The SZD-9 Bocian (Polish: "Stork") is a multi-purpose two-seat sailplane that was designed and built in Poland at Szybowcowy Zakład Doświadczalny (Glider Experimental Works) in Bielsko-Biała, beginning in 1952. It was designed to be capable of fulfilling the needs of every area from training to competition flying.
Main designer was Marian Wasilewski, with Roman Zatwarnicki and Justyn Sandauer. The prototype SZD-9 flew for the first time on 10 March 1952, piloted by Adam Zientek. After flight testing was completed, suggested changes were incorporated into the design and production began, as SZD-9bis Bocian-1A (or simply "Bocian A"). The first production unit flew for the first time on 13 March 1953, and 11 units were built.
Apart from use in Poland, the type was exported to 27 countries, including Austria, Australia, Belgium, China, France, Greece, India, Norway, former East Germany and West Germany, Switzerland, Tunisia, Turkey, Venezuela, United Kingdom, and the Soviet Union. Polish pilots set many international records flying SZD-9s.
