Flying boats and seaplanes were essential across the Atlantic, Pacific, Arctic, and Mediterranean theatres. Their range suited maritime patrol and anti-submarine escort, while the Sunderland's heavy defensive armament earned it the description "flying porcupine." Water operations were especially useful early in the war, before the worldwide airfield network had expanded. Winston Churchill's transatlantic journey aboard a Sunderland also shows their value for communications and secure transport. Churchill was head of government, while the monarch was head of state, and the aircraft could put down on water if trouble prevented it from completing the flight. The same hull and endurance that supported combat missions could help move senior leaders safely.
