Based on a drawing from the now apparently defunct HMS Andrew site, basically my idea of what the Hood would have looked like if she had survived to be refitted like Renown.
Also based on a drawing from HMS Andrew, A British "super battleship" basically an upgunned KGV or Lion
Not the best quality, basically a "kitbash" of a Yamato schematic I found on the web.
http://www.german-navy.de/marine.htm has schematics for almost every major German warship from WW1 through WW2, plus some never completed Z-plan ships.
http://hmsprinceofwales.freeservers.com/ has drawings of the Prince of Wales
http://idd007xs.eresmas.net/bismarck.html has some good color drawings of the Bismarck
Hope these are a start, it might be a bit before I can do some new drawings, I've got some stuff I've got to be doing for a job, so I'm not going to have much in the way of free time, but I'll see what I can do. If you want the basis for some Space Battleship Yamato style conversions, I've also got several ship drawings I've scanned out of some books or gotten off websites, not very clean looking, but a pretty wide selection to use as a start.
