After nationalization of the bankrupt Plage i Laśkiewicz works in 1936, as the LWS, the R-XXA design was taken over as the LWS-1. However, its development was soon canceled in mid-1936, because the factory proposed a floatplane variant LWS-5 of slightly more modern LWS-6 Żubr bomber. This design was not completed as well, and the Polish Navy remained without torpedo bombers (there were finally ordered six CANT Z.506 in Italy, but only one unarmed was delivered by the outbreak of the war).
