Would receiving the Douglas SBD Dauntless earlier have greatly improved the Royal Navy's air arm?
Short answerA faster aircraft would still need to suit British missions and equipment; inconsistent aircraft terminology leaves the specific Douglas comparison uncertain.
NotesBritish torpedo-bombing and night-attack requirements explain why superior paper performance did not automatically make an aircraft a suitable Swordfish replacement. Taranto provides the example: the shallow-water attack system required a special airframe hardpoint for its wire, and the available position relative to a torpedo mounting is left uncertain. Swordfish and Albacore already served the Fleet Air Arm's frequent night attacks. Although the question names the SBD Dauntless, the reply moves into torpedo-aircraft terminology and does not establish that the SBD could perform those missions.
