The Air and Space Defense Forces conducted a test of the new interceptor of the Moscow missile defense system at the Sary-Shagan test site. According to a VKS representative, "after a series of tests the interceptor fully confirmed technical characteristics of the interceptor and the combat crews successfully completed the mission by hitting the notional target with required accuracy." The test appears to have taken place on 16 September 2021.

The video appears to show defragmentation of the interceptor at a fairly low altitude (at 0:40 h/t DS). It is not clear if this was a planned event or a range safety detonation.

Previous test of the interceptor took place in April 2021.
