Vityaz missile system

50R6 Vityaz missile system (ЗРС Витязь) or S-350E — Russian middle-range guided missile system developed by GSKB Almaz-Antey. It's developed for the purpose of replacing S-300PS and S-300PT-1A. The system design traces its roots from the joint South Korean/Russian KM-SAM project.

The naval version with 9M96E guided missile under development would be called Redut.

Structure of 50R6A Vityaz missile system:
 * 50N6A multifunctional radar station
 * 50K6A command post
 * 50P6 launcher
 * Guided SA missiles 9M96.

All vehicles are based on BZKT chassis.

It is expected that the missile system would be tested in the fall of 2013.

Testing is expected to be completed in 2014, with mass production beginning in 2015, and deliveries to the Russian Military in 2016. The system would replace the S-300, and complement other systems including the Morfey, S-400, and S-500.
