Why was the Revenge class treated as cheaper when its unit cost was close to the Queen Elizabeth class?
Short answerThe quoted saving of about £300,000 per ship becomes £2.4 million across eight hulls.
NotesThe figures quoted in the question imply a saving of about £300,000 per ship. Across eight planned hulls, that becomes £2.4 million compared with eight more Queen Elizabeths or improved versions of that design. A small difference in unit cost could therefore matter at programme level. Political concern over apparently modest savings helps explain the cheaper design's attraction.
