Ο Νόρθροπ/ΜακΝτόνελ Ντάγκλας YF-23 ήταν ένα αμερικανικό μονοθέσιο, δικινητήριο μαχητικό αεροσκάφος επίδειξης τεχνολογίας stealth σχεδιασμένο για την Πολεμική Αεροπορία των Ηνωμένων Πολιτειών (USAF). Το σχέδιο ήταν φιναλίστ στον διαγωνισμό Advanced Tactical Fighter (ATF) της USAF, πολεμώντας το Lockheed YF-22 για συμβόλαιο παραγωγής. Κατασκευάστηκαν δύο πρωτότυπα YF-23, με τα παρατσούκλια "Black Widow II" και "Gray Ghost".

Teh Νόρθροπ YF-23 was a prototype fighter aircraft designed by Northrop Corporation for the United States Air Force’s Advanced Tactical Fighter (ATF) program. The YF-23 competed against the Lockheed YF-22 for the contract to produce the next-generation air superiority fighter for the USAF. The YF-23 was a stealthy, twin-engine, twin-tail aircraft with a diamond-shaped wing and a V-shaped tail. The YF-23 had two variants: one with Pratt & Whitney YF119 engines and one with General Electric YF120 engines.
The YF-23 flew for the first time on August 27, 1990, and completed six test flights before the ATF program was concluded in April 1991. The USAF selected the YF-22 as the winner of the ATF competition, and the YF-23 program was canceled. The two YF-23 prototypes were retired and sent to museums, where they remain on display to this day.
