Long-range reconnaissance could be decisive when neither side enjoyed an intelligence advantage. The Catalina paired that strategic value with anti-submarine, strike, search-and-rescue, and commercial roles. Its quoted range of 2,119 nautical miles gave a theoretical outward reach of about a thousand miles, though a practical search pattern would reduce that radius. A squadron could therefore search an enormous area from one base, giving commanders the information needed to direct forces and use their weapons effectively.
