Curtiss Twin JN

The Curtiss Twin JN (retrospectively called Model 1B, also known as JN-5) was an American experimental biplane observation aircraft built by Curtiss for the United States Army Air Service.

Based on the successful JN-4, the Twin JN used the same wing structure with an extended span, by enlarging the center section. Control was achieved with the tail of a Curtiss R-4. For power, it employed a pair of 90 hp (67 kW) Curtiss OXX-2s, between the wings.

One aircraft was evaluated by the United States Navy as a twin-float seaplane.
