Better Than U.S Patriot System! Russian S-400 air defense system gets ground attack upgrade

Overall, the S-400 – which has been in use since 2007 – is a huge step up from the S-300, and utilises a full suite of targeting apparatus, such as multifunction radar, command and control and autonomous detection, ensuring that the system is capable of providing a layered defence. While largely untested in an operational environment, the S-400 is potentially twice as effective in comparison to the capable S-300 system.
