Well that puts McEvedy's Folly in new light.
How so? Admittedly, the ship would have been in MoC for a year or so back in the 2760s, but I doubt it would give them much of a leg up on other Star League ships.
So, we have three right now:
MCS Danai Centrella
MCS Tuatha de Danann
MCS Emerald Queen
Any idea why there is a reference of Irish mythology in the naming of our new warships?
Well, we have 3 ship names. I did a sort of long winded post about 2 days ago explaining why I think there are more than just those three (Basically the production rate for there to be only those 3 is ludicrously slow, and the named ships were the first off the line in the alternating pattern, not the only ones off the line).
The naming thing...I'm not sure. There doesn't seem to be a pattern so far.
Danai Centrella makes sense.
Tuatha de Danaan? There is a small Morrigan (Irish Goddess of War and Death) sect in the Trznadel Cluster, so I suppose they could've gotten the name from there, but its definitely an odd choice. Wiki suggests one of the translations for the name could be "People of the Goddess Danu," which could fit for the Magistracy, but it still seems to be an odd choice.
Emerald Queen is similarly odd. It has MoC connections, and we assume its linked to the anime, but it could also just reference to the green on the MoC flag. Or it could be a reference to the Cleopatra Emerald mine in Egypt.
It seems the best rule of thumb for the naming of ships might be "Something feminine" I suppose.
