cg47~51使用的宙斯盾系统版本为最早的第一基线baseline1，但cg49~51使用的则有若干改良，包括扩大战情中心的显示屏、电子作战程序自动化、通信系统与国家指挥网络连结、加强作战操作准则及可靠性、加装战术情报系统等，并加装sqq28直升机数据链声纳信号处理系统以配合sh60b反潜直升机cg47、48仍配备sh2flampsi反潜直升机系统。

cg52~58的宙斯盾系统为第二基线baseline2，其改良包括加装战斧巡航导弹的swg2战斧武器火控系统twcs、改良的sqq89反潜战斗系统与link11数据链等，并开始以mk41vls取代mk26，从cg54并开始装设sqr19拖曳阵列声纳，从cg56以后则将原本的sqs53b舰首声纳换装为sqs53b，反潜作战系统升级为sqq89v3。

Bow bridge:

The Aegis system of cg5964 is the third baseline baseline3. The new improvements include the replacement of the new spy1b phased array radar and automatic locking system, the serial operation of the ship's radar, and the replacement of some displays with uyq21.

cg65~73的宙斯盾系统则为基线四baseline4，将原先uyk7计算机换装为uyk4344，运算速度提升四至六倍，并全面换用uyq21显示器。

此外，cg56~67换装新的sqs53b舰首声纳，cg65的反潜作战系统仍为sqq89v3，整合有sqs53bv2舰首声纳、sqr19bv3拖曳声纳与mk116mod7反潜火控系统。

cg66、67的反潜火控系统为sqq89v7，而自cg68起则使用更新型的sqs53c舰首声纳，反潜火控系统为sqq89v6。

Hull weight reduction:

第三艘提康德罗加级舰cg49的设计经过了若干修改，包括变更部分舰体隔舱、扩大消防系统的管道、变更直升机支援设施以操作sh60blampsiii反潜直升机、增加小口径武器弹药携带量等，是第一艘配备sh60b的提康德罗加级舰，配合sh60b的变更也导致cg49重量增加20吨。

In order to improve the increasingly serious overweight problem of the superstructure of the first two ships of this class, CG49 also introduced several weight reduction designs. First, the ballast of the first two ships was eliminated, and secondly, a lighter, smaller and quieter screw-type low-pressure The air compressor replaced the reciprocating compressor used on the first two ships.

Modify the configuration of some accommodation cabins and cold storage, and apply some measures that have been proposed previously but were too late to be used on the first two ships.

For example, the honeycomb configuration of the main engine mixing exhaust pipe and generator exhaust pipe can save 10.6 tons.

cg49 Vincennes:

The Ingalls factory proposed a further weight reduction plan, first replacing the hull materials.

将原本以hts高张力钢板屈服强度约50ksi，相当于345mpa建造的01甲板改由强度更高屈服强度约80ksi，约549mpa的hy80高张力钢板向来给潜艇使用。
