The PWS-19 was constructed in 1930 in order to replace the French-designed bombers Potez 25 and Breguet 19 in the Polish Air Force. It was a development of the PWS-17, which remained unbuilt. Main designers were Zbysław Ciołkosz and Antoni Uszacki. It was planned to be produced in two variants: reconnaissance PWS-19A2 and bomber PWS-19B2. It was a conventional design, a strutted high-wing monoplane with quite elegant silhouette, open cockpits and fixed landing gear. It was fitted with double tailfins to obtain a good field of defense fire.
In 1934 Antoni Uszacki designed a smaller plane basing on the PWS-19, designated PWS U-6, with G-1620 Mors 400 hp engine. It participated in a contest for an army cooperation plane, but lost against RWD-14 Czapla and was not built.
The only prototype first flew in Biała Podlaska in September 1931. During tests it showed quite good flight characteristics, although the rudders had to be enlarged to improve manoeuvrability and stability. However, on March 17, in 1933, the wings distorted in a dive and the prototype crashed (killing an observer). The Air Force considered ordering the PWS-19A2 powered by a Bristol Pegasus engine, but at the same time, a more modern aircraft the PZL.23 Karaś had been developed by PZL - a low-wing monoplane of all-metal construction. As a result, works upon the PWS-19 stopped.
Mixed construction high-wing (parasol) monoplane. A fuselage of a steel frame, covered with duralumin in front section and canvas in mid and rear sections. Two-spar wings, of wooden construction, plywood covered. Stabilizers, rudder and elevator of metal construction, canvas covered. Twin vertical tailfins. Crew of two (pilot and observer/gunner) in open individual cockpits. Conventional fixed landing gear, with a rear skid. The plane was fitted with RKL/D radio and camera.
Engine: 9 cylinder air-cooled radial Pratt & Whitney Hornet T2 in front, with a Townend ring (there were optional Bristol Jupiter VII or Bristol Pegasus). Two-blade metal propeller of a fixed pitch. Fuel tank 420 L in a fuselage, dropped in emergency.
Armament: single fixed front-mounted 7.7 mm Vickers machinegun with an interrupter gear, in the right fuselage side, single 7.7mm Vickers on a ring mounting of the observer. Up to 250 kg bombs (maximum bomb size - up to 50 kg).
