The Lütje Hörn class consisted of eight port tugs of class 723, which were in service for the German Navy from 1958 to 1990 . Four tugs were then used by the Greek Navy .
From 1986 the units were gradually decommissioned and replaced by the Nordstrand class . With the exception of Mellum and Trischen , the ship names of the Lütje-Hörn class were taken over from the new and larger harbor tugs. The units handed over to the Greek Navy were transferred to Greece in 1991 with the dock ship Condock III .
