CNS Atlantis (By now, only her and the similar CNS Olympus remain out of the class of 5 vessels). Complete overhaul, as with the battleships and battlecruisers remaining from WWI. 5.5" and 3" HA guns replaced by 5 twin 4"/45s, 3 twin 40mm Bofors and 8 single (original) 20mm Oerlikons. Torpedoes repositioned and added, new bow, new funnels, and new bridge to fir staff for operating a destroyer squadron.
As of now though, I need help with the radars, comms antennas, etc. Those have never been my forte. British and American designs would help. Once I learn more about them, I'll end up designing my own AU versions. Rigging will be worked out as soon as the radars and stuff that belong on the mast are put in. As of now too, these are in the works...

A number of them are just conversions done of the same class of ship during and up to their entry into WWII. I am also thinking of transferring some to my other AU nations that are in the works.
