The PWS-19 was a Polish reconnaissance and bomber aircraft prototype of the 1930s.
Only one prototype was built.
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.
Mixed construction high-wing (parasol) monoplane.
