Could Henderson have got Implacable and Audacious built sooner?
Short answerHis influence still faced wartime escort priorities and the immediate threat to Britain's Atlantic imports; the exchange does not establish that earlier completion was achievable.
NotesJamie questions whether Henderson's influence could have overcome the demands of a war threatening Britain's food and supply imports. Immediate escort requirements changed which ships construction capacity had to support. Alex accepts that war forced attention onto urgent needs, while stressing that the rearmament programme had assumed several more years before fighting began. The expected period mentioned here is 1942-44. Success in securing peacetime support therefore leaves the earlier-completion counterfactual unresolved.
