Curtiss N-9H trainer at National Air & Space Museum’s Udvar-Hazy facility.
The N-9 family was developed by the Curtiss Aeroplane and Motor Company specifically for the United States Navy as an advanced seaplane trainer
While the NH-9 and the JN-4 Jenny share basic lineage, the N-9H featured a larger wingspan, heavily reinforced airframe, and a much more powerful engine to handle the weight of water operations
