General Japanese Naval Forces Discussion HQ

as far as I know, the smokestacks are incorrect. What’s wrong with the turrets?

Ive seen both drawings and models of amagi with a floatplane and I don’t see anything really odd about the turrets it has

The turrets are the upgraded versions exclusive to the Nagato class rebuilds. You can easily identify them by the extra armor plate and larger rangefinders on the super firing turrets.

The catapult and floatplane did not exist when Amagi was designed, and the ship was cancelled before they could have been modified to carry them.

Its hard to tell, but this is… was turret #1 from Akagi, modified slightly to serve as the Kurosaki Battery at Ikishima. Two other turrets were taken from Tosa and moved to Busan and Tsushima.

Can anyone see if they can find better pictures than this? They should be good examples of how the turrets would’ve looked without the added armor if nothing else.

I guess I can at least understand why Gaijin did it. Finding proper references for the actual design of the turrets has been more challenging than I thought. Most people tend to just re-use the original 41cm turret design from Nagato, although they had been redesigned for Kaga, Amagi, and Kii.

Though the floatplane is just nonsense. Almost as if they wanted to save Nagato for a better occasion? Anniversary of New Power? Likely waiting until Nelson and Colorado are ready if anything.

Wait, are we seriously, finally getting the aiming system for naval rockets and mortars?!

Because I posted that very suggestion back in November 2023 :D

Very good website, thank you

Very nice. I don’t own anything detailed enough on the cancelled ships of the 8-8 fleet to have caught the smaller details. Its nice someone else has.

I’ll share some of the materials I’ve found.

45-caliber 40 cm Turret-mounted Cannon

Busan Fortress Jangjadeng Battery (Battleship Tosa No. 2 turret)

This 410 mm coastal gun is a turret from the Japanese Navy battleships Tosa, Kaga, and Akagi, which were canceled due to the Washington Naval Treaty. The Japanese Army repurposed these turrets as coastal defense guns for strait defense.

Heads up for any DMM players , after more than a year in-game (since August 9, 2023), the window for purchasing the battle trophy for naval katakana decals only has 53 days left . Each decal still costs 200GE.

Wish we had this stuff for the International servers. I’m quite jealous of the DMM servers cause they get all the fun stuff. Except for the funny accident where many including myself were lucky to get the A6M5 Ko DMM Camouflage, i still love it.

That’s very interesting! I’ve read the gun was used at the Busan battery, but haven’t been able to find any pictures of documents regarding it. I assume that much of the structure remains, even if the turret was scrapped?

I found a website somewhat related

Navy only?

DMM plans to eventually include ground as well. No news for air as of yet.

Hmm, it seems we got a response from Gaijin about the various inaccuracies Amagi has in the game. From what the developers are saying, they based the model on the 1919 drawings of the ship. The explanation still doesn’t account for the anachronistic catapult and incorrect turrets. Also, as a note, the 1919 drawings are part of the Amagi preliminaries, so in essence, this update gave us the very first completely paper ship design that’s ever actually been implemented in the game

Welp. Cats out of the bag now.

Where is this response?

Aye, or heck, No.13 when A-140 Prelims when, etc.

As a note, I’m not counting Krons as a purely paper ship, as Project 69 was at least laid down with the intention of being armed with 305mm guns and does represent the finalized design of the ship wait said weaponry.

Over on the Gaijin issue tracker,

Неправильно замоделен арт-директор IJN Amagi // Gaijin.net // Issues

Линейный крейсер IJN Amagi, не верно замоделен мостик // Gaijin.net // Issues

The exact response as translated is:
“In the game, the ship is made according to the drawing of 1919. It is not a mistake.”

Also pardon the double post, your response didn’t pop up until I hit send
