Convoy RS 3 was a South Atlantic convoy which ran during the height of the Battle of the Atlantic in World War II. It was a small coastal convoy going from Rabat to Sierra Leone. The convoy lost its three biggest ships to U-boat attacks in March 1943, which contributed to the fact that in March 1943 most of the ships sunk by U-boats were lost in convoys. As convoying was the key answer to the U-boat threat, this led to a temporary crisis in Allied shipping.
