The original project was prepared by the German Democratic Republic for its navy and was named Project 660 ("Sassnitz class" in NATO code[3]). After the Unification of Germany the unfinished hulls were bought by the Polish Navy from VEB Peenewerft shipyard in Wolgast and successfully completed in Northern Shipyard in Gdańsk.[2]

After its completion in 1994 the ship was incorporated into the 31st Rocket Warships Squadron, 3rd Ship Flotilla.
