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 boats of R41 - 107 and 109 - 111 groups: + 1 x 1 - 37/80 SK C/30 or 1 x 1 - 37/69 FlaK M/42, (1 - 3) x 1 - 20/65 C/38 or (1 - 2) x 2 - 20/65 C/38

1944, some survived: + 1 x 1 - 86 R Ag M42/43 rocket launcher

Some boats were commissioned again by West German navy in 1956

10/1956, Algol, Altair, Wega; 11.1956, Aldebaran, Arkturus, Deneb, Pegasus, Skorpion; 12.1956, UW4 were commissioned with data as given in the table.

Naval service

R50, R73, R77, R78, R82, R86 and R109 were sunk by German mines. R54, R64, R74, R93, R94, R95, R110, R114, R116 and R126 were stricken by Allied mines. R60, R61 and R62 were destroyed in Helsinki by sabotage. R66 and R70 were sunk by Soviet mines. R69 and R106 were sunk by Soviet aircraft.
