GRUMMAN’S F4F-3 WILDCAT PART ONE
By: Thomas McKelvey Cleaver
The F4F-3 was the outcome of a develop-
ment process by Grumman in response to
a 1938 U.S. Navy requirement for a repla-
cement for the F3F biplane fighters. The
Navy was conservative in its planning;
while the Brewster Aircraft Co. would
create a monoplane, the XF2A-1, Grumman
was asked to create another biplane figh-
ter, the XF4F-1. Grumman convinced the
Navy that, with a few modifications, the
F3F-2 could meet the requirements of the
XF4F-1; this became the F3F-3, and Gru-
mman was able to proceed with its own
monoplane design, the XF4F-2.
How it was that the XF4-2, designed and
built by the Navy‘s premier fighter design
company, lost out to the XF2A-1, the first
aircraft design by a company primarily
known for building horse drawn buggies
during the 19th century, with no experien-
ce of aircraft production, is a bureaucra-
tic mystery that has never been fully ex-
plained. Luckily for the Navy and history,
Grumman convinced the Bureau of Aero-
nautics to allow them to rework the design
a third time, resulting in the XF4F-3. It had
marginally better performance than the
F2A 1, which had just entered production;
Brewster was already demonstrating its
inability to meet production schedules,
and the Navy was glad to be able to or-
der the new fighter from the more reliable
company.
The first production F4F-3 flew in Februa-
ry 1940, powered by a Pratt and Whitney
R-1830-76 Twin Wasp with a two stage
supercharger, with the second following
that July. In April 1940, due to fears of
production delays with the two stage su-
percharger, the Navy asked Grumman to
change the airplane to use the R-1830-90
Twin Wasp with single stage superchar-
ger. This became the F4F-3A, 55 of which
were given to the Marines in 1941, when
they did not have the necessary high al-
titude performance with the single stage
supercharger. The last 100 F4F-3s were
powered by the R-1830-86 Twin Wasp with
a two stage supercharger; these were vi-
sually indentifiable from the early F4F-3s
and F4F-3As by the absence of an intake
on the upper cowling, that having been
moved inside the cowl, and the presence
of additional cowling flaps. (A further 100
F4F-3s, which were produced in 1942 for
the “Wildcatfish” floatplane fighter, were
used as trainers following cancellation of
that program.)
VF-41 was the first to equip with the F4F-
3, arriving aboard USS Ranger (CV-4)
on 4 December 1940. VF-42 aboard USS
Yorktown (CV-5) quickly followed along
with VF-71 and VF-72 aboard USS Wasp
(CV-7) in February 1941. VF-6 on USS En-
terprise (CV-6) re-equipped with F4F-3s
F4F-3 of VF-6 on hangar deck of USS Enter-
prise (CV-6), fall 1941.
