The design that led to the TBF wasn't even requested by the USN until 1939 with prototype contracts awarded in April 1940. Production didn't start until 1942.
Douglas only built 130 TBD between 1937 and 1939 for the USN. Does it really represent a huge improvement in performance over the Swordfish?
