For AEGIS, there is already similar local made intergrated naval combat system. Although, I don't give it an official name yet.
The balistic submarine like Ohio-class is deemed unnecessary because the role to launch cruise missile can be done by missile cruiser warship and fixed or mobile platform on land.
GF 4.5 is a 4.5th Generation Jet Fighter. It is based on IFX/KFX/KF-21 Boramae. The 5th Gen like F-35 is still in research.
The Emperor-class battleship in my story is based on Iowa for majority specs, Bismarck for main turrets, and Yamato for hull.
Thanks for your suggestion. If you have more ideas, you can write those here.
