Was the Bouvines class protected by Krupp armor or Harvey armor?
Short answerThe evidence appears mixed; some sources suggest Krupp armor, but the identification is not certain.
NotesBouvines carried roughly 2,270 tons of armor on a ship of about 6,800 tons. Available references indicate that the protection may have mixed armor types. Some describe it theoretically as Krupp armor, while other material points away from a uniform Krupp fit. The uncertainty matters because published specifications can flatten a complex or transitional armor scheme into one label.
