The Curtiss R-6 was the US Navy's first torpedo-bomber. It was derived from the N-9 trainer. While the first 36 were ordered with the 200hp Curtiss engine, the rest were built with the 400hp Liberty and were renamed the R-6L. They were used for patrols out of the Azores. While the type was withdrawn from active service after the war, twenty-five were still on hand in 1921.
