^ out of curiosity, between the 22 and 23, which platform was a better base (i say base as both would have to be updated) for naval operations?
Both teams NATF entries were very different from their ground-based counterparts, only sharing components (radar, some avionics, engines and so on). Swing wings for the Lockheed-Boeing-General Dynamics trio, high wings with canards for the Northrop-McDonnell-Douglas team.
There is a separate thread for the NATF designs.
A possible scenario for the purchase of both could be a slightly different Desert Storm history. Say the Iraqis got their hands on some advanced surface to air missiles from an undisclosed origin, that the coalition intelligence failed to identify and locate.
During the initial strikes, those unexpected and unscathed SAMs take a high toll on coalition fighter bombers, including several 4th TFW F-15E Strike Eagle.
The air campaign is far more contested, longer than anticipated, Iraqi Migs and Mirages benefit from the SAM coverage and claim several air-to-air victories. Only the F-117s are allowed in certain areas. Iraqis manage to identify some patterns and set up a trap where they're able to shot down several tankers and a precious F-117 (something along the lines of what happened in Serbia in 1999).
Iraq is defeated nonetheless, it just took several weeks and more losses to locate and destroy those SAMs.
Long story short; while the YF-22 is selected in April 1991 at the end of the ATF program, the USAF takes lessons: Strike Eagle are too vulnerable to modern SAMs and F-117s lack self defense capabilities. The proposed F-23A (or more likely the tandem seat variant) with its large tandem weapons bay is then selected as a replacement for the strike role.
The F-22A got the air superiority role, the F-23 (while keeping its air to air capabilities) got the specialized long range strike role.
How does that sound?
