Thanks IFMU,
In the article text was my earlier question answer:
”
WASHINGTON — The Sikorsky-Boeing developed SB-1 Defiant coaxial demonstratoraircraft hit 232 knots in a descent, and 211 knots in straight and level flight, meeting the U.S. Army’s speed requirements for its future long-range assault aircraft it plans to field by 2030.”
However I believe any new lower speed requirement of 230 Kts would be in level flight, not in descent.
