Full length: 127.7112 m. After the defeat of Germany in World War I, the terms of the Treaty of Versailles clearly stated that the defeated Germany was not allowed to build and own a fearless battleship, only allowed to retain eight old battleships, except for training and coast. Outside the defense, no other use, these restrictions are that the German Navy can only be a regional maritime force with limited capabilities. On August 25, 1939, the old battleship of Shihe was a "friendly visit" to the free city of Danzig, Poland, in the name of "commemorating the death of soldiers in World War I." At 4:17 am on September 1, Shihe bombarded the Polish military camp. The first shot of World War II was launched, and a cannon was opened to open the curtain of World War II. In the Second World War, the German Navy surface warships basically contracted into the port, and the old Shihe also painted land camouflage to hide in Tibet. In the end, it was impossible to escape the fate of being bombed. After the war, he was salvaged as compensation for the Soviet Union.
