When introduced, the Nieuport 27 was widely used by the United States Air Service. It was faster than the Nieuport 17 and was armed with twin machine guns. But like previous models, it tended to lose fabric from the upper wing. For this reason it was unpopular with pilots and was soon replaced by the new SPAD XIII. With 40 victories, English ace Philip Fullard scored more victories with the Nieuport 17, Nieuport 23 and Nieuport 27 than any other ace.
