I'm hurt, Rich. Really hurt.
LOL, Rocky!! Remember though, I'm just kibitzin'. Though I am familiar with Urumi, because of, uh, other posts....
I was unaware of the house rule; that does change the economics considerably. But what if she were converted to an oiler, then the oiler converted to a carrier, post-treaty?
:-})
Seriously, given the house rule, I'll say keep her as a BB. Wes has a good suggestion with the moderate rebuild, though I'd suggest an aviation component be added for long-range gunnery spotting and scouting. She could occupy a 'Malaya' or 'Barham' role in your fleet. While it's nice to have all first line BB's, as the USN showed in the historical Pacific, having BB's available for second line duties can be clearly in the 'good thing' category too.
All in all, a pretty good discussion, RD! Thanks for opening your decision for public debate...
Regards,
Big Rich
