Curtiss JN-6H

The Curtiss JN-6H, also the Model 1F, was a biplane trainer that Curtiss built for the United States Army Air Service during the First World War. It grew from the one-off JN-5H advanced trainer and had a better aileron operating mechanism than the JN-4H, whose airframe it otherwise closely matched, with the same 150 hp Hispano-Suiza 8A V8 weighing 408 lb. It served as a bomber trainer, a dual-control and a single-control gunnery trainer, an observation trainer and a pursuit trainer, 1,035 in all, five going to the Navy. Some were later modernised as the JNH and then the JNS, the JN Standard, with a 180 hp Wright-Hispano E or a 150 hp Wright-Hispano I engine.
