From 1847, Schichau produced steam engines for ships, starting with the engine for the first entirely Prussian-built steamer
James Watt (built by nearby Mitzlaff shipyard). In 1854, Schichau built the shipyard at Elbing, known as the
Elbinger Dampfschiffs-Reederei F. Schichau ('Elbing Steamship Shipping Company F. Schichau'). The first ship launched was the small steamer
Borussia in 1855 – the first Prussian iron propeller ship.
Interwar years When Ziese died in 1917, the management of the company passed to the husband of his only daughter, Hildegard, the Swede Carl Carlson. After his death, Hildegard Carlson ran the firm. After World War I, the shipyard was threatened with bankruptcy and in 1929 it was bought by the German government. In 1941–1944
F. Schichau was operator of
Nobel & Lessner shipyard in German-occupied
Tallinn. ==U-boat production==
