That is right, she is most probably on trials.

She is flying the flag of the german merchant navy at the stern, not the flag of the "Reichsmarine" which has a black "iron cross" in the center. A commissioned warship would show that flag.

Best regards,

Thank you all for the verification. According to Wikipedia she was delivered on April 1st, 1933, but the photo was actually made in February. Might be she was on trials to the North Sea.

Yes, without a shadow of a doubt the "Deutschland", later renamed "Lützow" as heizer says (propaganda issue, no ship named "Deutschland (german name of Germany) should be in danger of beeing sunk by the allies).

Her bridge structure differs significantly from that of her younger sister ships.

Best regards,

Michael.

1939 renamed "lützow"
