The new buildings were commissioned to replace older units from the Lauenburger Hitzler shipyard . They should be able to break ice up to 35 centimeters thick and ensure shipping in the Port of Hamburg even in winter. In the ice-free period, they can also be used as port tugs and for transport tasks. The icebreakers are powered by a MAN 2842LE412 diesel engine , which operates with 588 kW on a four-blade fixed propeller.

The first two ships, Christian Nehls and Johann Reinke , arrived in the Port of Hamburg on December 15, 2015 and were officially put into service on January 22, 2016.
The Christian Nehls was christened by Anke Harnack and named after Christian Nehls , a former hydraulic engineering director in Hamburg. The ship replaces the tug of the same name built in 1955.
The godmother of Johann Reinke is Karin Chrappek, an employee of the Hamburg Port Authority. The ship is named after Johann Theodor Reinke (1749–1825), a former Hamburg electricity and sewer construction director. The Johann Reinke replaces Hafenbau 2, built in 1961 .
The icebreakers still under construction will be named Hugo Lentz and Johannes Dalmann .
