In June 1939, Curts was tapped to serve as communications officer on the staff of the new Commander
Battle Force, Admiral
James O. Richardson. When Richardson became Commander in Chief,
United States Fleet, Curts accompanied him as fleet communications officer. During
Fleet Problem XXI in 1940, the fleet tested its communications procedures under simulated war conditions and discovered serious deficiencies in its existing communications plans. After the exercise, the fleet continued to communicate under simulated war conditions at Curts's recommendation. Richardson declared later: "If the Fleet Problem had resulted in no other advance in naval war readiness and in training, this major step alone would have justified all the money and effort put into the Fleet Problem."
Fleet communications officer Following Kimmel's relief, Curts continued as communications officer on the staff of Kimmel's successor, Admiral
Chester W. Nimitz, relaying messages to Nimitz from the field during the Battles of the
Coral Sea and
Midway. Curts was awarded the
Bronze Star for organizing and establishing a more workable system of joint Army and Navy communications while communications officer for the
Pacific Fleet. In August 1942, Curts was summoned to Washington D.C. to join the staff of Admiral
Ernest J. King, commander in chief of the
United States Fleet. As communications officer for the United States Fleet, Curts received the
Legion of Merit for his part in adopting successful communication agreements and plans between the military services of the United States and its Allies. Curts is credited with developing the numbering system for organizing fleets and task forces that is still used today. On January 6, 1945, while supporting the landings at
Lingayen Gulf,
Columbia was struck by two
kamikaze planes, suffering heavy damage and casualties. Swift damage control measures allowed
Columbia to complete its bombardment and remain in action to support underwater demolition teams. Three days later,
Columbia lay close inshore, with maneuverability hampered by the surrounding landing craft, when struck by a third kamikaze. Again,
Columbia extinguished fires and repaired damage, and was able to complete its bombardment schedule within half an hour of being hit, before departing that night in escort of a group of unloaded transports.{{citation Later that year, as chief of staff and aide to the new Commander,
Fast Carrier Task Force, Pacific Fleet, Vice Admiral
Frederick C. Sherman, Curts attended the
Japanese surrender ceremony aboard the battleship on September 2, 1945. ==Flag officer==
