Why do German- and English-language sources attribute the first Deutschland-class ship to different builders?
Short answerThe disagreement appears to reflect whether a source names the company awarded the contract or the subsidiary yard that physically built the ship.
NotesThe answer distinguishes the contracting company from the subsidiary yard where construction occurred. English-language accounts tend to follow the corporate award, while German accounts emphasize the physical building site. This remains an unresolved attribution problem requiring more yard-history research, rather than proof that one language tradition is simply wrong.
