The PZL P.24 fighter, like the P.11, was developed from Z. Puławski’s P.6 design and intended for export. Due to licensing restrictions, export versions used Gnome-Rhône engines instead of Polish-made ones. Design work for both domestic and export models progressed simultaneously, allowing improvements such as the P.11a adopting the vertical stabilizer designed for the P.24.
After two prototypes based on the P.7, the third P.24 prototype incorporated parts from the P.11c (tail and wings), becoming the production standard. Its twin-row radial engine prevented fuselage-mounted guns, so armament was installed in the wings, with the option of two 20mm Oerlikon cannons cleverly concealed under wing fairings.
The P.24 became a major export success, sold as complete aircraft or via license to Bulgaria, Romania, Turkey, and Greece, though World War II halted further sales. The P.24G, with four machine guns, formed the backbone of the Greek Air Force during the Italian invasion of 1940 and subsequent German attack, achieving 37 Italian and 3 German kills.
Today, only one P.24 survives, displayed at the Turkish Air Force Museum in Istanbul.
