The keel of the German battleship Bismarck was laid down on the 1st of July 1936 at the Blohm & Voss shipyard in Hamburg. The vessel displaced 42,000 tons as built and reached 57,000 tons when fully loaded.
Hood disappeared in only eight minutes after a single 38 cm armour-piercing shell from the German battleship Bismarck penetrated her thin deck armour and detonated 70 tons of cordite propellant in her rear ammunition magazine. All but three of her crew of 1,419 men perished in the explosion.
A second torpedo struck the stern of the German battleship Bismarck near the port rudder shaft causing coupling damage that locked the rudder in a 12 degree turn to port. This jammed steering forced the ship into large circles while it steamed unable to escape pursuing forces.
The German battleship Bismarck disappeared beneath the surface at 10:40 on the 26th of May 1941 after scuttling charges detonated around 10:20. The wreck was later discovered on the 8th of June 1989 by Robert Ballard resting on the keel at a depth of approximately 4,790 meters.
Out of over 2,200 men aboard the German battleship Bismarck only 114 survived the sinking. Rescue efforts included 85 men picked up by the cruiser Dorsetshire and 25 men taken off by the destroyer Maori before other vessels arrived to recover additional survivors.
