North American NA-157 / F-93

na-f93


The North American F-86C developed into the YF-93A and eventually became the third design in the penetration fighter competition with the McDonnell XF-88 and Lockheed XF-90. The YF-93A was a bigger, and bulkier than the Sabre. The nose inlet of the F-86 design was replaced with side-mounted inlets and the fuselage was widened to house a 12835kg thrust Pratt & Whitney turbojet. The result was a larger, heavier machine with longer range and greater load-carrying capacity than the Sabre.

On 9 June 1948, the USAF ordered 118 F-93s, but the order was cancelled a year later. The YF-93A lost its second chance to attain production status when it emerged a poor third in the penetration fighter contest which, as it turned out, did not result in any production contract anyway.

The first of the two YF-93As, also known as the company NA-157, was first flown on 24 January 1950. The two machines underwent various modifications during evaluation, including changes in the shape of their lateral air inlets.

After the USAF was no longer a potential buyer, the two airframes were turned over to the National Advisory Committee for Aeronautics (NACA), where they were employed in various tests until eventually being retired and scrapped.
