I think there was another radar in between, a more powerful EIRS radar, not the 'mobile' version (T), but fixed one (S)The system presented by İsmail Demir as the S400 equivalent domestic missile will probably be a system with exoatmospheric interception capability against ballistic missiles and capable of reaching altitudes of around 150-200km. In parallel to these developments, a giant early warning ballistic missile detection radar system called YIR, which will have thousands of km ranges was scheduled as next target after EIRS become operational. As EIRS was developed to be the main early warning radar of Siper family, I think YIR will be the main radar of the S400 equivalent domestic missiles.
