The Lublin R-XIII was the Polish army cooperation plane, designed in the early-1930s in the Plage i Laśkiewicz factory in Lublin. Since 1927, they started working on their own prototypes. Those were designed by J. Rudlicki and his team of more than a dozen people including engineers Marian Bartolewski, Jerzy Dąbrowski, Antoni Uszacki, Janusz Lange, Jerzy Teisseyre, Witold Grabowski, Jaworski and others.

 

The factory’s first own product was a reconnaissance bomber Lublin R-VIII built in 1928. Its airliner variant, the R-IX, was constructed in a short while. In 1930, they produced a pilot series of 5 Lublin R-VIIIs, 3 of which were converted to seaplanes in 1932. At the beginning of 1929, they performed a test flight of a liaison aircraft prototype designated R-X; a pilot series composed of 5 examples was built in 1931. Prototypes of the Lublin R-IX airliner (1929) and Lublin R-XI airliner (1930) as well as its improved variant, the R-XVI, failed to meet the requirements of LOT Polish Airlines so the production was not started. However, 5 examples of an air ambulance variant R-XVI were built in 1933-1934. In 1931, they created the R-XII sport aircraft that was not put to use.
