What if the Barracuda had entered service in 1941?

The counterfactual gives the Royal Navy a fast, capable dive and torpedo bomber in 1941 rather than 1943, including the Barracuda's ability to dive at 70 degrees. This date is too late to change the Taranto raid. Avoiding an eight-month delay after the X engine failed would require enough Merlin production to select and supply an appropriate replacement quickly. The Mediterranean and Operation C, the Japanese Indian Ocean raid, are identified as likely moments when a stronger carrier strike aircraft could matter. The Albacore might disappear sooner because the Barracuda would occupy its intended frontline place, while the cheap and maintainable Swordfish would remain valuable in second- and third-line roles. The closing prompt asks whether timely British adoption would influence American and Japanese carrier-aircraft development or merely improve local Royal Navy performance. This is a bounded counterfactual about procurement timing and industrial capacity rather than a claim that one aircraft would decide the war.
