While under repair at Rosyth in August–September, four additional Oerlikons were added on the quarterdeck. In May 1943 gun shields were added to the 4.7-inch guns and the catapult on the roof of 'X' turret was removed. Many more Oerlikons were installed during this brief refit, specifically 36 more single mounts and 5 twin mounts, which gave "Rodney" a total of 67 weapons in 57 single and 5 twin mounts. In preparation for her role providing naval gunfire support during the Normandy landings, two more Oerlikons were added as was a Type 650 radio jammer in January–March 1944. These additions increased the ship's deep displacement to and her crew to 1,631–1,650 men.
