Design and Development
The YF-95 was a development of the F-86 Sabre, the first aircraft designed around the new 2.75 in (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 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 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 40 ft 4 in, with 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/25 kN (from the F-86D-45 production blocks onward). A total of 2,504 D-models were built.

Famous quotes containing the words design and/or development:
“Nowadays the host does not admit you to his hearth, but has got the mason to build one for yourself somewhere in his alley, and hospitality is the art of keeping you at the greatest distance. There is as much secrecy about the cooking as if he had a design to poison you.”
—Henry David Thoreau (1817–1862)
“Other nations have tried to check ... the fulfillment of our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions.”
—John Louis O’Sullivan (1813–1895)
