Aegis class super destroyer

After reading the Top 10 Most Powerful Destroyers In The World, I came up with an idea for an Aegis super destroyer, which I’ll just call the Aegis class super destroyer.
I’ll base it on the Sejong the Great-class destroyer, so I guess that you can consider the Aegis class super destroyer a redesign.

After doing a little reading about sensory systems, propulsion systems, and missile systems, .
I will start from the most noticeable external differences into the differences in the propulsion system.
. Addition of 4-faced X-band Active Electronically Scanned Array Radar, primarily for fire control and provides target illumination for the ESSM in the terminal intercept phase.
. Addition of 4-faced C-band Active Electronically Scanned Array Radar, primarily for long range search and tracking.
. If necessary, a secondary volume search radar, perhaps something similar to the Thales Nederland NS100, will be included.
. AN/SPY-6.
. Possible addition of the AN/SPS-67 C-band radar.
. Possible addition of the Sagem VAMPIR IR search and track system for passive detection of cruise missiles, aircraft, and other asymmetric threats.
. Two Pantsir-M close-in weapons systems will be in place of the Goalkeeper CIWS and RIM-116 Rolling Airframe Missiles.
. The smokestacks are shielded to reduce the vessel's infrared/near-infrared and heat signature.
. The propulsion system, instead of combined gas and gas, will be an integrated electric propulsion system with two Rolls-Royce MT30 turbine engines and two MTU M71L diesel engines, with the engines being mounted on anti-vibration mounts, making the vessel quieter and less detectable to passive sonars. Moreover, noise is reduced, making for more pleasant living and working conditions for everyone on board.
Alternatively, a nuclear reactor from a submarine may also be used to generate electricity.
. One Mauser BK-27 cannon is mounted on each side just behind the main superstructure, mainly to engage small watercraft, and act as backup CIWS systems.
. Examples of missiles used:
Surface-to-surface:
BrahMos-II anti-ship missile.
3M22 Zircon anti-ship missile.
P1000 Vulcan anti-ship missile (in external launch tubes).
3M14T cruise missile.
3M54K anti-submarine missile.
Surface-to-air:
S-400/S-500.
The aforementioned missiles used would have their electronics modified to integrate with the ship’s Aegis system.

. It externally resembles the real-life Chinese Type 055 destroyer.

. Will, sometime in the early 21st century, be upgraded with a low-probability-of-intercept radar (LPIR).

. Earlier examples built in the 20th century may not have all 21st century electronic countermeasures, but will be upgraded in the 21st century.
