A U.S. Air Force B-52H Stratofortress from the 5th Bomb Wing at Minot AFB, North Dakota, prepares to refuel from a tanker over the western United States in 2002. This venerable Cold War warrior entered service in 1955 and remains a potent weapon in the second decade of the twenty-first century.
Cold War and Modern Era
In World War II, military aeroplanes had introduced the turbine engine and the atomic bomb to the world, and combat aircraft would continue to lead the way in technological developments in the years after 1945. The superpower rivalry of the Cold War saw the limits of science pushed yet further, as aircraft designers battled to provide the ultimate combination of performance, agility, weapons and sensors. As the Cold War came to an end, stealth added another possible requirement to the designer’s remit, while in the twenty-first century network-centric warfare and precision-guided munitions are the order of the day.
North American F-86 Sabre (1949)
Perhaps the finest jet fighter of its generation, the F-86 won its spurs over Korea and went on to enjoy unprecedented success in a variety of combat roles and with dozens of different air arms around the world, serving for close to 50 years. With nearly 10,000 built, it is the most prolific Western jet fighter of all time.
Best known for its MiG-killing exploits over Korea, the F-86 was first flown in prototype form in 1947, and remained in front-line service in Bolivia as late as 1994. Originally developed to meet a USAAF specification, the design was intended to be a day fighter, albeit one that would also be capable of operating as an escort fighter or dive-bomber. The result was the North American NA-140 design.
This F-86D was flown by the ‘Geiger Tigers’ of the 520th Fighter Interceptor Squadron, Air Defense Command, based at Geiger Field, Washington, in 1955. The three stripes on the fuselage indicate this is the commander’s aircraft.
The USAF’s Sabre was evolved from an earlier, straight-wing North American jet fighter, the FJ-1 Fury that was built for the U.S. Navy. The addition of a swept wing on the F-86 ensured that it would be one of the finest dogfighters of its era, with performance that far exceeded the previous generation of jet fighters. In late 1944 North American received a contract for two XP-86 prototypes, but these were originally to be straight-winged. The acquisition of technical data from Nazi Germany after the war forced a major rethink, and the XP-86 was redrafted with swept wing and tail surfaces. The result was a year’s delay to the programme, pushing back the maiden flight to October 1947. The XP-86 as initially flown was powered by a General Electric TG-180 turbojet developing 16.68kN (3750lb) of thrust. It was re-engined in April 1948 with a General Electric J47, becoming the YP-86A, capable of exceeding Mach 1 in a shallow dive.
The initial-production P-86A version was powered by a 21.57kN (4850lb) J47-GE-1 and first took to the air in May 1948. The first recipient of the F-86A (as it had been renamed in June 1948) was the 94th Fighter Squadron of the USAF’s 1st Fighter Group at March Field, California, in February 1949. It was swiftly followed by the 4th and 81st FGs. The A-model was also the first to see combat, when the 4th FG was despatched to Japan in late 1950 for service in the Korean War. A total of 554 F-86As were completed, most being powered by the 23.13kN (5200lb) J47-GE-3, -7, -9 or -13 turbojets.

The improved F-86E, and the definitive F-86F day-fighter model also saw action in Korea, and between them Sabres were initially credited with almost 800 MiG-15s destroyed, for the loss of only around 80 of their own, to give a victory ratio of 10:1. More recent research suggests that the actual ratio was closer to 2:1. Meanwhile, of the 41 American pilots who achieved ace status during the Korean War, all but one flew the F-86. The F-86E added an all-moving tailplane, while handling was further improved in the F-86F (of which 1539 were built), which featured an extensively modified wing.
Last of the fighter line from North American production was a dedicated fighter-bomber, the F-86H, with a more powerful J73 engine contained within a much-redesigned fuselage, additional fuel capacity and nuclear-weapons capability. A total of 477 were built.
While the day fighters are the best known Sabre variants today, the most numerous member of the family was the F-86D all-weather fighter that was intended for service with Air Defense Command. Originally designated the F-96 on account of its considerable changes, the F-86D incorporated an interception radar and fire-control system and carried an armament of 27 70mm (2.75in) Mighty Mouse rockets in a retractable ventral tray. The other new-build model was the F-86K (120 built), essentially a D-model adapted for service with NATO allies, and with gun armament. ‘Sabre Dogs’ accounted for 2504 of the total production run of 9860 North American F-86s. A total of 827 ‘Sabre Dogs’ were subsequently rebuilt as F-86Ls, featuring an increased-span wing and updated avionics.
In the neat undercarriage of the Sabre, the nosewheel unit retracted backwards to lie in the forward fuselage, while the mainwheels retracted inwards to lie in the fuselage.
This total was added to by licensed production in Australia by the Commonwealth Aircraft Corporation (112 aircraft) and in Canada by Canadair (1815). The CAC Sabre differed in its use of the 33.35kN (7500lb) thrust Rolls-Royce Avon 26 engine and armament of two 30mm (1.1in) cannon. A total of 100 were built. Canadair produced F-86Es for the USAF, as well as the similar Sabre Mk 2 (290 aircraft) for Canada and NATO allies. The 438 Sabre Mk 4s built by Canadair were supplied to the UK, with General Electric engines, while the 370 Sabre Mk 5s had 28.26kN (6355lb) Orenda 10 turbojets.
Last of the Canadian production models was the Sabre Mk 6, 655 of which were completed with the 32.35kN (7275lb) Orenda 14. Finally, Fiat in Italy was responsible for assembly of 221 F-86Ks that were provided in kit form by North American Aviation, and Mitsubishi of Japan assembled a further 300 Sabres.
Fury: Sabres at Sea
A first-generation naval jet fighter, the North American FJ-1 Fury had provided the initial basis for the design of the land-based Sabre. Successive marks of F-86 then contributed to the further development of swept-wing FJ Fury derivatives for use by the U.S. Navy and Marine Corps. The experimental XFJ-2 was essentially a naval version of the F-86E, equipped with arrester hook, extending nose gear and catapult hitches. A total of 200 FJ-2 production models followed, these being equipped with folding wings. T...
