Urgh, I hope the starship sheets don’t need modification. I just spent the last three months cleaning up (and creating) more than 140 Corey Belote-style starship sheets and compiling and pre-statting them in my GoogleDocs here.
Current tally (organized by class alphabetically):
82 Federation starship PDFs
19 Federation shuttle PDFs
22 Klingon starship PDFs
1 Ferengi starship PDF (it’s the D’Kora-class raider, natch)
17 Romulan starship PDFs
Disclaimer: I didn’t create most of these PDFs; Corey Belote of Continuing Mission did. I just took up where he left off since he’s been out of contact for a while. See here for more details.
