The combat teams of the Leningrad Air Force and Air Defense Army from the Western Military District successfully test-fired new S-400 surface-to-air missile systems after they were accepted for service, the District’s press office reported on Wednesday.

At the Kapustin Yar practice range, the combat teams of a surface-to-air missile battalion accepted the new S-400 systems from the manufacturer.

"After the acceptance, the anti-aircraft gunners test-fired the systems against unique Favorit-RM hypersonic target missiles that simulated a notional enemy’s air attack weapons," the press office said in a statement.

The new S-400 systems struck all the designated targets, the press office of the Western Military District said.
