Joan’s Fighting Spacecraft
Joan's Fighting Spacecraft was a publication that provided information, schematics, and specifications for almost any ship in space, including civilian, Terran Confederation, and Kilrathi ships.

Supplements have been found in numerous publications including Claw Marks and Star*Soldier magazines. The publisher of Joan's Fighting Spacecraft was Ivan Borger in the year 2669.
Alternate History (The real world)
Joan's Fighting Spacecraft has appeared in multiple Wing Commander game manuals. These include Wing Commander, Wing Commander II: Vengeance of the Kilrathi, The Kilrathi Saga, and Wing Commander Arena. Apparently, the name seems to be based on real-life Jane's Information Group.
