Did the Queen Elizabeth class itself establish the capital-ship standard used by the Washington Naval Treaty?
Short answerNot by itself. The class began a design progression whose later ships helped define the treaty-era benchmark.
NotesQueen Elizabeth began a design process without directly setting a treaty limit. The class demonstrated a combination of heavy guns, protection, and greater speed that later capital ships developed further. Those successors formed the immediate comparison set when treaty standards emerged. This distinction preserves the technological lineage without turning the Washington settlement into a one-ship story.
