When Ukraine successfully targeted Russia’s prized warship last month with anti-ship cruise missiles, they had some help from the United States.
Ukrainian forces, having spotted a Russian warship in the Black Sea, called their American contacts for confirmation that it was in fact the Moskva, sources familiar with the events told CNN. The US responded that it was, and provided intelligence about its location.
It is not clear whether the US knew Ukraine would move to strike the ship, however, and the US was not involved in that decision, the sources said.
The ship sank after it was struck by two Ukrainian cruise missiles on April 14, dealing a huge blow to the Russian military.
The episode, first reported by NBC News, reflects the Biden administration’s increasingly forward-leaning posture when it comes to sharing intelligence with Ukraine, part of a broader policy shift toward helping Ukraine defeat Russia decisively on the battlefield and significantly weaken its military.
But it also raises questions about what both the US and Russia’s red lines are when it comes to US military support to Ukraine.
The US has for months been providing Ukrainian forces with intelligence about Russian troop movements inside Ukraine, including intercepted communications about Russian military planning. It also provides Ukraine with maritime awareness information to allow them to better understand the threat posed by Russian ships in the Black Sea, many of which are firing missiles onto Ukrainian territory.
