Ship dates are usually the easiest facts to establish, while displacement, length, and beam still carry measurement limits. Physical constraints such as dry docks and canal passages can narrow the uncertainty. Historical conclusions remain more open because researchers bring different evidence and arguments to the same event. That method matters here because the familiar wartime origin story of escort carriers must be tested against earlier plans and precedents.
