Standard H-2


The Standard H-2 was an early American Army reconnaissance aircraft, ordered in 1916. The H-2 was built by the Standard Aircraft Corporation, and previously known as the Sloane H-2. It was an open-cockpit three-place tractor biplane, powered by a 125 hp Hall-Scott A-5 engine. Only three were built.
An improved version, the H-3, with the same engine, earned an order for nine aircraft, while the Navy ordered three with floats as the H-4H.
Two Standard H-3s were sold by the US Army to Japan, where a further three were built by the Provisional Military Balloon Research Association in 1917, powered by Hall-Scott L-4 engines. They were used as trainers between May 1917 and March 1918, although they were considered dangerous.
