One thing that puzzles me about the picture of the navalised variant of the KF-21N is that it is shown with the same layout as the Air Force KF-21, I am sure that by the time that the naval variant is designed they would have put in internal weapon’s bays instead of being semi recessed.
It depends.
According to the current timetable of the research process, presented by ADD, the technologies needed to develop a full-fledged 5+ Gen fighter jet (which is, probably KF-21 Block III) will be available around 2027; the internal weapons bay, on-board EOTS, conformal antenna, advanced RAS and RAM, indigenous turbofan engines, and etc., are planned to be first utilized and tested on the prototype of the KUS-LW, the Korean Loyal Wingman, around 2025-2027. Making the KF-21 Block III will be the next step, so it should begin in 2028 even if all the things were finished in time with no delays.
Given that the CVX is expected to launch and to be commissioned around early to mid-2030s, the chance of the naval variant of Block III being available before the launch is quite low, unless the RoK gov't decides to make both the Block III's airforce variant and the naval variant in the same time.
