The Thirteenth Pursuit Group was a Federation Starfleet pursuit group based at Starbase 14. (FASA RPG: Federation Ship Recognition Manual)
Like many pursuit groups of the late 23rd century, the Thirteenth Pursuit Group was comprised of 12 Scorpio-class corvettes in three flights of four ships each.
- In the FASA continuity, pursuit groups seem to be a counterpart to perimeter action groups in other continuities.
