The Air and Space Defense Forces conducted another test of a "new modernized" interceptor of the Moscow missile defense system at the Sary-Shagan test site. The test appear to take place on April 1, 2018. The new interceptor is often referred to as 53T6M.

The first time description of a test included mentions of improvement of the Moscow missile defense system was the June 2017 test. It is possible that it was the first test of the new interceptor, but it is more likely that it was a regular annual test of the old 53T6 (these traditionally take place in June). The words "new modernized" appeared only in November 2017, and then again in February 2018. So, this is probably the third test of the 53T6M.
