R-boats appeared from the Baltic and Black Sea to the Mediterranean, Arctic, North Sea, and Atlantic Wall in minesweeping, patrol, and convoy roles. Their utility outlasted the Third Reich: postwar Bundesmarine craft drew on the wartime R-41 design.

The Treaty of Versailles compounded a pre-existing disparity by constraining Germany's ability to rebuild the breadth of shipbuilding infrastructure needed for rapid adaptation.
