Which Royal Navy ships might it have been better not to acquire?
Short answerSeveral notorious classes are candidates, but a flawed ship that filled a necessary role should usually be replaced by a better design rather than simply omitted.
NotesCourageous, Glorious, Furious, the Hawkins class, HMS Captain, and K-class submarines appear among the strongest candidates for avoidance. The Dido class is different because its intended role still had to be filled. A flawed ship can be worth building when the alternative is leaving a required capability empty. The better counterfactual is often a replacement design rather than simple cancellation.
