PZL P.11

The PZL P.11 was a Polish fighter aircraft, designed in the early 1930s by PZL in Warsaw. It was briefly the most advanced fighter aircraft of its kind in the world. The PZL P.11 served as Poland's primary fighter defence in the Polish campaign of 1939, but with the rapid advances in aircraft design in the late 1930s (seen in such fighters as the Messerschmitt Bf 109), it proved outclassed by its rivals at the onset of the war.

Design and development

The history of the PZL P.11 started in 1929, when a talented designer, Zygmunt Puławski, developed an all-metal, metal-covered monoplane fighter. While most of the world's forces were still using biplanes, the new P.1 used a high-mounted gull wing to give the pilot an excellent view. A second prototype, the P.6, was completed the next year. The design generated intense interest around the world, the layout becoming known as the "Polish wing" or "Puławski wing". A further improvement, the PZL P.7, was built for the Polish Air Force in a series of 150.
