An earlier description identified the bridge and propulsion plant as areas without significant layout changes. The spoken comparison of the overlays challenges the claim about the bridge by pointing to a changed position and structure. American-built equipment requirements also displaced systems around which the European parent had been arranged. Radar choices determine what the superstructure must support, and changing those arrangements affects other equipment and internal spaces. Many individually small substitutions can therefore produce a large redesign without introducing an entirely new technology. Reported February 2025 comments by Navy officials acknowledge that adapting another navy's design was harder than expected and could be less straightforward than designing a new ship.

How equipment substitutions spread through a parent design
Bridge-layout comparisons and American equipment substitutions explain how individually small changes can consume a parent design's expected advantages.
