Who manufactured the propeller shafts for the Queen Elizabeth-class carriers?
Short answerRolls-Royce's Kristinehamn facility in Sweden produced the shafts because the United Kingdom no longer retained the plant needed to manufacture components at that scale.
NotesThe propeller shaft is physically simple to describe but difficult to manufacture at carrier scale. Rolls-Royce produced the shafts at its Swedish facility in Kristinehamn. The work went abroad because Britain no longer possessed the necessary manufacturing facility. This watch point makes industrial sovereignty concrete by tracing a major British carrier's propulsion train to a specialized overseas plant.
