Would a Royal Navy design armed with 15-inch/50 guns have amounted to a super-Hood?
Short answerNot literally, but a modified F3 design with those guns could still have been a very formidable treaty-era capital ship.
NotesThe viewer's comparison draws on US congressional debate about a British design resembling an enlarged Hood. The label is misleading, although a modified F3 arrangement with 15-inch/50 guns could have produced a formidable ship. Its design lineage and weapon fit would differ from both Hood and the eventual Nelson class. The absence of 16-inch guns also weakens the super-Hood comparison. Political shorthand can obscure the characteristics of an actual design family.
