At dawn, 0243 hours, 15 British Fleet Air Arm Skua aircraft from HMS Ark Royal dive bombed German battleships Scharnhorst and Gneisenau at Trondheim, Norway. Scharnhorst was hit by a 500-pound bomb, but it failed to explode. 8 Skua aircraft were shot down; 6 airmen were killed and 10 were taken prisoner. The remaining 7 aircraft returned to Ark Royal at 0345 hours. Nearby, Ark Royal's escorting destroyers HMS Antelope and HMS Electra collided in fog; both sustained damage that would take them out of action until Aug 1940.
