Under what conditions might the Royal Navy have built nuclear carriers in the modern era?
Short answerOnly with funding for a full nuclear CATOBAR force; the actual STOVL choice was shaped by affordability, aircraft politics, and a cancelled five-deck plan.
NotesA nuclear three-carrier force could have supported larger hangars and a full CATOBAR air group, but it required money the Treasury would not commit. Choosing F-35C also risked a political fight in which the aircraft appeared to duplicate Eurofighter and threatened funding for both fleets and the future Tempest programme. STOVL avoided that trap by preserving a distinct shipborne capability. The choice was more coherent when Britain expected two carriers plus three LHDs, all able to share F-35Bs across five flight decks. Cancelling the LHD portion left the two carriers in place but removed much of the interoperability that had justified the wider force design.
