The PZL W-3 Sokół is a medium-size, twin-engine, multipurpose helicopter developed and manufactured by Polish helicopter company PZL-Świdnik, now owned by Leonardo. It was the first helicopter entirely designed and produced in Poland.
During 1973, work commenced upon what would become the W-3 Sokół at PZL Świdnik; design work was performed by an in-house team led by aeronautical engineer Stanisław Kamiński. A major influence on the design was the perceived demands from both military and civilian aviation across the Soviet Union, which was envisioned to serve as the major operator of the type. On 16 November 1979, the Sokół conducted its maiden flight. Following an intensive test programme, type certification for the helicopter was received from aviation authorities in Poland, Russia, the United States and Germany.
During May 1993, certification of the Sokol to Federal Aviation Administration (FAA) FAR Part 29 standards was granted; it was followed by the receipt of German certification during December of that year. During 1985, low rate production of the Sokół commenced. In June 1996, the 100th Sokół was completed by the company.
