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. On R301 class 2 533mm TT were installed, and this series originally signed as GR (Geleit Räumboot), but boats had usual R- designations.

Modernizations

None.

Naval service

R301 and R306 were sunk by Allied aircraft. R304 was stricken by Allied mine.
