It can also detect stealth aircraft and other targets at all altitudes of up to 30 km and at a maximum range of 400 km. This air defense missile system can simultaneously engage 36 targets.

An S-400 battery includes a 30K6E battle command system, up to 6 TEL (Transporter Erector Launcher) vehicles each with four missiles ready to be fired. There is also a 55K6E command control unit and 91N6E search radar which has a range of around 600 km.

The aerial threats are detected by the 91N6E radar and tracked by 92N6E engagement and launching control radar. Citing open sources information, the 92N6E radar has a range of around 340 km.
