This is old news to the Russians...see excerpt from your own link...the U.S. just ID'd the ship...

"The U.S. did not know in advance that Ukraine was going to target the Moskva, officials said, and was not involved in the decision to strike. Maritime intelligence is shared with Ukraine to help it defend against attack from Russian ships, officials added.

The U.S. role in the sinking has not been previously reported. But NBC News detailed last month how American intelligence shared with Ukraine had been instrumental in Ukraine’s successes to date, including in helping Ukraine target Russian forces and avoid Russian attacks."
