Azur Lane's G14 carrier and I-400 submarine references

What interests the panel about the G14 carrier and I-404 in Azur Lane's anniversary announcements?

G14 draws attention to an unbuilt armored-carrier design, while I-404 raises questions about how a submarine carrying only a few floatplanes receives a carrier-like aviation rating.

The announced Azur Lane ships prompt a short discussion of the historical designs behind the game. G14 is identified as an unbuilt Japanese armored-carrier proposal, while Taiho Kai is distinguished as G15. The panel welcomes attention to a carrier design that receives little discussion because it was never completed. I-404 prompts a different question: how the game will represent an I-400-class submarine with an aviation rating comparable to some carriers. The real payload cited is three floatplanes with roughly 800 kg bombs, so the rating is treated as a game abstraction rather than an equivalent carrier air group.
