If 500 Brewster Bermudas were exchanged for a better aircraft, what should replace them?
Short answerThere is no single answer until the mission is specified: Vultee Vengeances suit ground attack, Dauntlesses suit scout bombing, and simpler light aircraft suit towing or utility work.
NotesThe answer refuses to treat 'better' as a complete requirement. For the ground-attack role under discussion, the Vultee Vengeance is offered as a successful contemporary alternative. If the intended mission is American-style scout bombing, the Dauntless is the more direct comparison. Target towing does not require a bomber's full crew and structure, while utility transport could be handled by a much simpler light aircraft. The exchange turns a paper aircraft swap into a lesson in defining the operational role before selecting equipment.
