Does the Royal Navy have the best safety record among world navies?
Short answerThe Royal Navy and US Navy rank near the top, with France, Denmark, and Italy also strong, while operational use creates unavoidable risk.
NotesA navy that actively uses ships will expose them to hazards, so raw incident totals are not a complete measure. Reactor shielding and crew radiation in early Soviet and some Chinese nuclear submarines provide a clearer safety discriminator.
