Would the Royal Navy have joined the TSR-2 programme or retained the Blackburn Buccaneer?
Short answerIt would have retained the Buccaneer because making TSR-2 carrier-capable would have required redesigning the aircraft.
NotesTSR-2's airframe and integrated system were designed around land operations. Adapting it for a carrier would have meant redesigning the aircraft rather than changing a few components. The naval Buccaneer therefore remained the practical Royal Navy choice. The comparison shows how an aircraft's original operating environment constrains later roles.
