I was a big fan of the "Star Trek: Starfleet Command" games from the late 90s/early 00s and one of my favorite vessels was the Okinawa class frigate.
I did take some creative liberties with the design. On some points, because I just felt like it (Like the warp nacelles being tilted upwards instead of being flat behind the saucer). On other points, to make a plausible deck plan work with the rough silhouette of the Okinawa class which is intended to only have five decks and room for one or two shuttles. The 'Notes' and 'Specifications' section is head cannon as the "Starfleet Command" games weren't big on lore...
