[KWorld]

Huge, lacks both a radio and torpedo tubes.  Deck armor very weak over the stern, very heavy over the central part of the ship.

Other than those comments, looks OK if you're going down the road of huge BBs.

[Darman]

I strongly suspect that most of us will be going down that road

Certainly possible.  If both the RN and RMI go down this road, it will be hard from France to resist going as well.   If France goes, well, can Germany, Russia, the US, and Japan resist going?  It would be difficult.

[Darman]

If both the RN and the RMI go down that road can their ally Japan afford to not build at least a couple ships that can contribute to the joint allied fleet?

What Italy does I doubt matters too much to the IJN.  If the RN, on the other hand, standardizes on monster BBs and starts deploying them to the Far East, well, then the IJN would probably have to match them.

Yea, the RN is always of more concern.  Of equal concern would be the presence in the Russian fleet of such monsters.  Even if they weren't assigned to the Pacific Fleet

Yeah, if the "rot" spreads beyond the RN, it may be hard for others to not follow suit.  The USN can use the Incomparables in discussions with the US Congress without having to have similar ships of it's own, but if the MN and the IJN start building BBs of similar size, that changes the equation.  [I hadn't expected ships to be that large for most of a decade, with the second generation of DNs, personally.]

[Tanthalas]

Neither had I, but with a couple nations already building or having proposed ships that large or close to that large, I felt I needed to come up with somthing comperable instead of building more 13.5K (which I felt were bloody huge for the period) ships.

[Darman]

You could always decide against building larger BBs and go with the Jeune Ecole instead...

[KWorld]

Jeune Ecole probably doesn't make as much sense for an ally of the UKs.

Agreed but if its a choice of many smaller ships versus really large and expensive battleships... some might choose the less expensive route

Please tell me you cheated on the report. I can't believe you can actually put all that on that ship.


P.S.:
Using French is a bit unfair, it was almost certain Jef would catch that immediately
