The Federation's Akula class destroyer. As far as I'm aware, the ship's only appearances were in the "Star Trek: Starfleet Command" and "ST: Klingon Academy" games. In my diagram, I decided to refer to the vessel as a "picket cruiser" since the term "destroyer" felt a little out of whack for the nomenclature of a nominally peaceful organization.
I took some creative liberties with the design as late-90s era graphics weren't known for being high def. I also absolutely hated the "thin slab" secondary hull that the original design featured. So I gave it a more voluminous secondary hull which looks like it could actually accommodate some equipment and infrastructure. The 'Notes' and 'Specifications' sections is head cannon since the "Starfleet Command" games weren't big on lore...
