From Introduction:
No foray into a Star Wars setting is complete without ships. The previous version of this book included the bare minimum, with a series of disjointed rules that I wrote three years ago and layer a thin veneer of polish over. Since it's first release last summer, this book has undergone a significant overhaul to make it more appealing and engaging with players and DMs.
While I've ultimately spent more time on the core content of the Player Handbook and the Expanded Content, this book has been significantly more difficult. Within the context of 5e, what I, and my group, have written here has been uncharted territory. I hope it makes sense.
This book is designed to parallel the 5e Player's Handbook as much as it can. It includes all the relevant chapters, as they relate to the space component of the game.
