See what I did there? Rogue Trader stats for the PC ship from Ark of Lost Souls.
Some stuff is debatable, that's why I dubbed it v1, feel free to comment.
I am more or less at ease with stats as they are. One point is that the AC is Gladius-based, which in turn is based on the Sword frigate. The Sword can't mount lance weapons, yet the fluff text about the AC speaks both of lance batteries and that changes to the Gladius pattern are more or less internal. A bit hard to reconcile. I decided to give the AC lance batteries with improved, more efficient stats. For an escort vessel it is quite deadly but it's focus isn't on combat as you will undoubtedly realize.
Also I wasn't sure on including a teleportarium. Maybe something for the PCs to acquire during play, if they want to have it.
Another issue would rating the crew, I went with veteran (50) - again to leave room for improvement.
