The Northrop/McDonnell Douglas YF-23 was an American single-seat, twin-engine stealth fighter aircraft technology demonstrator designed for the United States Air Force (USAF). The design was a finalist in the USAF's Advanced Tactical Fighter (ATF) competition, battling the Lockheed YF-22 for a production contract. Two YF-23 prototypes were built with the nicknames "Black Widow II" and "Gray Ghost".
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. Several companies submitted design proposals; the USAF selected proposals from Northrop and Lockheed. Northrop teamed with McDonnell Douglas to develop the YF-23, while Lockheed, Boeing and General Dynamics developed the YF-22.
The YF-23 was stealthier and faster, but less agile than its competitor. After a four-year development and evaluation process, the YF-22 was announced the winner in 1991 and entered production as the Lockheed Martin F-22 Raptor. The U.S. Navy considered using the production version of the ATF as the basis for a replacement to the F-14, but these plans were later canceled. The two YF-23 prototypes were museum exhibits as of 2009.
The Lockheed Martin F-22 Raptor is the best air superiority fighter ever built, but could America have done better? When the YF-22 prototype won the contract for the Advanced Tactical Fighter (ATF) in April 1991, it was a lesser plane compared to the Northrop YF-23 in many ways. Though the YF-22 was a more maneuverable aircraft, the YF-23 had far greater supersonic cruise capability—especially when outfitted with the General Electric YF120 variable cycle engines. Even when powered by the less powerful Pratt & Whitney YF-119, the YF-23 had the ability to fly an entire sortie at supersonic speeds above Mach 1.4 (explained to me sometime ago by Barry Watts at the Wilson Center—who was an analyst on the Northrop team at the time). The sleek prototype jet could also cruise at slightly more tha...

This is was the competitor for the ATF jet plane, Its rival was the F-22 made by lockheed. This is a unique fighter, its very stealthy, and can go supersonic without afterburners. I'm kinda bummed out that this might never be made in large numbers. Only two or so prototypes were made. I love this plane, look at it!
The Northrop/McDonnell Douglas YF-23 was an American prototype fighter aircraft designed for the United States Air Force. The YF-23 was entered in Advanced Tactical Fighter competition but lost out to the Lockheed YF-22, which entered production as the F-22 Raptor.
YF-23 Black Widow vs YF-22 Raptor usaf last fighter competition
Underneath a big clock
At the corner of 5th Avenue and 22nd Street
I stood and waited for a girl I knew
At the spot where we agreed to meet
It was four minutes of two
At four of two, I stood waiting for the girl
I was four minutes early for the date we had planned
I was planning to say I was in love with her
Just as soon as she showed for a two o'clock date
And the clock said four of two
At four of two, I was staring into space
She was not yet late, according to the clock
I was feeling nervous so I kept looking up
At the clock sticking out of the side of the building
And it still said four of two
At four of two, I began to feel tired
And I rubbed my eyes, and again I checked the time
It seemed as if the sky was growing dark
But I felt reassured when I looked at the clock
And it still said four of two
I lay my head down on the sidewalk
So in case she were coming I would have a better view
But no one was there so I stretched out
And closed my eyes for a second or two
It was four minutes of two
At once I awoke to a futuristic world
There were flying cars and gigantic metal bugs
I'd grown a beard, it was long and white
But I knew that the girl would be coming very soon
For though everything had changed, there was still that clock
