https://en.wikipedia.org/wiki/North_American_FJ-4_Fury
The North American FJ-4 Fury was a swept-wing carrier-capable fighter-bomber for
the United States Navy and Marine Corps. The final development in a lineage that
included the Air Force's F-86 Sabre, the FJ-4 shared its general layout and
engine with the earlier FJ-3, but featured an entirely new wing design and was a
vastly different design in its final embodiment.
Compared to that of the FJ-3, the FJ-4's new wing was much thinner, with a six
percent thickness-to-chord ratio, and featured skin panels milled from solid
alloy plates. It also had an increased area, and tapered more sharply towards
the tips. Slight camber behind the leading edge improved low speed
characteristics. The main landing gear design had to be considerably modified to
fold wheel and strut within the contours of the new wing. The track of the main
wheels was increased and because they were closer to the center of gravity,
there was less weight on the nosewheel. Wing folding was limited to the outer
wing panels.
The FJ-4 was intended as an all-weather interceptor, a role that required
considerable range on internal fuel. The FJ-4 had 50% more fuel capacity than
the FJ-3 and was lightened by omitting armor and reducing ammunition capacity.
The new wing was "wet"; that is, it provided for integral fuel tankage. The
fuselage was deepened to add more fuel, and had a distinctive "razorback" rear
deck. A modified cockpit made the pilot more comfortable during the longer
missions. The tail surfaces were also extensively modified and had a thinner
profile. The overall changes resulted in an aircraft that had little in common
with the earlier models, although a family resemblance was still present. The
two prototypes had the same Wright J65-W-4 engine as the FJ-3, but production
aircraft had the J65-W-16A of 7,700 lbf (34 kN) thrust.
The first FJ-4 flew on 28 October 1954 and delivery began in February 1955.

The Navy ordered six FJ-4s to be converted to FJ-4F to test rocket engines, but
only two were completed. These featured the North American Rocketdyne AR-1
engine, installed in a fairing above the tail pipe of the jet engine. It ran on
hydrogen peroxide and JP-4 jet fuel, and provided an additional 5,000 lbf (22
kN) of thrust for short periods. The FJ-4F reached speeds of Mach 1.41 and
altitude of 71,000 ft (21,600 m).
With the new designation system adopted in 1962, the FJ-4 became the F-1E and
the FJ-4B the AF-1E. AF-1Es served with United States Naval Reserve units until
the late 1960s. A total of 1,115 Furies were received by the Navy and Marine
Corps over the course of its production life.
