The investigating committee identified Ark Royal's dependence on electricity as a major vulnerability because the loss of boilers and steam-driven dynamos left no diesel backup for pumps and other damage-control systems. It also criticized boiler-room bulkheads, intake arrangements, and the uninterrupted fan flat that carried water across the ship. These design findings explain why the initial flooding became so difficult to contain once power was lost, alongside the failures of command. The inquiry could not have originated the Illustrious-class design because those carriers were already commissioned before the report was completed in February 1942. Retrofitting remained possible, while the later Implacable and especially Audacious designs offered more plausible opportunities for the findings to influence construction.

The inquiry's lessons for carrier survivability
The inquiry identified vulnerable machinery-space flooding paths and an all-electric ship without backup diesel generation, while the discussion weighs where those lessons could have influenced later work.
