Early Aegis deckhouses weighed about 200 tons apiece and were too heavy for the Virginia-class hull. The design began as a nuclear destroyer-leader Aegis study but grew into a clean-sheet strike cruiser while retaining destroyer-type reactors. Cruiser standards demanded redundancy and protection beyond the cheaper destroyer-derived proposals. After the strike cruiser was cancelled in 1977, CGN-42 emerged as a more austere design with an improved layout but without the strike cruiser's protection or flag facilities. The missing command spaces matter because a task-group cruiser needs leadership capacity as well as sensors and weapons.

Why Aegis forced a clean-sheet strike cruiser
The weight and growth of early Aegis equipment pushed the nuclear strike cruiser beyond a Virginia conversion and into a protected, command-capable clean-sheet design.
