I hope you're well with Dirk there, but anyway lets pass to the business.
To be straight - the question of copying Hyperion warship is not on tasks, no matter what. It was given to us by Elizabeth some time ago by her good will, and if to be honest I don't think she would be appreciate it. You already said the other reasons, but there are technical problems, such as unique Nomad power cell and it's energy system is still being tested.
Anyway, I even don't think even our gaul freinds would love to fight against some warship which known "the one" under Phoenix command, it will raise some questions from them, which will bring us in problematic situation in Tau, Gallic region.
Moreover, I can't find since when Zoners are dealing with people by firepower? Or it's new kind of TAZ diplomacy? It's their fault to get an enemy with such great fleet. Zoners don't fight with the houses, prior. If they won't deal with them in peaceful way, the Hyperion copy won't save them. Even our homeship's fleet with Vega and Hyperion won't even have a chance to win a fight against war machine known as Gallia.
But... Quiron, you should remember the Nephilim warship, which we're produced to the Order, currently known as CV-Inquisitor. I think we still have blueprints and even could start an construction.
That's all for now. Tell me if you will need Phoenix homeship take you back home.
