Project 50 UD-1

Project 50, also known as UD-1, was a German First World War proposal for a very large submarine cruiser using steam machinery for high surface speed. The design sought a vessel capable of operating more like a surface raider while retaining the ability to submerge. Reports disagree over whether construction began, but no boat was completed or entered service. Its projected size and complex propulsion arrangements make it an important example of ambitious wartime submarine studies, rather than an operational U-boat class that fought the Allied blockade.

Steam propulsion promised surface performance but complicated the transition to submerged operation. Similar ambitions elsewhere demonstrated that combining the characteristics of a cruiser and a submarine created demanding technical and operational trade-offs.
