[2] On 20 October she joined an escort group of nine destroyers, a Norwegian corvette and two minesweepers which sailed to the Kola Inlet as part of Operation FR, tasked to bring back merchant ships that had been waiting in Russian ports over the summer while the Arctic Convoys were suspended.

[4] She returned to Scapa Flow, but was out again on 10 December to screen the battleship Duke of York and cruiser Jamaica which had been ordered to sea to cover Convoy JW 55A.

During the action Duke of York hit Scharnhorst's starboard boiler room with a 14-inch shell, slowing her briefly to 10 knots (19 km/h; 12 mph) as she attempted to evade the British fleet.

Closing from astern, Saumarez and Savage fired star-shells, blinding the Germans to the approach of Scorpion and the Norwegian Stord on the starboard side of the battleship.

She crossed the channel on 5 June and took up position off Ouistreham to bombard targets in support of Allied landing forces in the Queen Sector of Sword Beach.

[10] On 7 June she was assigned to patrol the Eastern Task Force area following the loss of her sister ship, the Norwegian Svenner to German T-boats.

[11] In October she was diverted to support Operation Lycidas, screening two escort carriers, Fencer and Trumpeter, as they carried out aerial minelaying around the Norwegian coast.

[2] She escorted Convoy JW 63 over the New Year period, her anti-aircraft gunners accidentally shooting at (and missing) two Wildcats which had been launched to intercept a German aircraft.
