The final of the naval Furies had been the FJ-4. Many people argue that the FJ-4 was the greatest form of the complete F-86 Sabre/FJ Fury show. The FJ-4 at first glance is apparently a modified F-86 Sabre that had first flown back in 1947. But when one looks closer, it has numerous differences and only your family ancestry is obvious. The FJ-4 started its life in June 1953 as company project NA-208 which called for two prototypes and as company task NA-209 which was the manufacturing version. The Navy desired a maximum speed of Mach 0.95 and a combat altitude of 49,000 legs, needs nothing you've seen prior having been met without needing an afterburning motor.
