Why was HMS Furious converted, and where did her main guns go?
Short answerFurious carried 18-inch guns, which went to monitors after conversion; the exact recipient class remains unresolved.
NotesHMS Furious carried 18-inch guns rather than the 16-inch weapons named in the question. After the ship's conversion, those guns were reassigned to monitors. The Marshall Ney class is considered and then rejected as the recipient. The broad disposal path is clear, while the exact monitor class remains unresolved.
