen in the past).
Then it starts getting into warships. A 50k armored cruiser, a DE, an escort, and a 200ton SDB. There are some errors on the ship descriptions (like the SDB has 33 tons of mystery armor because there's no specs for it), and the DE has a descriptionless Thrust-9 drive, too.
Really the core book ship info belonged in the core book. They could have removed the 3D imagery and put these in there place.
If you were hoping for new designs, you get a couple, not sure if the 50k cruiser has appeared before or not. It's CA (or Armored Cruiser, but also known as a Heavy Cruiser)
