In 2021, Russia conducted a DA-ASAT missile test that destroyed one of its own satellites, and Russia has reportedly threatened US and allied satellites (Arms Control Association, Forbes, Air & Space Forces Magazine). The engagement and the accusation must occur during the question's open period to count. A "DA-ASAT" is "a medium- or long-range missile launching from the Earth to damage or destroy a satellite in orbit" (Center for Strategic & International Studies). All US satellites must be registered (UN Office of Outer Space Affairs, Cornell - 14 CFR § 450.217). Damaged caused by debris from a Russian DA-ASAT missile striking another orbiting object will not count.
