The Swordfish was NOT a WW1 Biplane.
Now, raiding Bismarck, they scored another hit, but the belt armor held, - so no damage.
The Prime time of the Swordfish was when attacking the Italian Navy at Taranto, scoring hits on 3 major Italian ships, putting them out of action for a long time. Only 2 planes were lost.
Although slow and out-dated, the Swordfish did its job. It was a very sturdy airplane, and had good handling which helped a lot under tough cirkumstances in carrier operations.
Swordfish to AH? One day, but it'll be a while.
