In 1938 the USN ordered an improved version of the F3F-2 because the replacement
monoplane Brewster F2A and F4F Wildcat were delayed in development. To accomplish
this Grumman started to modify the 65th F3F-2 to F3F-3 standards with 26 more aircraft
being produced as F3F-3. The modifications were comprised of an upgraded engine
with a smaller diameter propeller and a modified cowling as well as small flaps and
revised leading edges. The armament wasn’t changed. By the end of 1941 the entire
operational biplane fleet was replaced but 117 were sent to various bases for training
and transportation. The F3F-3 had two distinctions; it was the last of the USN biplanes
as well as being the fastest carrier-borne biplane in the world.

During 1938 – 1939 VF-5 received twenty seven Grumman F3F-3 fighters while serving
on the USS Yorktown CV-5. These aircraft had BuNos. 1444-1470. In 1940 the F3F-3s
were being replaced in fighter squadrons by the mono-wing Brewster F2A Buffalo and
by the time of the attack on Pearl Harbor the 180 or so remaining F3F-3s were only
being used to ferry personnel at NASs or as training aircraft. The Grumman F3F would
be the last biplane fighters ordered by the U.S. military.
