The Huff-Daland Type XV Training Water-Cooled TW-5 was a biplane trainer designed by the Huff-Daland Aero Corporation in the early 1920s for the United States Army Air Service.

Design and development

It was a development of the TA-6 (which itself was a one-off redesigned TA-2 with a 220 hp Lawrance J-1 air-cooled engine) but powered by a 190 hp Wright-Hispano E2. In 1924, the letter-and-number system was revised, and the TW-5 became an Advanced Trainer AT-1. In 1927, Huff-Daland Aero Corporation became a division of Keystone Aircraft Corporation.

Operational history

Versions of the AT-1 were built for the United States Navy as training and observation aircraft.
