Most likely, Shoukaku K2 will come with this: Prototype Nanzan

Either that, or another land based airplane that would otherwise be too heavy to launch from a flight deck with limited length.

Nanzan was excellent at high speeds, but required a longer runway to take-off from. Which is where the catapult comes into play.
