Fairey Swordfish, part seven

During the Norwegian Campaign, the first combat usage of the Swordfish occurred. It was on 11th April 1940 when many Swordfish aircraft were launched from HMS Furious (47) to perform an attack on German vessels that were reported to be in anchor at the port of Trondheim. When the group arrived at Trondheim, they only found two destroyers there. In the ensuing attack only one hit was recorded as being attained, but, that attack holds the record of being the first torpedo-attack of the war to performed by a torpedo-carrying aircraft.
Later, on 13th April, a Swordfish launched from HMS Warspite (03) spotted fall of shot and radioed gunnery corrections back to the ship during the Second Battle of Narvik. The total number of German destroyers sunk or scuttled during that campaign was nine. One of them was damaged by a bomb dropped from a Swordfish belonging to the HMS Warspite, at the cost of zero losses in the British side. The German submarine U-64 was also spotted by a Swordfish, which performed a dive-bombing attack upon it, scoring a direct hit and quickly sinking the submarine, making it the first U-Boat sunk by the Fleet Air Arm (FAA) in the war.
After the Second Battle of Narvik, the Swordfish continually attacked targets in the surroundings for two weeks bombing either ships, land facilities or even enemy parked aircraft. During this time anti-submarine patrols and aerial reconnaissance missions were also flown in spite of the challenge that the challenging terrain and inhospitable weather imposed, which was made worse by its open cockpit.
For many Swordfish crews the Norwegian Campaign were their first active combat missions and often involved many other 'first time tasks' like night-landings upon aircraft carriers.
