The Eisvogel was in service for the Naval Base Command Kiel and sold to private owners after decommissioning. Since 2010 she is operated as a civil tugboat in Trieste. The Eisbär was based along the German North Sea coast. After decommissioning she was laid up in Wilhelmshaven later sold to the Netherlands for scrapping.
