The Northrop/McDonnell Douglas YF-23 is an American single-seat, twin-engine, stealth fighter technology demonstrator prototype designed for the United States Air Force (USAF).
The Northrop YF-23A, unofficially named the Black Widow II, emphasized stealth characteristics. To lessen weight and increase stealth, Northrop decided against using thrust vectoring for aerodynamic control as was used on the Lockheed YF-22A. Northrop built two YF-23A prototypes.

The YF-23 rapidly completed taxi testing with increasing speeds, culminating in the final high-speed test to 120 knots on August 11. Unofficially dubbed ‘Black Widow II’, Northrop’s Prototype Air Vehicle (PAV) number 1 took to the air for the first time on August 27 making a near flawless one hour flight.
The YF-23 was tested to a top speed of Mach 1.8 with afterburners and achieved a maximum angle-of-attack of 25°. The maximum speed is classified, though sources state a maximum speed greater than Mach 2 at altitude and a supercruise speed greater than Mach 1.6.
The YF-23 Black Widow II, developed by Northrop/McDonnell Douglas, was a cutting-edge stealth air-superiority fighter. This aircraft stood out for its unique design and advanced features but ultimately did not win the contract in the competition against the YF-22.
The YF-23A “Black Widow II” was a supersonic “Stealth” fighter. Along with its Stealth capabilities, the YF-23A was designed to “Supercruise”. This meant that the YF-23A “Black Widow II” could cruise supersonic without the use of engine augmentation or “afterburning.”
The YF-23 Black Widow II is a American stealth fighter, developed in the late 1980s, untouched by combat, rival to the Lockheed Martin F-22 Raptor.
Featuring a diamond-shaped planform, two large, sharply-canted ruddervators, and a serrated aft profile, the high performance aircraft was larger than the F-15 it was designed to replace. The YF-23 employed stealth characteristics and was capable of supersonic cruise flight without afterburner.
The four-way ATF competition pitted the Northrop/McDonnell Douglas YF-23A “Black Widow II” team against the Lockheed/Boeing/General Dynamics YF-22A “Lightning II” team. The Pratt & Whitney YF119 engine competed with the General Electric YF120 engine.
He flew Northrop’s YF-23 on its first flight during the Advanced Tactical Fighter (ATF) competition that pitted the jet against Lockheed’s YF-22 and also went on to do the same for the F-22A. In the video below, he describes what the ATF program was like from the inside and just how good the YF-23 actually was.
Two YF-23 prototypes were built with the nicknames “Black Widow II” and “Gray Ghost”. See Test Flight Video – Click In the 1980s, the USAF began looking for a replacement for its fighter aircraft, especially to counter the USSR’s advanced Sukhoi Su-27 and Mikoyan MiG-29.
Lockheed’s YF-22 possessed striking looks, but the YF-23, dubbed the Black Widow II, was truly otherworldly, with diamond-shaped wings to reduce radar observability and a very thin side profile...
