I think I can ID some of the ships not in Kancolle yet (or ever, in the case of the AVTs)

2nd Carrier Division: DD Yuuzuki
3rd Carrier Division: DD Yuukaze
4th Carrier Division: CVE Taiyou, DDs Shiokaze and Hokaze
12th Seaplane Tender Division: AV Kamikawa Maru, AV Sanyo Maru
21st Naval Air Flotilla: AVT Katsuragi Maru
22nd Naval Air Flotilla: AVT Fujikawa Maru
23rd Naval Air Flotilla: AVT Komaki Maru
24th Naval Air Flotilla: AV Kamoi (the miko), AVT Goshu Maru (the one behind her that isn't a fairy)

I'm using AVT as in the old designation for aircraft transport rather than the slightly less old designation for training carrier

I regret looking them up, because I like freddy's Taiyou and Kamoi designs and the real ones are probably gonna disappoint me...

Look at that RJ face...
I really love it

RJ is so cooooooooool!

Agreed

Some names do not appear to be well standardized (or even present in) English sources. All the numbered carrier divisions here use the same naming format in Japanese, but English sources adjust names based on size (small escort fleets like the 12th are called "Flotilla" instead of "Division", for example).

tsukamoto_minori has a couple of cool/badass RJ images, for those that are interested.

I see a Reimu.

... and this picture got updated to replace the Kasuga Maru and Kamoi stand-ins into their actual in-game appearences.
