These are FASA Drawings of unknown Ships.
This section is primarily for the fun of cataloging the various unknown
fasa drawings of ships that where used in the backview of many of the illustrations over
the years of fasa's trek publication.
Considering where most of the images came from(usually above a planetoid and/or near military starbases), They where not intended to represent playable ships, rather they are there to show activity in the drawings.
Lee and I suggest that most of those ships are probably commercial designs for the private sector, workyards, transport etc... some of the ships maybe used by the governing planet/military for sub-contract use, such as the "LiL Tyke" Tug pictured below. Check out Morena Shipyards for downloadable photos of these ships.

"David Tepool and Jordan Weisman sketched out some of the roughs on
the ships originally. Others were done by FASA artists and adapted by
David when he did the Ship Construction Manual. It's possible one of
those slipped into the cover that was never actually intended for
use. It isn't likely to be Gorn, as we were never working on those. It
may have been a Federation colony ship design -- but most of the
Federation ships used outboard nacelles. The design looks vaguely
Klingon to me, somehow..."-Guy McLimore
