ID card - Kriegsmarinewerft Wilhelmshaven.
With the start of the war in 1939, the shipyard's activities shifted. The construction of capital ships that had already begun or was planned was stopped, and activities were subsequently limited to the construction of smaller war vehicles and submarines as well as repair work and repairing battle damage to ships.
As a major manufacturing facility for the defense industry, the shipyard was bombed over a hundred times, causing extensive damage. However, the shipyard always remained in operation. Many civilians died in the air raids.
