aren't the spruance, kitt and tico all based on the same hull? I get what you are saying, but it can be done easily, and it is always cheaper to use the experience and basic design you already have....
The Spruance DD were built with some "weight growth margin"...
But the Tico, with AEGIS superstructure, have consumed this margin. As a result, the TICO suffered from "hull-crack" and "serious top weight concerns".
For this, it is very probable that the TICO class was even much more vulnerable than the Spruance again a torpedo hit...
Usually not a very good idea to push a hull to its upper "limit's"
