English: The NC-4 was a Curtiss NC flying boat that was the first aircraft to fly across the Atlantic Ocean, albeit not non-stop. The NC designation was derived from the collaborative efforts of the Navy (N) and Curtiss (C). The NC series flying boats were designed to meet wartime needs, and after the end of World War I they were sent overseas to validate the design concept.

The aircraft was designed by Glenn Curtiss and his team, and manufactured by Curtiss Aeroplane and Motor Company, with the hull built by the Herreshoff Manufacturing Corporation in Bristol, Rhode Island.

In May 1919, a crew of United States Navy and US Coast Guard aviators flew the NC-4 from New York State to Lisbon, Portugal, over the course of 19 days. This included time for stops of numerous repairs and for crewmen's rest, with stops along the way in Massachusetts, Nova Scotia (on the mainland), Newfoundland, and twice in the Azores Islands. Then its flight from the Azores to Lisbon completed the first transatlantic flight between North America and Europe, and two more flights from Lisbon to northwestern Spain to Plymouth, England, completed the first flight between North America and Great Britain. This accomplishment was somewhat eclipsed in the minds of the public by the first nonstop transatlantic flight, made by the Royal Air Force pilots John Alcock and Arthur Whitten Brown two weeks later.

After arriving at Plymouth, England, the crewmen of the NC-4, who had been reunited with the crewmen of the less-successful NC-1 and NC-3, went by train to London, and there they received a tumultuous welcome. Next, they visited Paris, France, to be lionized again.

The NC-4 was dismantled in Plymouth, and then loaded onto USS Aroostook, the base ship for the Curtiss NC's transatlantic flight, for the return journey to the United States. Aroostook arriving in New York Harbor on 2 July 1919.

Following the return of all three of the aircrews on board the ocean liner USS Zeppelin, a goodwill tour of the East Coast of the United States and the Gulf Coast of the Southern States was carried out by the aircrew.

On 9 February 1929, Congress passed Public Law 70-714 (45 Stat. 1157), awarding Congressional Gold Medals to Lt. Commander John H. Towers for "conceiving, organizing, and commanding the first trans-Atlantic flight", and the six men of the flight crew "for their extraordinary achievement in making the first successful trans-Atlantic flight, in the United States naval flying boat NC-4, in May 1919." The Navy created a military decoration known as the NC-4 Medal.

It is very rare that a Congressional Gold Medal in miniature form be authorized for wear on a naval or military uniform.

The NC-4 is property of the Smithsonian Institution, since it was given to that institution by the Navy after its return home. However, this aircraft was too large to be housed in either the older Smithsonian Arts & Industries Building in Washington, D.C., or in its successor, the 1976-completed National Air and Space Museum main building, also in Washington. A smaller model of the NC-4 is kept in the Milestones of Flight Gallery in the National Air and Space Museum, a place of honor, along with the original Wright Flyer of 1903; Charles Lindbergh's Spirit of St. Louis of 1927; Chuck Yeager's Glamorous Glennis X-1 rocket plane of 1947, and an X-15 rocket aircraft. As of 1974, the reassembled NC-4 is on loan from the Smithsonian to the National Museum of Naval Aviation in Pensacola, Florida.
