history

The NF-1 (Naval Fighter No. 1) was a derivative of the P-35 design and entered the 1937 US Navy competition for a carrier-based single - seat fighter aircraft. Equipped with a Wright R- 1820-22 Cyclone nine-cylinder radial engine with 950 take-off power, the machine was transferred to NAS Anacostia on September 24, 1937 for comparison purposes . The NF-1 was given the official US Navy designation XFN-1 , but this was only given for formal reasons, as no production order was placed by the Navy. The aircraft only bore the civil aircraft registration number NX1254 as a marking .

The NF-1 initially flew with the vertical windshield that the AP-1 used; Before the transfer to Anacostia, however, they were replaced by a conventional design, and the landing gear fairing was also removed in an early phase of the comparison flight.

The competition flights showed that the NF-1 lacked the good flight characteristics required for a carrier-supported fighter at low speeds. The US Navy therefore refused to acquire the model, whereupon Seversky stopped further development.
