Starsector 0.97a is out! (02/02/24); New blog post: Anubis-class Cruiser (12/20/24)
I think the mora was less a militaric vessel and more a private/exploration one. I think the XIV battlegroup didnt have it as main carrier.
The lore suggests it was used heavily, though, which is the root of the question. Taken right from the in-game lore on the ship page:Armored to withstand the fury of battle alongside the Onslaught,That sounds like a pretty main combat vessel.
...So why are these in the field? The Domain navy decommissioned them from military service, so they were de-militarized and sold to budget-minded civilian enterprises in development on the Domain’s frontier, as having some former carriers with big handling/construction bays can be a very useful thing. Once the Collapse comes around, these former construction/mine drone handlers slash ersatz mobile drydocks are re-militarized (thus less useful out-of-combat stats than one might expect). Used perhaps more by pirates, independents, and the Luddic Church more than by the Hegemony or TriTachyon, so that the big carrier fleets of these guys can be supported by something better than Condors but not so good as the Heron or Gemini....
