Why the Swordfish sank so much Axis shipping

Is it true that the Swordfish sank more Axis shipping tonnage than any other Allied aircraft type?

Yes is the position taken, supported by long service and repeated access to merchant targets, but the cited book tables and comparative totals are not produced.

Clarke affirms the claim that Swordfish sank more Axis shipping tonnage than any other Allied aircraft type, referring to comparison tables in a book that he cannot produce during the answer. The explanation centers on service throughout the war and repeated attacks on merchant convoys off Norway and France and in the Mediterranean. Dauntless and Helldiver are suggested as probable leading alternatives, without numerical totals. When another participant attributes the contrast to Avengers flying antisubmarine patrols, he corrects that explanation: Swordfish also flew those patrols, while Avengers carried out fleet-carrier duties. In the Pacific, much of the destruction of Japanese merchant shipping came from American submarines. Service duration and target opportunities support the claimed pattern, but the requested tonnage comparison remains unavailable.
