• , an M-class destroyer (formerly HMS Myrmidon) transferred to the free Polish Navy based in Britain in December 1942. She was sunk by U-378 on 8 October 1943 in the Barents Sea.
• , an built in the German Democratic Republic for its navy and originally named Project 660. After German reunification the unfinished hulls were bought by the Polish Navy and completed by Northern Shipyard in Gdańsk. Orkan is currently serving.
