The next step in the development of the second batch of the 30FFM Mogami Class.

Ten New FFMs will be built, with the overall construction costs to be disclosed in the soon-to-be released FY2024 budget. These new frigates/destroyers will be of an improved and enlarged design. While the Mogami-class has a standard displacement of 3,900 tons, a length of 133 meters and a beam of 16.3 meters, the “New FFM/30FFM NG/ 30FFM Batch 2” has a standard displacement of 4,880 tons, an overall length of 142 meters, and beam of 17 meters.

I'm surprised that the engine configuration is the same even though the displacement is increased by almost 1000 tons... glory to MT30.

The number and size of the funnels do not seem to have changed, so if they have changed, it would be diesel with approximately the same power output.

Mogami class frigate 3,900 tons standard 70,000 ps over 30 knots

JDS Tachikaze (DDG-168) 3,850 tons standard 60,000 ps 32 knots

JS Haruna (DDH-141) 4,950 tons standard 70,000 ps 31 knots

Maya class destroyer 8,200 tons standard 69,000 ps 30 knots

FFM second batch 4,880 tons standard 70,000 ps over 30 knots

Some new reporting on the JMSDF BMD ship.
Similar footprint to the Zumwalt-class, though roughly 20-25% less displacement. (a similarity the author's seem to have not noticed)
Of course we'll have to wait and see. The scale of the ship has already changed and reduced a couple times.
Additional reporting on various JMSDF projects.

Since there's no Imperial Japan Navy thread, I'll put AKAGI first look on this thread:



The video link also from the article. 18,000 Feet in ocean floor also one of the reason it is not easy to find. JMSDF was and is continue recycle Imperial Japan Navy vessels name. However personally I do hope they're recycling Shokaku and Zuilaku name rather then Akagi. Akagi maybe the flagship, however Shokaku and Zuikaku is undoubtebly the best IJN carriers.

This channel provide quite good graphics on IJN Carriers, Battleships and other major vessels. However mostly in Japanese and also in Japanese Kanji. Still this one, the channel provide also in latin alphabets.

Quite good description on IJN major vessels. This one on the four IJN carriers that's involve in Midway. Akagi, Kaga, Hiryu and Soryu. Just realized even they are sister ships, Hiryu and Soryu have different placement sides on bridges. Despite some talk that Akagi and Kaga was sister ships, actually they ware not. Akagi sister ship was Amagi, that's destroy in shipyard during Kanto earth quake.

Add:

This video talk about evolution of IJN carriers design. It's in Japanese and all Kanji. However the video graphics can shown the evolution pattern. However it's until Hiryu and Sorry. So it is not touching Shokaku-Zuikaku, or later on to Urnyu and Taiho design late in the War.

The channel just put video graphics on Shinano. The third Yamato class Battleships that being converted to Aircraft Carrier. This video shown how Shinano should be if already fully operational with all systems and armaments available. When US submarine sunk her, it is been talk from Japanese documents, that she's not fully operational yet, and some damage controll systems has not fully operational or even installed yet.

This channel shown graphics on Taiho. Put it here, as this video shown what basically culmination of IJN purpose build carrier design. From Hiryu and Soryu (on previous video), to Shokaku-Zuikaku, then Unryu and culminate with Taiho. There's comparison between Taiho with Shokaku design.

Kind of ironic that latter design of IJN carriers shown better protection from aerial attack, but both Taiho even Shinano, all sunk by submarines. Video shown also new carrier fighters that supposedly bring IJN airwing on par with US newer fighters and bombers.

Couple picture from online sites (diplomat.com) on Izumo (before and after conversion).

More then six decades apart, at least from my Amateur eyes, there's base design similarities derived from Taiho. Off course US influence is there. They have similarities on dimension after all.

Last month the Japanese Ministry of Defense (MOD) announced that it has signed four contracts with Mitsubishi Heavy Industries (MHI) to quickly develop and produce various standoff (long-range) missiles. These are four quite important programs.



And here a nice video on board the Kumano FFM-2, the second 30FFM Mogami Class frigate.

Another video of the Kumano with the CIC in pretty nice view.

Thank you for sharing.
The 30FFM Mogami class vessels are really good looking and highly advanced....



The fourth ship of the Awaji class has been launched. The 67 meters-long boat, which has been named 「のうみ」 Nomi (with pennant number MSO 307), entered the water in a ceremony held on October 24 at the company’s factory in Yokohama City. The vessel is expected to enter service with the JMSDF in March 2025.

The construction of a fifth one is also planned and will start soon.

Japan increase the plan from previous 10 (as Sandhi post put) to 12. They also plan to increase the production rate, conpare to present Mogami. Thus they plan to finish 12 in 5 years. The level of automation also in my opinion shown JMSDF try to increase the number of hulls, even with current size of overall manning resources.

The new batch of 12 (being built between 2024-2028) will be a little larger and can accommodate larger missiles while still requiring the same crew size, 90 sailors. Impressive build rate for sure!

Can we affirm that, of the western blocc, outside the USN the JMSDF is the only one that has the size to self maintain(avoiding valleys of death) its fleet without the need for exports? Outside cases like Sweden with only littoral ships.

ROKN also have continues building program for their Navy. Their domestic need is the main thing that keep their yards commercially survive. This eventhough their warships export is bigger then Japanese (which only open to export recently).

SK, Japan, and of course China, all have viable naval construction programs that can survive on domestic needs, also helps that all three have strong commercial ship building albeit Japan not as much these days but the people skills remain strong for all. If the EU was really united it should be possible for the EU to match given the number to great yards in France, Italy, Spain, and Germany but workshare arguments are an obstacle.
