Considering the Tyr was the ship which got me thinking along these lines, the similarity perhaps isn't surprising. But looking back in comparison... it's a much closer knockoff than I actually intended it to be. *Wince.* My apologies if I got her too close to the original inspiration...

Still, the Tyr didn't match what I wanted (too little armor on the barbettes, too little TDS, stability way too low for my preferences), so I wanted to design my own. I highly doubt I'll get around to building anything this big, though.
