Leadership change narrows Supermarine's wartime choices

The removal of a senior Supermarine figure because his wife was German disrupted the design organization just as war intensified official pressure. His newly installed successor would have had less confidence and institutional leverage to insist that the company could sustain both a naval fighter and the expanding land-fighter program. The Air Ministry's immediate priority was to secure Spitfire production rather than preserve every promising parallel design. The outcome is explained as a collision of wartime priorities and personal circumstances, without implying a conspiracy against naval aviation.
