Would larger treaty carriers create enough development to produce a Malta-class successor?
Short answerProbably; an Audacious-scale treaty generation could be followed by Malta-class or equivalent wartime carriers once displacement limits ended.
NotesA standard allowance of roughly 27,500 tons would already bring a British treaty carrier close to Audacious-class scale. Regular construction at that size would give designers and yards experience with substantially larger fleet carriers before wartime. Once treaty limits disappeared, the next generation could plausibly develop into the Malta class or a comparable design. This is a broad design path rather than a claim that the historical Malta plans would appear unchanged.
