WSK PZL-Mielec / PZL Mielec
The PZL WP2 factory in Mielec became a part of Heinkel during the German occupation of Poland. After the war the factory, named first PZL No.1 works, then from 1949 WSK-Mielec, and later WSK "PZL-Mielec", became the biggest post-war Polish aircraft producer. It manufactured mostly licensed Soviet planes, such as the Antonov An-2 transport biplane and jet fighters such as the MiG-15 (as Lim-1 and Lim-2) and MiG-17 (as Lim-5 and Lim-6). It also produced the Polish-designed TS-8 Bies piston trainer and TS-11 Iskra jet trainer, and the PZL M-15 Belphegor the world's only jet agricultural plane and the world's slowest jet. Large numbers of aircraft were exported abroad, mostly to the USSR. From the 1970s onward it produced mostly its own developments of licensed civil aircraft, the best known are the M-18 Dromader agricultural plane, which was exported to numerous countries, and the PZL M-28 Skytruck/Bryza light transport plane. In 1998 the state factory WSK PZL-Mielec went bankrupt and was changed into the state-owned Polskie Zakłady Lotnicze Sp.z o.o. (Polish Aviation Works) (PZL Mielec).
On March 16, 2007, PZL Mielec was purchased by the Sikorsky Aircraft Corporation, a unit of United Technologies Corporation (UTX). It still produces M-18 and M-28 aircraft.
