 One of them, and the best known today, was an offensive operational plan codenamed Burza (Thunderstorm), that assumed independent search of targets, free maneuvering and attacking enemy ships and transports between Świnoujście () and East Prussia.In consideration and planning was also plan of actions on the sea routes between harbors of Germany and Swedish port Luleå

As a result, Polish submarines deployed along Polish coast, in proximity to their own naval base, were deprived of chances to find targets – while they were exposed there to operations of German air and light naval antisubmarine units.Therefore, although no Polish submarine was sunk in this stage of war, the operation had no discernible impact on the September campaign.
