Why low hangars constrained later British armored carriers

Were the low hangars and small lifts of Britain's later armored carriers an avoidable design blunder?

Yes; aircraft growth, radar needs, relaxed treaty limits, and available machinery evidence all supported providing more hangar and lift margin.

The comment identifies several warnings available before the later armored carriers were complete. Fleet Air Arm aircraft were growing toward types such as the Barracuda, radar was becoming a confirmed requirement, treaty weight limits had disappeared, and machinery trials showed usable power margins. Despite those signals, the Implacable-class design retained low hangar clearance and small lifts that restricted future aircraft handling. The reply agrees that this was an avoidable design shortcoming rather than a limit imposed solely by the earliest armored-carrier concept.
