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

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

Some boats were commissioned again by West German navy in 1956 as follows:

6/1956, Orion, Capella, Merkur, Rigel, Mars, Castor, Pollux, Sirius; 7.1956, Regulus, Spica, Jupiter, Saturn; 12.1956, UW5 were recommissioned with data as given in the table

Naval service

R131, R139 and R141 were sunk by Allied aircraft. R145 was torpedoed by Soviet aircraft.
