To Little to Late
Winemaker,
Sadly, the Defiant completed these flight tests 5 months after the final report deadline had passed.
Additionally, if you read the full Flight Global article for details, you will see that ADS 33 Level 1 HQ was not demonstrated in high speed (for FLRAA) flight. The V-280 demonstrated Level 1 HQ up to specification cruise speed.
With the smaller FARA platform, and more schedule time for development, X-2 technology may prove itself viable.
