@Tigerman77:
I’m not arguing about how to use the pieces! I’m arguing the fact that if made available there could be house rules made to fit the units in the game….global or tactical game…any game! IMHO, I think the 3 naval units I mentioned before could add to a game, obviously not as historic as adding the mechs and tacs!! Since we have 2 people willing to make pieces I think it would be good to expand unit catagories as much as possible. Just sayin!
Well, I do agree on this much… I think that perhaps that, for example, an Alaska, which really is roughly a half-step between, say, and Iowa and a Baltimore-class cruiser, would be a great 7-7 unit on a d12 system.  As to whether it gets 1 hit or 2, I’m thinking that whatever a carrier gets, it would be about the same: not as tough as a battleship, but definitely a step above a cruiser, and probably closer to a BB than to a CA.  Probably this means that if you go to a 3-hit BB, or a 1 hit CV, the armor difference between a BB and a BC could be represented, but if both the CV and the BB stay 2-hit units, then a BC would be there too.
Fast Battleships really ended the value of the BC. They got the same speed and also had larger guns and better plating.
Yeah, that’s basically the size of it.
But the battlecruiser also had a more efficient range that it could operate making them suited for commerce raiding and patrolling. Battleships sucked fuel and needed close bases to operate from.
The Battlecuiser should have the increased range which translates into ‘speed’
Well, that’s a point.  What we’re really dealing with here is actually “strategic” speed rather than “tactical” speed, given the game’s overall scale, which is why we probably can’t represent the difference between fast tanks and slow ones on this scale.  In efficiency, though, I’m not sure that this works so well as a differentiator between BB’s and BC’s.  I think it actually probably works better on an “old” vs. “new” basis.  For example, I was just reading up on the battle of Guadalcanal the other month (awesome book btw, titled Neptune’s Inferno any of y’all who are really interested in getting into the nuts and bolts of the Pacific War, that guy’s an awesome writer, I couldn’t put it down…) but anyway, the author answered a Q I’d long had: “Why didn’t the US use some of its old BB’s in the Guadalcanal Campaign?”  The answer seems to be this very effciency issue you raised: the US didn’t yet have the oiler fleet to keep the old BB’s supplied that far from base.
Interestingly, though, the new BB’s just coming on line were much more efficient, which is why the Washington and SD were on-hand to finally be sent into the fray in the decisive 2nd Naval Battle of Guadalcanal!
Given this, I’d say it makes more sense to give the movement range of 3 to all the new BB’s, BC’s, CV’s/ CVL’s, CA’s/CL’s & DD’s, but not to the old BB’s subs, transports, DE’s, and CVE’s (if we have them).
