ORP Bielik, formerly HNoMS Svenner (S309), was one of four Kobben-class submarines in service with the Polish Navy.

The vessel and its sister ships were built in the period 1964–1967 by Rheinstahl Nordseewerke GmbH in Emden, West Germany for the Royal Norwegian Navy.

Before entering active Polish service the boat was modified in Gdańsk.

She was decommissioned in December 2021 alongside her sister Sęp, with the decommissioning marking the end of active service for the Kobben-class submarines.
