Dzisiejszy okręt to wczesne wcielenie idei Johna Fishera – coś co można by z przymrużeniem oka nazwać „wielkim lekkim krążownikiem epoki predrednotów”. Generalnie chodzi o okręt z pancernikowym kalibrem artylerii, ale od pancerników istotnie szybszy. Konstrukcyjnie jest to krążownik pancernopokładowy, któremu główną ochronę zapewniają skosy pokładu pancernego wsparte zasobniami węglowymi. Zastosowaniem takiej jednostki może być rozpoznanie na rzecz floty liniowej lub tworzenie jej szybkiego skrzydła, ewentualnie dobijanie uszkodzonych wrogich pancerników.
