From 1923 to 1937 Boeing produced a series
of excellent fighters for the Army and Navy,
the last of which was the F4B-4. In 1927
Boeing produced models 83 and 89, designated
F4B (Navy) and P-12 (Army), first flown in
June and August 1928, respectively. The two
models differed in landing gear design, one
for carrier operation, the other to
accommodate a centerline bomb rack. Highly
successful, the F4B-4 was the Navy's
first-line fighter from 1932 to 1937. The
Museum's aircraft was delivered as a P-12E
and modified during restoration to the F4B-4
configuration.
Though best known in later years for
producing large bomber or transport
aircraft, Boeing produced a series of
excellent fighters from 1923 to 1933. The
most famous of those biplane fighters, the
F4B, was the refinement of design experience
gained from its FB, F2B and F3B
predecessors.
The Model 100 series, designated XF4B-1 by
the Navy and XP-12 by the Army, differed
only slightly in design; the Navy version
was built for carrier operation (Model 83),
while the Army version (Model 89)
incorporated a centerline bomb rack and
split axle landing gear. The two prototypes
flew in June and August 1928, respectively.
By May 1929 the F4B-1 had also adopted the
split axle landing gear and bomb provision,
along with a tailhook for carrier landings.
Deliveries were made to the Navy between
June and August 1929. While in service,
F4B-1s underwent a number of changes.
Individual fairings behind each cylinder
were removed, and ring cowlings and modified
fins replaced the original type. By 1932,
the F4B-2 incorporated the ring cowling,
Frise ailerons, spreader-bar axle and a tail
wheel for carrier mobility. Delivered
between January and May 1931, 46 F4B-2s were
assigned to Fighting Squadron (VF) 6B aboard
USS
Saratoga (CV-3) and VF-5B aboard
Lexington (CV-2). In April 1931,
the Navy ordered 21 F4B-3s, delivered in
December 1931 and January 1932. By July 1932
deliveries of the F4B-4 commenced, with 92
aircraft delivered by February 1933, the
last 45 of which incorporated a raised
headrest. At the same time, 21 of the new
aircraft were delivered to the Marine Corps.
Nimble, rugged and reliable, the F4B-4's debut coincided nicely with advances in carrier operations aboard the new carriers Lexington (CV-2) and Saratoga (CV-3). The aircraft remained the Navy and Marine Corps' first-line fighter until replaced by faster and more powerful Grumman biplanes. From 1937 to mid-1941, the F4B-4 was assigned to training command duties, Pensacola's Squadron Five employing the F4B-4 in the last phase of pilot training. |
