Replacement for Older Medium-Range SAMs
S-350 was developed to modernize Russia's medium-range air-defense layer.
The S-350 Vityaz program was developed by Almaz-Antey as a modern medium-range surface-to-air missile system. It is often described as filling the space between short-range systems and long-range S-300/S-400 batteries, while replacing older S-300PS and related assets in some roles. Russian testing and initial delivery milestones made it visible around 2019 and 2020.
