Curtiss JN-6H
# Curtiss JN-6H

The Curtiss JN-6H (Model 1F) was an American biplane trainer aircraft built by Curtiss for the United States Army Air Service during World War I.

## Design and development

Developed from the one-off JN-5H advanced trainer, the 6H had a superior aileron operation mechanism. It was used in a variety of roles, with stick and rudder in either one seat or both: JN-6HB single-control bomber trainer (154 built), JN-6HG-1 dual-control gunnery trainer (560 built), JN-6HG-2 single-control gunnery trainer (90 built), JN-6HO single-control observation trainer (106 built),and JN-6HP single-control pursuit trainer (125 built), a total of 1,035; five went to the Navy.

The airframe did not differ substantially from the JN-4H (Model 1E), and used the same 150 hp (112 kW) Hispano-Suiza 8A ("Hisso") V8, which weighed 408 lb (185 kg).

Some of the aircraft were modernized as the Curtiss JNH and later to the Curtiss JNS (JN Standard) with either a 180 hp (134 kW) Wright-Hispano E (as JNS-E) or 150 hp (112 kW) Wright-Hispano I engine (as JNS-I).
