Was a Buccaneer S.1 crash the final straw that forced the Royal Navy to retire the variant?
Short answerNot by itself; the Navy already intended to move to the S.2, and the crash accelerated that plan.
NotesThe Royal Navy was already trying to move from the Buccaneer S.1 to the improved S.2 when the crash occurred. The accident accelerated that transition by adding urgency to an established direction of travel. A visible disaster can speed procurement and safety decisions without being their original cause.
