F-22 vs. F-23: Why the Ultimate Stealth Air Duel Won't Happen
“Interestingly the YF-22 and YF-23 had exactly the same trimmed AoA of 60°. The YF-23 could do it without thrust vectoring. Those V-tails were very powerful especially when coupled to an unstable airframe,” said one source who is intimately familiar with both the YF-23 and the Raptor. “The YF-22 probably had an advantage at very, very low airspeeds but neither company had enough time to investigate dynamic low speed, high AOA maneuvering. This was a good example of how a competition needs to consider the PR value of flight test events.
