North American F-86D Sabre
The North American F-86D Sabre (sometimes called the "Sabre Dog" or "Dog Sabre") was a transonic jet all-weather interceptor of the United States Air Force and others. Based on North American's F-86 Sabre day fighter, the F-86D had only 25 percent commonality with other Sabre variants, with a larger fuselage, larger afterburner engine, and a distinctive nose radome.
==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.
