The Curtiss Aircraft company made quite a business selling fighter aircraft to the U.S. Government and dozens of other nations. The Goshawk II (F11C) didn't sell well in the U.S. but was very popular with foreign countries, so much so that China established a factory and bought a license to produce them in-country. Eventually over 100 served in the Chinese Air Force. It was used by Ernst Udet to demonstrate dive-bombing techniques which eventually led to the JU-87 and Hitler's fascination with dive bombers (and insane projects like the HE-177 four-engine dive bomber).
