日本是世界上较早研发航空母舰的国家之一。日本在1922年建造的“凤翔”号航母被认为是世界上第一艘标准的航空母舰。第二次世界大战时期，日本曾建造了11艘舰队航母和若干轻型航母，一度横行海上，成为其野心高度膨胀的催化剂，日本自从明治维新后大量吸收了西方的文化，在军国主义兴起后，更是醉心在坚船利炮上面。和各列强海军一样，最初的时候日本海军内部也曾有过航空母舰与战列舰孰轻孰重的激烈争议，但仍从1911年就开始了航空母舰的开发工作。1952年起日本推行直升机航母（见日本百年航母词条的介绍），现在，2017年时日本已经服役了4艘直升机航母。...

Awesome : It was a type of carrier which was planned a construction of three carrier ships until Midway 's defeat.

Could be G-14 sister ships of Taiho ?

 

[Tzoli]

G-14: The Japanese Midway, basically a Shinano sized 50.000ton super carrier which was designed as a carrier from the start (to our current knowledge)
G-15: Improved Taiho design

 

[airman]

G-14 could be a Shinano class with less ton of Shinano. (50.000 ton) or could be have been a two larger Taiho based on Shinano dimension. G-14 design i suppose was lost with the war.

ceccherini do you know the book title or ISBN that you posted those two pages from at the beginning of this thread?

Sorry but no, I don't.

 

[Tzoli]

Any idea where did you find the images?
Reverse image search did not produced any results

After some research I've found the original publication. https://page.auctions.yahoo.co.jp/jp/auction/u375691359

Thanks this could help, especially the 6th page

G-14 was sized between 45.000 and 50.000 ton .

What is the folding wing twin engine plane in the first photo?

I have finally found the answer to this question! It was a twin-engined concept for the next aircraft to replace the D3A, though this eventually evolved into the single-engined D4Y, interestingly enough.

 

[Airborne2001]

Do any schematica of the G-14 exist? I know that it most likely is comparable in looks to the US Midway class, but I am still intrigued by what it could possibly look like.

 

[Tzoli]

The one in the first post is the only artist impression so far no official drawings I've seen. I always thought of a Shinano sized carrier with two hanger levels, Hurricane like bow and general Junyo/Taiho/Shinano like bridge. with at least 4 but maximum 6 twin 10cm AA guns per side. Catapult and 40mm Type 5 AA guns if I feel like a very advanced carrier otherwise 25mm guns and maybe 12cm AA rocket launchers.

i found this strange link in japanese wikipedia, is some easy to translate with wikipedia google translator: https://ja.wikipedia.org/wiki/G18_(空母)
This other link have a very big ¿Cyberbibliography? or list of links in his Notes section:

Yes G-18 was the last design number of the IJN for an aircraft carrier. By it's size it is a built up CVL similar to Ibuki
