Northrop/McDonnell Douglas YF-23

Northrop / McDonnell Douglas · United States · first flew 1990 · fighter

The Northrop/McDonnell Douglas YF-23 was one of two prototype competitors in the USAF Advanced Tactical Fighter competition that ultimately selected the Lockheed YF-22, which became the F-22 Raptor. Two YF-23 prototypes were built, demonstrating exceptional stealth and speed.

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Unmistakable due to its diamond-shaped wing planform, V-tail replacing conventional horizontal and vertical stabilizers, and deeply blended body with trapezoidal engine inlets. The absence of a conventional tail and the very broad wing chord are unique identifiers.

History

The YF-23 first flew on 27 August 1990. During the ATF fly-off against the YF-22, it demonstrated supercruise capability and superior stealth characteristics, but the USAF ultimately selected the YF-22 in April 1991, citing better maneuverability and lower risk. Both YF-23 airframes survive: one at the National Museum of the USAF and one at the Western Museum of Flight.

Variants

Two prototypes were built — PAV-1 in gray ('Black Widow II') and PAV-2 in tan ('Gray Ghost'), powered by different engine types (Pratt & Whitney YF119 and General Electric YF120 respectively).

Where you'll see it

Never entered production or service; both prototypes are preserved in US air museums.
