I have no concrete production plans yet. A fellow in the UK expressed interest in casting and selling the ships, but it's not set in stone yet. At the moment I don't have a budget yet or anything to do test prints, hopefully in the coming months. Around that time I could perhaps also consider my options regarding casting.
As for the ships themselves. In the meantime Ive slightly tweaked the bridges. I should try to start letting go of the Corvettes, they are practically done, so tweaking them more and more won't do that much (unless it's something mindblowing). The Frigate still need a bit of work on the detailing. The Destroyer has undergone some alterations (including a carrier variant), but will still need a bit of work until it's actually done.
After that it's finishing up the big transport ship, tweak its shape a bit and start adding details.
