Her engine was then rated at 115 nhp.[4] In 1934, her Code Letters were changed to DHBR.[5]
In September 1939, Preußen was requisitioned by the Kriegsmarine, initially serving in the Baltic Sea as VorpostenbootV 1101 Preußen with 11 Vorpostenflotille, which was under the command of Kapitänleutnant der Reserve Günther Reisen. From January 1940, she served in the North Sea.[1][6] On 14 March 1940, she found part of a torpedo from U-54, which had been missing since 20 February, presumed to have been sunk by a mine with the loss of all 41 of her crew.[7] On 5 June 1940, the cargo shipPalime struck a mine off Stavanger, Norway and was beached.
