"furious" joined the home fleet off the coast of norway on 10 april 1940 with only eighteen swordfish from 816 and 818 squadrons embarked; no fighters were able to join the ship in time. sixteen swordfish made unsuccessful torpedo attacks on german ships in trondheim harbour the following morning. on 12 april, both squadrons attempted to attack german ships in narvik in bad weather. disappointed with the failure of the torpedo attacks the previous day, bombs were carried instead. 818 squadron, making the first attack, damaged several captured norwegian ships, but lost two aircraft to flak, although the crews were rescued by the british cruiser and the destroyer . following 40 minutes behind, 816 squadron was forced to turn back by heavy weather. one aircraft was lost while landing, but the crew was recovered. another attack was launched the next day in support of the british ships entering narvik, but they contributed little and another pair of swordfish were shot down.
