Possible Japanese Navy Ships

[Delta Force]

Redid my Armored Cruiser (Large)

I think my 9,600 ton armored cruisers better represent the future of the type than the Tsukuba. The Tsukuba is far too large for an armored cruiser and has a greater tonnage than most battleships. 23 knots gives you a speed advantage over most ships, but no one else is going that fast anyways and it is too early to take full advantage of its positioning edge. For the same price as a Tsukuba a conventional battleship and a large percentage of an armored cruiser can be purchased.

Which is why if it gets built at all its getting built as a one-off class.  I do feel sorry for any PC or AC that gets in its path.

Admitedly we are allied, but honestly it only has 2 knots on the REs which are full up battleships (if insanely fast for the period)

I don't see any 9600t ACs in your ency, therefor they don't exist right now. Might want to fix that. :)

So then the Tsukuba can scout for your battleline  ;)

Got a little crazed posting new Kongos, eh?  :)

I'm a little dubious about trying to fit the extra 12" turret on a hull that's only 5' longer than the preceeding Asahi class, that seems more than a little bit tight.  I'm also puzzled by the secondary layout.  The barbette armor is perhaps a bit light, though the rest of the armor suite is very good.  Reserve weight seems excessive.

Oh definitely!  The second run around is the Bureau of Design's opportunity to experiment with triple turrets on a ship that is basically the same so they can better gauge the effectiveness of each layout.

Now that you point out the length thing  didn't notice that, it only really matters for the Kongo 2s, which have the third turret (and also don't have the 4 twin 8" turrets).  the twin 8" turrets are on the sides in a more central location. 
Secondaries I switched over to casemates like they were originally supposed to be (I always forget to check that).

I should have been clearer: what I find puzzling about the secondary battery is the 6 guns on the main deck and 10 guns elevated.  That leaves me scratching my head, as I can't see a reason for that other than the IJN is using superstructures that look like inverted pagodas.  :)

[Darman]

Oh.  Visualizing the side of the ship with the twin 8" turrets i didn't think there was room on the deck level for more than 3 6" guns on each side. 

[Darman]

Out of curiousity is there anything else that might be an issue?  Cuz those are supposed to be the final designs.  I just want to check and be sure..

8" guns aren't correctly mounted: it's showing 1 single turret for 2 guns.

Slopes of the protected deck (which might get hit directly by an enemy shell) are probably too light at only 1".
