from America to Europe to be attempted by Navy Seaplane Division Number 1. Robinson got underway from Norfolk on 30 April, arrived at Halifax, Nova Scotia, 4 May 1919, and stood out toward the entrance of the harbor on the afternoon of 8 May. At 1944, she sighted the first of the Navy seaplanes, the NC-3, approach the harbor on the first leg of the transatlantic flight. Two days later, Robinson took station at sea to assist in guarding the flight of the two seaplanes to Trepassey Bay, Newfoundland, then returned to Halifax 11 May and got underway on 14 May to act as plane guard for seaplane NC-4 which had been delayed by repairs at Chatham Naval Air Station, and passed overhead at 1645, on 15 May, to join the other two seaplanes at Trepassey Bay. After NC-4 faded from view, Robinson set course for station on the Azores route to be followed by the seaplanes from Trepassey Bay, 16 May 1919. These seaplanes would be guided on their 1,380-mile flight to the Azores, by Robinson and other destroyers who poured smoke from their funnels in daylight and fired starshells or turned on searchlights during the night. The first seaplane passed Robinson abeam an hour before midnight of 16 May 1919, and the two others also passed within the next 20 minutes. The NC-4 covered the flight in 15 hours and 13 minutes setting down at Horta, the emergency stop in the Azores Islands. This seaplane had found its way above the dense fog which completely blinded the pilots of the others. An hour before the NC-4 landed, the NC-1 was forced to the water about off Flores Island and the NC-3 had also descended about from Fayal. The NC-1 sank in the heavy seas and Robinson joined in the search for the NC-3 which refused all assistance and finally taxied to Ponta Delgada under its own power. Robinson anchored at Horta, Fayal Island, the afternoon of 19 May and stood out of the harbor the next morning to transport newspaper reports to Ponta Delgada where she arrived that afternoon. On 25 May 1919, she was en route to Station Number Seven () to cover the fourth leg of the transoceanic flight of the lone NC-4. She sighted the seaplane at 1330 on the afternoon of 26 May and the NC-4 faded from view on its way to a
