Could HMS Eagle become an early helicopter assault carrier?
Short answerYes; her tall hangar suits helicopters, and reclassification as an amphibious auxiliary could also release treaty tonnage for another fleet carrier.
NotesHMS Eagle already has a hangar tall enough for the scenario's early helicopters, but her 24-knot speed limits her value with a fast carrier force. Reassigning her in the mid-1930s as an amphibious aviation ship matches the emerging troop-carrying mission. Reducing her armament and classifying her as an auxiliary could remove roughly 22,000 tons from the Royal Navy's carrier allowance. That released tonnage might support another Ark Royal-type fleet carrier while Eagle provides helicopter lift, accommodation, and training. The example connects an operational innovation to treaty accounting and fleet replacement rather than treating conversion as a free addition.
