Would a better-designed Supermarine Scimitar have remained in service longer?
Short answerPerhaps, but its twelve-year career was already normal for a rapidly maturing generation of naval jet aircraft.
NotesThe panel resists describing the Scimitar as simply badly designed. Early jet carrier aviation was advancing so quickly that a replacement could already be under development as a new aircraft entered service. Short generations characterized many contemporary designs, including this British type. In that context, service from 1957 to 1969 was a respectable run. A better version might last somewhat longer, but the pace of technological change would still push the fleet toward newer aircraft.
