There have long been reports that the ongoing delays with the commissioning of the Admiral Gorshkov frigate have to do with defects in its air defense systems. These were thought to be primarily related to problems with integration of the Poliment Redut air defense missile system. The Poliment system was designed to be Russia’s answer to AEGIS, with four phased array antennas that are able to track 16 targets at the same time. The Redut system consists of four or eight vertical launch systems that launch three types of missiles. The 9M100 is the short-range missile, with a range of up to 15km. The 9M96M is the medium-range missile, with a range of 40-50km. Finally, the 9M96 long-range missile is supposed to have a range of up to 150km.
It now appears that the Redut’s problems are much more serious than just integration. A recent report notes that the Ministry of Defense has stopped trials of the system because of continuing problems with the 9M96 long-range missile. Specifically, the missiles appear to fail after three seconds of flight. Some reports indicate that the Redut system works well hitting targets up to 40km away, but fails in the long range. The implication is that the short and medium range missiles work well, but the long range missile does not. Nevertheless, this may be an improvement over previous results, as trials of the Redut system on the Steregushchiy class corvettes in 2014 showed that they were only able to hit targets at distances of up to 15km because the medium-range Furke-2 radar system was not functioning properly.
