PZL-Świdnik
aircraft manufacturer in Poland
PZL-Świdnik S.A. (Wytwórnia Sprzętu Komunikacyjnego PZL-Świdnik S.A.) is the biggest helicopter manufacturer in Poland. Its main products are PZL W-3 Sokół and PZL SW-4 Puszczyk helicopters. In early 2010 the factory was acquired by AgustaWestland, today Leonardo.
History
History of plant establishment dating back to 1920, when in Lublin opened the first aircraft factory "Plage i Laśkiewicz". After World War II, part of the senior instructors staff incorporated into the newly formed "Wytwórnia Sprzętu Komunikacyjnego".
In 1951 a third national aerospace factory, WSK-Świdnik, was built in Świdnik, and in 1957 it was renamed to WSK PZL-Świdnik. Since 1956 it has become one of the world's major helicopter manufacturers, producing helicopters under the Soviet licence, starting with the SM-1 (Mil Mi-1). Świdnik was the main producer of the Mi-1 and exclusive producer of the widely used in the world Mil Mi-2. Since the late 1980s, Świdnik has been producing a Polish-designed medium helicopter PZL W-3 Sokół. It also produces a light helicopter, the PZL SW-4 Puszczyk.
This brief starts where responsible research should: with the source description of “PZL-Świdnik” as aircraft manufacturer in Poland. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as aircraft manufacturer in Poland. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Oct 12, 2025. The linked authority identifier is Q2582531. VIAF identifies the subject as 165609885. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2010, 1920, 1951 and 1957.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
