The United States had extra time to refine its technology before entering the war, yet some admirals assumed Japanese fighting ability was inferior to that of Germany or Italy. That confidence discouraged serious study of recent combat experience. Equipment and doctrine mattered in the resulting Guadalcanal battles. Command judgment also shaped the defeats, so no single weapon explains the outcome.
