The Kriegsmarine was one of three official branches, along with the Heer and the Luftwaffe of the Wehrmacht, the German armed forces from 1933 to 1945.

Scuttling is the deliberate sinking of a ship by allowing water to flow into the hull. This can be achieved in several ways—seacocks or hatches can be opened to the sea, or holes may be ripped into the hull with brute force or with explosives. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self-destruction to prevent the ship from being captured by an enemy force ; as a blockship to restrict navigation through a channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers.
