Would a British Canadair Argus maritime-patrol fleet lead to an airborne-early-warning version?
Short answerProbably, because Britain needed an AEW aircraft and the Argus airframe fitted the requirement.
NotesThe counterfactual replaces Britain's maritime-patrol path with the Canadair Argus. The airframe would probably follow the Shackleton into an airborne-early-warning role because Britain still needs that capability. The Argus profile appears suitable for carrying the required systems and endurance. The AEW version would be a mission-driven derivative of the Canadian patrol aircraft.
