In 1940 during the German occupation of Norway the Kriegsmarine took over two merchant ship building at the Moss shipyard. The two ships Rio X and Rio Y were completed as motherships for small 11m mine disposal boats, and were used to clear mines for U-Boats and other warships from the Norwegian coastal waters as well as the Baltic.
MRS-25 was mines and sunk while MRS-26 was completed only in 1944 and was used in 1945 as transport to evacuate troops and civilians fleeing the Russian advance. As such, the ship was attacked by Russian bombers, and on the first attack the ship managed to shoot down two bombers with no damage, but a second attack resulted in the sinking of the ship.
