Would one hundred Brewster Buffalo fighters help the Royal Navy in 1939?
Short answerYes; they could serve as an adequate interim naval fighter until 1941 despite the type's later reputation.
NotesThe Buffalo defeated the first Wildcat version in competition, complicating its later reputation as a uniformly poor fighter. Its shortcomings were clear by 1941, but that does not make it useless in 1939. A hundred navalised examples could have given the Fleet Air Arm a competent single-seat fighter while newer aircraft developed. The value of the proposal lies in filling a two-year gap rather than keeping the Buffalo in front-line service indefinitely.
