This Curtiss fighter of 1920 was built to cover a USAS Engineering Division requirement for a night fighter (P-ursuit N-ight). Clearly inspired in the German Fokker D.VII, the PN-1 employed a similar construction structure and was powered by the very German-looking 230hp Liberty 6 inline engine – a sort of half-Liberty 12V. The only of the two built which flew took its maiden flight in 1921, Uninspiring performances prevented further development and the contract was cancelled.
That biplane configuration couldn’t be more “Fokker’s”. In fact, like the D.VII the PN-1 was built as a full-cantilever biplane, but those interplane struts were added before delivery.
