Project history

Motor minesweeping boats, or R-boats (Räumboote) were developed for shallow water areas, but actually became multi-purpose ships for operations in inshore waters; besides the basic purpose, they were used as patrol, anti-submarine and rescue ships. The prototype was created by F.Lürssen on the basis of F type minesweeping boat of WWI period.

All had composite hulls. Usage of minesweeping gear was supposed at heaving to 6 on the Beaufort scale.

Modernizations

1943 - 1944, most survived: + 1 x 1 - 37/80 SK C/30 or 1 x 1 - 37/69 FlaK M/42, 2 x 2 - 20/65 C/38, DCR
