Since 1928 we have been pioneers of Polish aerospace.

Engineering services


The desing team of PZL Warszawa Okęcie has many years of experience in aircrafts designing, testing, certification, production support and aircraft operation support. Its traditions date back to the 1930s, beginning with the implementation of fighter aircraft designs with the Puławski PZL P-1 wing and its developmental versions P7, P11, P24

After the Second World War, training planes became the specialty of PZL Warszawa-Okęcie

Their continuation is currently being developed the family of training aircraft ORLIK

The second family is the multi-purpose PZL-104 Wilga

The last group are agricultural airplanes PZL-106 Kruk

Since 1928, PZL Warszawa-Okęcie has sold over 6,000 aircraft of 40 different types to more than 30 countries
