The MiG-17 was license-built in both China and Poland. In the early 1950s, the PLAAF obtained a number of Soviet-built MiG-17 Fresco-A day fighters. The Chinese obtained plans for the MiG-17F Fresco-C day fighter in 1955, along with two completed pattern aircraft, 15 knockdown kits, and parts for ten aircraft. The first Chinese-built MiG-17F, produced by the Shenyang factory, performed its initial flight on 19 July 1956 with test pilot Wu Keming at the controls. The MiG-17F was known as the "J-5" in Chinese service, when passed on to other countries, "F-5".
