PZL Swidnik

Produced jet fighters up to 1951, when defense cuts were made; then turned to Mi-1/SM-1 helicopter production and a helicopter design office was formed. Initially, Polish aircraft, license-built or native, were produced under name of PZL: Polskie Zaklady Lotnicze. In 1957 WSK renamed WSK im Zygmunta Puiawskiego. Production of SM-1 ended late 1960s and Mi-2 production began in 1965/

Under political reorganization in 1956, the Polish aircraft industry was revived with production of Soviet aircraft and some indigenous types. In foreign markets most Polish aircraft subsequently appeared under the PZL title, such as the PZL-101 Gawron and PZL-104 Wilga utility aircraft of 1960 and 1962 respectively, the first being a development of the Yak-12. The Gawron was used extensively as an agricultural aircraft, along with the PZL-built An-2 biplane, but later purpose-built dusters and sprayers were built. PZL types are produced under three separate organizations: PZL "Warszawa-Okecie" SA, WSK "PZL-Mielec" SA, and PZL-Swidnik SA.
PZL-Swidnik undertakes helicopter production and development. Origins in 1951, manufacturing components for LiM-1 fighters (Polish version of MiG-15). First helicopter production was SM-1 (Mil Mi-1), of which huge numbers were completed, followed by SM-2. Mil Mi-2 was first flown in Soviet Union in September 1961 as twin-turboshaft helicopter, but all production transferred to Poland in 1964, allowing first Polish-built Mi-2 to fly in November 1965; production lasted until 1996, after 5,450 had been built in a large number of variants for civil and military roles. Kania first flown June 1979 as modernized development of Mi-2 using U.S. Allison turboshaft engines and AlliedSignal Bendix/King avionics, but only some 13 built to date. W- 3 Sokol first flown November 1979 as 12-passenger civil/military intermediate multipurpose helicopter with twin turboshafts, of which well over 100 built to date and some exported; many variants, Polish armed forces versions including W-3RM Anakonda for air/sea rescue, and W-3W Sokol and similar W-3WA each with 23 mm cannon and outriggers for missiles, rockets and other weapons; SW- 5 is anticipated development of W-3 using French avionics. S-1W Huzar antiarmor and attack helicopter expected to fly 1999 and be built for the Polish armed forces; based on W-3 design. Four/five-seat SW-4 light utility single-turboshaft helicopter first flew October 1996.
