By 03:50 on 13 February, the ship had reached Helgoland. Scharnhorsts deployment to Norway In January 1943, it was decided to deploy Scharnhorst to Norway, along with Prinz Eugen and several destroyers. Attempts to sail on 7 and 23 January were aborted after the navy received reports of heavy activity at British air bases in Britain. A third try on 10 February terminated when Scharnhorst ran aground while trying to avoid collision with a U-boat. Repairs lasted until 26 February. On 8 March, Scharnhorst and four destroyers departed Gotenhafen; she arrived off Narvik on 14 March. For 6 months, fuel shortages curtailed any major operations by Scharnhorst or the other ships in Norway, which included the battleship and the heavy cruiser . On 25 November 1943 Scharnhorst carried out a two-hour full-power trial, achieving , and it was noted that her draught had increased by over from her 1940 trials, where she had attained .

Belfast picked up Scharnhorst on radar at 08:40; forty minutes later lookouts on Sheffield spotted the ship, at a distance of . Shortly thereafter, Belfast fired star shells to illuminate the target, and Norfolk opened fire with her 20.3 cm (8 in) guns; in the span of 20 minutes, she hit Scharnhorst twice. The second hit destroyed Scharnhorsts forward Seetakt radar. By 10:00, Scharnhorst, using her 4–6 knot speed advantage, broke off the engagement and resumed searching for the convoy. At 12:00, Belfast again picked up
