If you're a follower on my Patreon, you'll get to see the preview of the Squadron Strike: Traveller SSD book. This is what's in it - and this one covers two ships that are a decent match to each other:
A class history (new to Traveller and Official Traveller Canon) with a gorgeous image of the ship.
A 3D SSD for the base variant, a 2D version of the base variant, and a 3D variant to add more variety to your scenarios.
