Olympus Corvettes.

Reading the ships info in SFOS it appears quite early in Earth Alliance's history, looking at the new box sets it isn't in the Early Years box set but the Third age. I haven't seen Armageddon yet, but am I right to think that this ship has been moved to the Third age era?

It's definitely in the Early EA fleet list, it appears they didn't feel the need to put it in the boxed set, probably in favour of other Skirmish ships. IIRC the only ship in all three sets is the Hyperion.

Olympus is in both Early Years and 3rd Age fleet lists.
The gunship variant is in the Early Years only.
