F-86D Sabre

The North American F-86D/K/L Sabre (initially known as the YF-95 and widely known informally as the "Sabre Dog",) was an American transonic jet fighter aircraft. 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 air-to-air 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 "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 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 a barrage of 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 , 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 (from the F-86D-45 production blocks onward). A total of 2,504 D-models were built.

Operational history

On 18 November 1952, F-86D ''51-2945'' set a speed record of . 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 . 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 .
