YF-22 YF-23 comparison
Definitive comparision between the YF-22 and YF-23 is difficult because relatively little information on the performance of the YF-23 has found its way into the public domain. It was not in Northrop's nor the USAF's interest to disclose the full extent of the performance publicly. Careful examination of relevant AIAA material would give the most accurate publicly available assessment. The performance figures revealed during Dem/Val were generic and sanitised, designed to give the public a rough impression of the ability of these aircraft to meet requirements.
There were, in my opinion, only 2 areas where these aircraft had distinctly different capabilities in terms of flight performance: close range ACM/post stall manoevuring, and straight line speed. Obviously, with thrust vectoring, the

In hindsight, now that comparisons can be made between the prototypes and EMD versions, it is apparent that Northrop's prototype was more of a 'bare-bones' hot rod, with a rudimentary weapons bay, and highly sinuous contours optimised for minimum drag, whereas the YF-22 was more representative of the final EMD F-22A. The 6 month delay that Lockheed requested from the AF SPO was put to good use making major revision of their concept, whereas Northrop made few major changes to their design, they were fundamentally happy with it. It has not been revealed how they ulitilized the extra six months.
