RWD 22
RWD 22 was a Polish twin-engine torpedo bomber and naval reconnaissance floatplane design. Developed by Leszek Dulęba and Andrzej Anczutin of Doświadczalne Warsztaty Lotnicze ("Experimental Aeronautical Workshops", DWL) in 1939, the project was to be developed under the brand of the RWD design bureau. The outbreak of World War II interrupted the design and it never left the planning stage. Design and development. In late 1930s the Polish Navy sought a replacement for the ageing R-XIIIter and Lublin R-VIII. The new design was to replace those aircraft in both the torpedo bomber and close-range  reconnaissance roles. Design of the RWD 22 started in October 1938 and by January 1939 the basic three projects were ready, each with different engine and armament configuration, but with a similar silhouette. The first version was to be equipped with a German-built Argus As-10c with of power and would carry up to of bombs. The second variant was equipped with second generation Walter Minor 12-JMR with a projected power of and was to carry of bombs. The third and final version was to be equipped with a Polish-built third generation PZL G-1620B Mors II engine, already  being used with the RWD-14 Czapla. Alternatively, American Pratt & Whitney R-985 Wasp Junior SB could also be used. A land-based version of the aircraft was also being considered under a separate designation RWD 24. It was most likely to receive two Gnome-Rhône 14M Mars engines of . In the summer of 1939 the third, heaviest variant was chosen by the Polish Navy and a wooden mock-up was completed for aerodynamic trials. The designers also received 150.000 Polish złoty for the prototype, which was to be completed by mid-1940. The first serial run was to be started in  1940 and by early 1942 the Naval Air Squadron was to receive the first 12 planes. However, the Nazi and Soviet invasion of Poland and the outbreak of World War II interrupted further works.
