Which was the stronger navy as an organisation in the Second World War, the Regia Marina or the Kriegsmarine?
Short answerThe Regia Marina, because it could assemble a far larger and more coherent surface fleet against the Royal Navy.
NotesThe Regia Marina had the advantage in hull numbers and overall fleet organisation during the Second World War. The Italian force assembled around Cape Matapan represents a scale of surface threat that the Kriegsmarine could not normally reproduce. Admiral Andrew Cunningham's Mediterranean command shows how seriously the Royal Navy took this opponent. The comparison distinguishes the effectiveness of individual German ships or U-boats from the institutional challenge posed by an organised Italian battle fleet.
