After her decommissioning the German Navy decided to convert her into a training and support vessel for mine-clearing divers. The rebuilding was done at the Peene-Werft shipyard in Wolgast and on April 6, 1995 she was recommissioned as Mühlhausen (M1052) and classified as Type 742A ship.
After forty years in service, the Mühlhausen was decommissioned in 2007 and was replaced by the converted Frankenthal-class minehunter Rottweil.
At the time of her decommissioning, Mühlhausen was the largest naval ship still in service with a hull made of glued laminated timber (mahogany).
