units
- 720/01 Helgoland (1966-2002)
After the commissioning on March 8, 1966, the Helgoland belonged to the 2nd supply squadron (from April 1997, Trossgeschwader ) and was stationed at the Wilhelmshaven naval base . She was decommissioned on December 19, 1997 and sold to the Uruguayan Navy in 1998 . There the ship is used as ROU 22 Oyarvide .
- 720/02 Fehmarn (since 1967)
The Fehmarn was put into service on February 1, 1967 and initially also belonged to the 2nd supply squadron. With the decommissioning on September 12, 1968 taken over by the reserve flotilla, the Fehmarn was reactivated on July 15, 1969 for the 1st supply squadron and was then mainly used as a security ship for the submarine training group .
After the submarine teaching group was dissolved, the home port moved from Neustadt in Holstein to Olpenitz in 1989 and the Fehmarn has been stationed in Kiel since November 2005 . Since April 1997 she has been subordinate to the supply squadron .
Although commissioned as the second unit, the German Navy today, presumably because only the Fehmarn is in service, designates the two ships as Fehmarn- class (720).
