Did the Tiger-class light cruisers end 84 years of continuous cruiser construction with a sad whimper?
Short answerThey were the last cruisers produced; the description of that ending as a sad whimper remains the questioner's judgment.
NotesThe Tiger class is accepted as the final class in Britain's cruiser-construction sequence. Clarke declines the question's description of a sad whimper and treats it simply as the end of the sequence.
