The Northrop/McDonnell Douglas YF-23 is an American single-seat, ... Specifications (YF-23A) YF-23 3-view drawing from Northrop/McDonnell Douglas YF-23 PAV-1 in flight.
Northrop and McDonnell Douglas submitted the YF-23. Lockheed, Boeing and General Dynamics proposed and built the YF-22, which, although marginally slower and having a larger radar cross-section, was more agile than the YF-23. The Lockheed team was picked by the Air Force as the winner of the ATF in April 1991.
However, the cited books in this article are written by people with direct connections to the YF-23, namely Alfred "Paul" Metz, YF-23 PAV-1 test pilot, and Air Force Materiel Command researchers and archiver, Tony Landis and reputed aviation author Dennis Jenkins. If that is the case, I can upload a non-free thumbnail version under fair use.

Northrop team's YF-23 (above) and Lockheed team's YF-22 (below) flying in formation. The first YF-23 made its maiden flight on 27 August 1990 and the first YF-22 first flew on 29 September 1990. [53] Flight testing began afterwards at Edwards Air Force Base and added the second aircraft for each competitor in late October 1990. [54]
The Northrop/McDonnell Douglas group promoted the larger YF-23." I might be wrong, but I don't think anything would be lost here by deleting the first sentence and going with: "Lockheed, Boeing and General Dynamics entered the YF-22, while Northrop and McDonnell Douglas promoted the larger YF-23."
