Why fleets need quality, quantity, and balance

Japan's big-ship and big-gun emphasis sought deterrence through individually exceptional combatants. Such ships are politically attractive because leaders can advertise them as the biggest, toughest, or most advanced in the world. The harder case is to fund numerous average ships that can be produced at a sustainable price and perform the fleet's routine work. The first-rate and third-rate example shows how several ordinary combatants can overwhelm isolated excellence, while elite ships become much more effective when backed by enough supporting hulls. Quality and quantity are complements, and a navy that neglects either side loses resilience across its missions.
