A fresh New Year celebration, the return of the Dockyard, and other new features in the coming update! Read it on the portal
There are two ships available in the Dockyard which are free to obtain. Tier 3 Dreadnaught is fairly early, and the newly introduced Repulse is halfway through.
If you buy a stage, you get the standard rewards for that stage. So the ships would be purchased as you would expect.
Once you've unlocked stages buy purchase, you can still grind and obtain the "stage unlocks" through in-game missions. For every Stage Unlock you get that works on a stage you've already been rewarded for, you get 250 Steel instead of getting nothing (as you've already gotten the stuff earlier)
