The Suffren class makes more sense within France's croiseur de première classe category than as a generic heavy cruiser. French usage retained both eight-inch and six-inch ships within the wider light-cruiser family while distinguishing their rating and role. Treaty categories derived from large light cruisers could obscure the operational identity of later eight-inch designs. French terminology separates treaty gun calibre from the missions and design assumptions that shaped a cruiser.
