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 (90 kW) Hall-Scott A-5 engine.

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.
