Concerns about excessive topweight. She and Maya never got the the extensive rebuild that Takao & Atago received because of timing. The escalating war situation and busy yards made it impossible to schedule the rebuilds. So, she never got the additional bulges and reduced superstructure that would have accommodated the new armament. That's also why she never received quad TT mounts and reloads.



From what i saw on the underwater footage the easiest upgrade was the addition of single 25 mm MG all over her decks. Hard to believe they didn't replace the doubles for triples.. Thanks Dan!

These guns are sitting in plain sight there is no shield housing whatsoever i found this most interesting.


I think it likely that those shields were torn away on the way to the bottom.




Dan any idea why the navy never upgraded the ship with the new Type 89?

If that's the case i think that bridge looks wonderful after those 2 hits and decades underwater!

[quote="Dan K"]As I believe you're aware, Jose, topweight became a big concern after the 4th Fleet incidents. The Mogami class original design had a much larger bridge structure - see below.

I remember seeing that drawing on my Mogami class Kajinsha book but given my Japanese is awful i never really understood what was being explained here. I thought it was the opposite as a matter of fact, i thought the navy wanted to make their main bridge structures bigger. I remember reading about the nasty typhoon years ago but i honestly forgot. Thanks for the history lesson though :thumbs_up_1: :thumbs_up_1: BTW, i was watching Chokai's underwater video and Petrel snatched some great shots of the single HA 45 cal guns. These guns are sitting in plain sight there is no shield housing whatsoever i found this most interesting.

Btw, for those that were waiting, Fujimi is releasing the other 1/700 sisters. Looks promising:

Kumano 1944 - https://www.1999.co.jp/eng/10628812

Suzuya 1944 - https://www.1999.co.jp/eng/10628810

MIkuma 1942 - https://www.1999.co.jp/eng/10635011

Mogami 1942 - https://www.1999.co.jp/eng/10635006

Thanks for the heads up Dan :thumbs_up_1: It was great to see the ship sitting up right. Bridge structure got beat up pretty bad but i could still make out the wind baffles layout. These were very puny structures compared to the Takao's.

The RV Petrel has found the Mogami in about 4700 plus feet of water! She looks to be fully intact, only missing the tip of the bow section. Another incredible find by Petrel!! :thumbs_up_1: :thumbs_up_1:

You are correct, Dick. The caption on the lower right clearly says Tone (利根); just never looked closely enough, I guess.

However, for the purposes of the particular discussion, Mogami and Mikuma had a more pronounced expansion of their width as the hull rose to the main deck, with something of a knuckle.

Cross-section - Mogami top, Suzuya bottom, both as refit on right.jpg

Dan, I have a question on the caption for the cross sections you posted above. Obviously, the top is Mogami, pre-refit on the left and post-refit on the right. However, to me it looks like the bottom cross sections are post-refit Suzuya on the left and Tone on the right. Both the top right and bottom left drawings flag the strengthening added in the refit. Tone on the right was built stronger and therefore the drawing doesn't reference the stiffening strakes.

Well, a conversion is possible, though there are differences that need to be taken into consideration. The upper hull and 01 High Angle Gun Deck are different, as are the arrangements at the base of the superstructure. Some of these references have been posted previously, but these should be a little larger.


:worship_1:

Thanks Dan , very useful and informative , the conversion looks a bit demanding ,but as You said ,possible .Looks like a good project anyway.

Yes VeryFire 1/350 IJN Aoba was announced a couple of months ago,when they will release it? ,nobody knows .
And not an expert, but to convert the 1/350 Mogami into her sisters ,I don't think will be very hard,maybe our IJN sensei Dan Kaplan can comment on this.

well hopefully they will come out with a 1/350 scale of these!!



IMO no need for those ,Tamiya's full gun Mogami is quite new ,about 8 years only and is gorgeous ,more needed is a Kako Class since Veryfire will make the Aoba, also I will kill for a Torpedo Cruiser ,Kitakami or Oi,that would be awesome.
