That’s kind of a major research project however at Taranto torpedo and dive bombers were split 11:10
That was one of my biggest problems with the attack (which was brilliant..but) the attacking force had far too few torpedo carrying aircraft for the job in hand
Given that on 8th July 1940 it took 6 attacking aircraft from HMS Hermes attacking the
Richelieu at Dakar to get 1 torpedo hit - I am not sure why 11 torpedo armed aircraft could be expected to get more than 2 hits in total on the 5 targeted Italian Battleships.
Surely the prize was the Littorio and Vittorio Veneto and possible the 3 heavy Crusiers in the outer harbour - with bonus points for the rebuilt battleships
So ether more torpedo carrying aircraft (more aircraft!) which implies 1 or more extra carriers involved or those 11 aircraft exclusively targeting the Littorio and Vittorio Veneto.
If another aircraft carrier was used such as Ark Royal (instead of conducting Operation Crack the attack on Cagliari at the same time) - her Skuas could have been the Flare carriers - along with a secondary role of bombing the Heavy crusiers while her Swordfish (which I understand to be 28 at the time) and those other 10 From Illustrious 21 Swordfish now all carrying torpedoes would allow 49 torpedo bombers to take part in the attack.
Make sure that Littorio and Vittorio Veneto each get 12 each from the best 2 squadrons (to ensure at least 2 hits on each ship) and then split up the rest of the attacking force (25 Aircraft) among the remaining Battleships.
Then get RAF aircraft to do a bit of 'gardening' (air dropped mines) outside of the harbour to hopefully catch any ships that try to 'flee' the next morning
But I digress
