Curtiss A-1 Triad / AH-1




In February 1911, Curtiss introduced the Triad seaplane, which had both wheels and floats.
The Triad A-1 first flew on July 1, 1911, piloted by Curtiss, for a five minute flight at 25' AGL, and was the US Navy's first airplane (later being designated AH-1) for $4,400.
The A-1 was used in a variety of aerial "firsts"—first cross-country flight, 112 miles in 122 minutes; first (albeit unsuccessful) catapult launch (On 31 April 1912); first night landing on water without lights. It also set a world seaplane altitude record of 900', and completed 285 flights.

The Triad was sold to the British, Russian, German and Japanese navies in 1912. The Japanese naval aviation was founded with the purchase of three Curtiss Triads. In 1912, Curtiss won the Robert Collier Trophy for his development of the seaplane.




A faithful replica was built by a group of fans in San Diego c.1956.
