Would HMS Queen Mary and surviving Invincible-class battlecruisers have been scrapped as obsolete in the 1920s?
Short answerYes, although the Royal Navy might first have counted the surviving hulls in its treaty-tonnage position.
NotesThe early battlecruisers would have been scrapped as obsolete in the 1920s even if they had survived the First World War. Before disposal, they would probably have counted toward the tonnage the Royal Navy claimed under the treaty system.
