The North American F-86D/K/L Sabre (initially known as the YF-95 and widely known informally as the "Sabre Dog") is an American transonic jet interceptor. Developed for the United States Air Force in the late 1940s, it was an interceptor derivative of the North American F-86 Sabre. While the original F-86 Sabre was conceived as a day fighter, the F-86D was specifically developed as an all-weather interceptor. Originally designated as the YF-95 during development and testing, it was re-designated the F-86D before production began, despite only sharing 25% commonality of parts with the original F-86. Production models of the F-86D/K/L differed from other Sabres in that they had a larger fuselage, a larger afterburning engine, and a distinctive nose radome. The most-produced Sabre Dog variants (the "D" and "G" models) also mounted no guns, unlike the Sabre with its six M3 Browning .50 caliber machine guns, instead mounting unguided Folding-Fin Aerial Rocket (FFAR) “Mighty Mouse” rockets. The "K" and "L" Sabre Dog variants mounted four 20mm M24A1 cannon.
Design and development

The YF-95 was a development of the F-86 Sabre, the first aircraft designed around the new 2.75-inch (70 mm) "Mighty Mouse" Folding-Fin Aerial Rocket (FFAR). Begun in March 1949, the unarmed prototype, 50-577, first flew on 22 December 1949, piloted by North American test pilot George Welch and was the first U.S. Air Force night fighter design with only a single crewman and a single engine, a J47-GE-17 with afterburner rated at 5,425 lbf (24.1 kN) static thrust. Gun armament was eliminated in favor of a retractable under-fuselage tray carrying 24 unguided Mk. 4 rockets, then considered a more effective weapon against enemy bombers than automatic cannon fire. A second prototype, 50-578, was also built, but the YF-95 nomenclature was short-lived as the design was subsequently redesignated YF-86D.
The fuselage was wider and the airframe length increased to 40 ft 4 in (12.3 m), with a clamshell canopy, enlarged tail surfaces and AN/APG-36 all-weather radar fitted in a radome in the nose, above the intake. Later models of the F-86D received an uprated J-47-GE-33 engine rated at 5,550 lbf (24.7 kN) (from the F-86D-45 production blocks onward). A total of 2,504 D-models were built.
On 18 November 1952, F-86D 51-2945 set a speed record of 698.505 mph (1,124.1 km/h). Captain J. Slade Nash flew over a three km (1.8 mi.) course at the Salton Sea in southern California at a height of only 125 ft (38 m). Another F-86D broke this world record on 16 July 1953, when Lieutenant Colonel William F. Barns, flying F-86D 51-6145 in the same path of the previous flight, achieved 715.697 mph (1,151.8 km/h).

Fiat built 62 F-86Ks for France (1956-1957), assigned to EC 1/13 "Artois", EC 2/13 "Alpes", and EC 3/13 "Auvergne" Squadrons. Serials were 55-4814/4844, 55-4846/4865, 55-4872/4874, 55-4876/4879.
Acquired 35 F-86Ds from the US. Were received in 1961 and retired in 1967 but kept as back up until 1969. F-86D was the first all weather fighter in Greek Air Force. F-86Ds were assigned to 337 and 343 Squadrons. Until 1964 they were in natural metal. Until after retirement they were in NATO camo.
Fiat produced 121 F-86Ks for Italy, 1955-1958. Also, 120 U.S. F-86Ks were acquired. F-86s were assigned to the AMI air groups: 6 Gruppo COT/1 Stormo, 17 Gruppo/1 Stormo, 23 Gruppo/1 Stormo, 21 Gruppo/51 Aerobrigata, 22 Gruppo/51 Aerobrigata and 12 Gruppo/4 Aerobrigata.
Acquired 130 U.S.-made F-86Ds and operated them between 1961 and 1974. 32 of these were modified into a reconnaissance variant utilizing 3 Kodak K-24 cameras mounted in place of the FFAR rockets, the IF-86D.
