The shipboard illumination-rocket puzzle

A museum ship carried numerous launchers described as using illumination rockets. The number of ready launchers and their ability to aim independently from the guns raise the possibility that another warhead might once have been contemplated. No proof has been found, so this remains a naval historian's suspicion rather than a conclusion. Physical arrangements can generate a useful research question, but the object alone does not establish doctrine or ammunition supply. The passage is a concise example of responsible source criticism during a ship visit.
