Standard H-2

The Standard H-2 was an early American Army reconnaissance aircraft, ordered in 1916.

Built by the Standard Aircraft Corporation, the H-2, based on the Sloane H-2, was an open-cockpit three-place tractor biplane, powered by a 125 hp (90 kW) 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 (PMBRA) in 1917, powered by 150 hp (110 kW) Hall-Scott L-4 engines. They were used as trainers between May 1817 and March 1918, although they were considered dangerous.[1]
