Following a number of international training voyages, the ship was used as a stationary office ship after the outbreak of World War II and was only put into ocean-going service again in 1944 in the Baltic Sea. On 14 November 1944 she hit a Soviet mine off Sassnitz and had to be towed to port in Swinemünde. Eventually transferred to Flensburg, she was taken over there by the Allies when the war ended and finally confiscated by the United States.
