That was my point with my reply to him...

That's the Shiden M11, a plane that Akagi could already upgrade...

...it's possible that when Akagi got her K2, her ability to upgrade that plane was removed, or Ekel didn't realize (or forgot) that this was a thing that Akagi could do.

...though I also initially read it as Akashi being able to do the upgrade, meaning that it was taken from Akagi (and/or Kaga). Turns out this is not the case though.
